TheSocialist International, commonly known as theSecond International, was apolitical international ofsocialist andlabour parties formed in Paris on 14 July 1889. At a time of growing industrial working-class movements and the expansion of suffrage, it brought together autonomous national parties into a loose international federation. It continued the work of theFirst International (1864–1876), from which it inherited both the legacy ofKarl Marx and the conflict withanarchists. The organization was dominated by the powerfulSocial Democratic Party of Germany (SPD), whose organizational and theoretical leadership heavily influenced the other member parties.
The International established the annual celebration ofInternational Workers' Day on 1 May and popularised the demand for aneight-hour day. Its early congresses were preoccupied with expelling anarchists and defining its mission as one based on parliamentary political action. After 1900, the International was increasingly confronted with the internal divisions of the socialist movement, particularly the rise ofrevisionism in Germany and the debate over socialist participation in "bourgeois" governments, sparked by theMillerand affair in France. The 1904Amsterdam Congress, which saw a major debate between French socialistJean Jaurès and German leaderAugust Bebel, condemned revisionism and ministerialism, marking the highest point in the influence of the International.
From 1905, the prevention of war became the International's central task, and it came to be seen as the world's most important anti-militarist political force. At the congresses ofStuttgart (1907),Copenhagen (1910), and Basle (1912), it passed increasingly urgent resolutions calling for international working-class action, including strikes, to stop the outbreak of war. However, the International was powerless to stop thecrisis of July 1914. Following the assassination of its most charismatic anti-war leader, Jaurès, its major member parties—including those in Germany, France, Austria, and Great Britain—rallied to support their respective nations' efforts inWorld War I, precipitating the International's collapse.
By the 1880s, the political and economic climate of Europe was shifting away from the mid-century dominance ofliberal political economy. TheLong Depression of the 1870s spurred a return toprotectionism, exemplified byGermany's tariffs of 1879. Rapidindustrialisation, especially in Germany, created a new urbanproletariat and brought the "social question" to the forefront of public discussion. The expansion ofsuffrage in countries like Germany and France, andits extension in Britain in 1884, made it possible for mass political parties representing the working class to emerge.[1] Astrade unions grew in strength and purpose, organised socialism evolved from a set of doctrines held by theorists into the creed of these new mass parties.[2]
The legacy of theFirst International, which had been formally dissolved in 1876 after its internal collapse in 1872, had awakened Europe to the possibility of international working-class action and had endowed the idea of "The International" with a potent, if partly mythical, revolutionary tradition.[3] Several unsuccessful attempts had been made to revive the organization during the late 1870s and 1880s, notably at congresses inGhent in 1877 andChur, Switzerland, in October 1881.[4] The Chur congress acknowledged that the time was not yet ripe for a formal relaunch, concluding that strong and properly organised national parties were essential preliminaries to the revival of the International upon a stable foundation.[5]
In 1878,Otto von Bismarck's government passed theAnti-Socialist Laws, which banned socialist meetings, associations, and newspapers. The persecution, which lasted until 1890, ultimately strengthened the party. Its leaders gained prestige as martyrs, and its organisation was forced to become more disciplined. During this period, 1,300 publications were suppressed and 1,500 party activists were sentenced to a total of 1,000 years' imprisonment.[8] Despite this, the party's vote grew from 310,000in 1881 to 763,000in 1887.By 1890, when the laws expired, the SPD had thirty-five seats in theReichstag and received nearly 1.5 million votes.[9] The SPD's combination of Marxist revolutionary rhetoric and practical, law-abiding political activity created a model that was widely admired and emulated by emerging socialist parties across Europe, including in Austria, Belgium, and Switzerland.[10]
In France, the socialist movement was more divided, drawing on diverse and sometimes conflicting traditions: theutopianism ofCharles Fourier, the insurrectionism ofAuguste Blanqui, theanarchism ofPierre-Joseph Proudhon, and the Marxism imported byJules Guesde.[11] The brutal suppression of theParis Commune in 1871 had shattered the French working-class movement, which only began to revive in the late 1870s.[12] In 1879, Guesde's Marxist group founded theFrench Workers' Party (POF).[13] They were soon challenged by the "Possibilists" led byPaul Brousse, who advocated for gradual municipal reforms and were deeply suspicious of Marx's attempts to dictate doctrine from London.[14] Other factions, such as the Blanquists underÉdouard Vaillant, and later theAllemanists and independent socialists aroundBenoît Malon, added to the disunity.[15]
In Great Britain, the predictions of Marxist theory were not being realised. The class struggle was muted, and the trade unions were focused on collective bargaining rather than independent political representation.[16] Small Marxist groups existed, such asHenry Hyndman'sSocial Democratic Federation andWilliam Morris'sSocialist League, but the most significant contribution to socialist thought came from the non-MarxistFabian Society, founded in 1884, which promoted a philosophy of gradual reform derived from theutilitarian tradition.[17] The1889 London dock strike marked a turning point, ushering in an era of "new unionism" among unskilled workers and increasing socialist influence in the trade unions. In 1888, the Scottish minerKeir Hardie founded theScottish Labour Party, marking an early step toward independent labour representation in Parliament.[18]
In Russia, autocratic rule made a mass movement impossible. The revolutionary movement was composed of small groups of exiles who debated doctrine and tactics, primarily in Switzerland. Following the assassination ofTsar Alexander II in 1881, revolutionary thinkers split between those who favoured terrorism and those who looked to the peasantry. A third way emerged in 1883 whenGeorgi Plekhanov,Vera Zasulich, andPavel Axelrod founded the Marxist "Emancipation of Labour" group.[19] They argued that Russia must follow the path of Western Europe, developing a capitalist economy and an industrial proletariat that would form the basis for a future socialist revolution.[20]
Anarchist ideas, stemming fromMikhail Bakunin's influence in the First International, remained a powerful force, particularly in Spain and Italy, and competed everywhere with the more centralised and disciplined model of Marxist parties.[21]
The revival of international socialism was closely tied to the growing movement for aneight-hour day. This demand originated in the United States and Australia in the 1850s and was taken up by French socialists in the 1880s, who saw international labour legislation as its primary goal.[22] The centenary of theFrench Revolution in 1889, celebrated with agreat exhibition in Paris, provided a natural occasion for a new international socialist congress.[23] However, the divisions within the French socialist movement led to the convocation of two rival congresses. The Possibilists, led by Brousse, collaborating with the BritishTrades Union Congress (TUC), organised a congress that met in the Rue de Lancry. The Marxists, led by Guesde and supported by Liebknecht and the SPD, held their own congress in the Salle Petrelle.[24]
The Théâtre des Fantaisies-Parisiennes inParis, site of the founding congress of the Second International
Liebknecht and others had hoped for a single, unified congress, but the intransigence of both French factions, and the scepticism ofFriedrich Engels, made this impossible.[25] The rivalry between the two meetings was intense and at times chaotic, with delegates drifting between them and anarchists disrupting the proceedings of both.[26] Despite the confusion, the Marxist congress that opened on 14 July 1889 in the Salle Petrelle (soon moved to the Théâtre des Fantaisies-Parisiennes) is considered thefounding congress of the Second International.[27] It was attended by nearly 400 delegates from twenty countries and included most of the prominent socialist leaders of Europe.[28] It was a more distinguished gathering than its Possibilist rival, which was dominated by French delegates and included only a few prominent foreign figures like Hyndman.[29]
The delegates saw themselves as heirs to the legacy of the First International; Liebknecht declared that the old International had not died but "passed into the mighty working-class movement", and that the new body was its "offspring".[30] Liebknecht and Vaillant were elected joint presidents, their handshake symbolising the desired solidarity between German and French socialism. Other notable attendees included Bebel,Victor Adler from Austria, Hardie and Morris from Britain, Plekhanov from Russia, and Marx's daughterEleanor Marx-Aveling and son-in-lawPaul Lafargue.[31] The congress was greeted as the "first parliament of the international working class," which had assembled to conclude a "sacred alliance of the international proletariat."[32]
The congress devoted much of its time to hearing reports on the state of the socialist movement in each country, breaking the isolation that had followed the collapse of the First International.[33] On its final day, it passed a series of important resolutions that would set the agenda for the International for years to come. The most significant of these was the decision to organise "a great international demonstration" on a fixed date to demand an eight-hour working day. The date of 1 May was chosen, adopting a proposal made by theAmerican Federation of Labor in 1888.[34] This established the tradition ofMay Day as an international workers' holiday. The first such demonstration in 1890 was a major success, with impressive rallies and work stoppages in many European countries.[35] The congress also passed resolutions condemningstanding armies in favour of a "people in arms" or popularmilitia, and affirming that socialists should participate in elections where possible but "without compromising with any other parties".[36] The debates over the implementation of these resolutions, particularly the nature of the May Day demonstration, revealed the deep tactical differences that existed between the member parties from the outset.[37]
Early congresses and exclusion of anarchists (1890–1896)
The first years of the new International were defined by the struggle against the anarchists, whose acts ofpropaganda of the deed, including assassinations and bombings, captured public attention in the 1890s. While some socialists sympathised withdirect action, the official Marxist parties saw this strategy as a threat, both because it invited government repression and because it undermined their focus on organised political action.[38] The question of anarchist participation dominated the first three congresses after the founding meeting.
At theBrussels Congress of 1891, the anarchists were formally excluded. The organisers had invited only those parties and labour organisations that recognised the necessity of political action.[39] The congress made the celebration of May Day an annual event, and, largely on German initiative, added the demand for peace to its central themes.[40] Despite the official exclusion of anarchists, sympathisers including the Dutch socialistFerdinand Domela Nieuwenhuis, attended and argued for revolutionary tactics against war, proposing that any declaration of war be met with a general strike by conscripts. The proposal was overwhelmingly rejected in favour of a resolution by Vaillant and Liebknecht that placed faith in the existing parliamentary and electoral tactics of the socialist parties.[41]
The conflict escalated at theZurich Congress of 1893. The proceedings opened with a tumultuous debate over credentials, as a group of German "dissident" socialists and anarchists, includingGustav Landauer, demanded admission. Bebel delivered a vehement speech denouncing them, and a resolution was passed limiting attendance to parties that accepted "political action". This led to chaotic scenes as the anarchists were physically expelled, shouting "We protest!".[42] The resolution stated: "All Trade Unions shall be admitted to the Congress: also those Socialist Parties and Organisations which recognise the necessity of the organisation of the workers and of political action... By 'political action' is meant that the working-class organisations seek, in as far as possible, to use or conquer political rights and the machinery of legislation for the furthering of the interests of the proletariat and the conquest of political power."[43] Among those excluded was the youngRosa Luxemburg, representing a Polish socialist group.[44]
The final showdown occurred at theLondon Congress of 1896. Anarchists including Landauer andErrico Malatesta again appeared and, after being denied delegate status, disrupted the proceedings from the public galleries. After a long debate, which included a passionate appeal for tolerance from the British trade unionistTom Mann, the congress reaffirmed the Zurich resolution on political action, making the exclusion of anarchists from the International definitive.[45] Despite this, the composition of the congress remained heterogeneous. The British delegation alone included 159 delegates from trade unions, 121 from the Social Democratic Federation, 117 from theIndependent Labour Party (ILP), and 22 from the Fabian Society, among many others.[46] As the British observerGeorge Bernard Shaw noted, the consistent expulsion of revolutionary dissidents showed how far the International had moved toward becoming a respectable, and predominantly parliamentary, organisation.[47] This struggle cemented the International's character as a body of organised political parties, setting the stage for the next major internal conflict: the debate over reform versus revolution.[48]
With the anarchists excluded, the International became a more coherent but by no means monolithic body. Its growth in size and electoral success forced its member parties to confront a fundamental dilemma: whether to work for revolutionary overthrow of the capitalist system or to seek gradual reforms within it. This tension manifested as "revisionism" in Germany and "ministerialism" in France.[49] At theParis Congress of 1900, the International decided to establish a permanent secretariat and headquarters inBrussels, creating theInternational Socialist Bureau (ISB) to coordinate its activities.[50]
The theoretical challenge was articulated byEduard Bernstein, a leading SPD intellectual who had spent years in exile in Britain and been influenced by Fabianism.[51] In a series of articles published from 1896 and culminating in his 1899 bookThe Preconditions of Socialism (Die Voraussetzungen des Sozialismus), Bernstein argued that many of Marx's core predictions were proving incorrect. Capitalism was not on the verge of collapse; the middle class was not disappearing; and the working class was not sinking into ever-increasing misery.[52] He concluded that the socialist movement should abandon its revolutionary goal and openly embrace a path of gradual, evolutionary reform. In a much-criticised phrase, he declared, "What is generally referred to as the ultimate aim of Socialism means nothing to me; it is the movement itself which means everything."[53]
Bernstein's ideas were fiercely attacked by theorthodox Marxists, led byKarl Kautsky, the party's chief theorist, who argued that revisionism abandoned the essential elements of Marx's teaching—the class struggle and the inevitability of revolution. Bebel and other party leaders, anxious to preserve the revolutionary orthodoxy on which the party's identity was based, supported Kautsky.[54] Luxemburg also made her reputation as a theorist with her polemicSocial Reform or Revolution?.[55] The SPD formally condemned revisionism at its Hanover congress in 1899 and again more forcefully at its Dresden congress in 1903.[56]
While the Germans debated in theory, the French faced the problem in practice. TheDreyfus affair deeply divided French society and created a political crisis that realigned French politics.Jean Jaurès, leader of the independent socialists, threw himself into the campaign to defend Dreyfus and the Republic against nationalists, militarists, and monarchists.[57] This led him into an alliance with "bourgeois" republicans. The crisis culminated in June 1899 when the new Prime Minister,Pierre Waldeck-Rousseau, invited the independent socialistAlexandre Millerand to join his "Government of Republican Defence" as Minister of Commerce.[58] Millerand's decision to accept a post alongside GeneralGaston Alexandre Auguste, Marquis de Galliffet, the suppressor of the 1871 Commune, caused a massive controversy within both French and international socialism.[59]
The "Millerand case" split the French socialists. The revolutionary wing, led byJules Guesde, condemned Millerand's participation as a betrayal of the class struggle. The reformist wing, led by Jaurès, cautiously defended it as a necessary emergency measure to save the Republic.[60] The International addressed the issue at its Paris Congress of 1900. After a heated debate, it passed a compromise resolution, drafted by Kautsky, which condemned socialist participation in bourgeois governments in principle but allowed for it as a temporary and exceptional emergency measure, provided it was approved by the socialist party.[61] The issue led to a formal split in France in 1902 with the creation of two rival parties: Guesde's revolutionarySocialist Party of France and Jaurès's reformistFrench Socialist Party.[62]
The debate reached its climax at theAmsterdam Congress of 1904. The central issue was a resolution, based on the SPD's 1903 Dresden resolution, which condemned revisionism and "all attempts to disguise existing class conflicts in order to facilitate support of bourgeois parties."[63] The debate pitted the two greatest figures of the International against each other: Jaurès and Bebel.
Jaurès delivered a powerful speech defending his reformist strategy and attacking the political impotence of the German SPD. He argued that while the SPD had millions of voters, its rigid doctrine prevented it from exercising real political power in Germany's autocratic system. In France, by contrast, socialists could and must ally with democrats to defend liberty and advance social progress. "What at present most weighs on Europe and the world," he declared, "is not the alleged compromises... of the French Socialists... but... the political powerlessness of German Social Democracy."[64]
Bebel, in response, reiterated the orthodox Marxist position that there could be no collaboration with the class enemy. Republics were just as much "class states" as monarchies, and the only task of socialists was to prepare for the inevitable seizure of power.[65] Ultimately, the prestige and disciplined voting of the German delegation ensured victory. The Dresden resolution was adopted by 25 votes to 5, with 12 abstentions.[66] The congress also passed a resolution calling for the French socialists to unite. Pressured by the International, Jaurès accepted the verdict. In April 1905, the two French parties merged to form theFrench Section of the Workers' International (SFIO), based on the orthodox principles dictated by the Germans.[67]
The International's principle ofproletarian solidarity was continually challenged by the growing force of nationalism. Its official doctrine was that class, not nationality, was the primary division in human society. At its 1891 Brussels Congress, it condemned "anti-semitic andphilosemitic agitation as one of the manoeuvres by which the capitalist class and reactionary governments try to... divide the workers".[68] However, in an age of rising national consciousness, this position became increasingly difficult to maintain.
The most acute test of socialist internationalism occurred within theAustrian Social Democratic Party. The party, operating in the multinationalAustro-Hungarian Empire, was a "little International" in itself, priding itself on uniting German, Czech, Polish, and other workers within a single federal framework.[69] While German-speaking leaders likeVictor Adler dominated, the party had a large and growing Czech membership, as well as Polish, Slovene, and Italian sections. At its 1899 Brünn Congress, the party proposed a programme for reorganising the empire into a federal state of autonomous nationalities.[70] However, conflicts grew, particularly within the trade unions, where Czech workers demanded separate unions from their German counterparts.[71] In 1910, the matter was brought before theCopenhagen Congress of the International, which upheld the principle of single, unified trade unions, siding with the German-Austrian leadership. In response, a majority of the Czech socialists split from the party in 1911, and the "little International" of Austria effectively broke down.[72]
A similar problem existed within the German SPD over its Polish-speaking members inPosen andSilesia. Leaders likeRosa Luxemburg, herself Polish, insisted that Polish workers should belong to the unified German party. Others argued that the party was insensitive to Polish national feeling. The SPD's official stance remained one of uncompromising centralism.[73]
In theBalkans, Western European socialist parties generally viewed the preservation of thestatus quo as essential to peace, fearing that any conflict could ignite a wider war. Balkan socialist parties, however, argued that thestatus quo itself was the source of conflict. They called for the overthrow of theOttoman and Austro-Hungarian empires and the formation of a democratic Balkan federation that would be free from the intrigues of the great powers. This conflict of views later came to a head during theBalkan Wars, but the major parties' desire to contain the conflict prevented the International from adopting the Balkan socialists' anti-imperialist, non-interventionist stance.[74]
The International also debated colonial policy at itsStuttgart Congress of 1907. A vocal minority, including delegates from Britain and the Netherlands and German revisionists likeEduard David, argued that colonies were a fact of life and that socialists should work for a "socialist colonial policy" to promote reforms and the welfare of native populations, rather than simply demanding an end to all colonialism.[75] The orthodox Marxist majority, however, passed a resolution condemning colonialism in principle as an inherent part of the capitalist system of exploitation. The vote was close, 127 to 108, revealing a deep division on the issue.[76]
TheRusso-Japanese War of 1904–1905 and the subsequent1905 Russian Revolution refocused the International on the growing threat of war. The opening of the Amsterdam Congress had featured a symbolic handshake between Plekhanov and the Japanese socialistSen Katayama.[77] The revolution revived the idea of themass strike as a political weapon, not just for domestic reforms but as a means to prevent war.[78] From 1905, the International's congresses were dominated by debates over how to implement its anti-war principles.
The debate at theStuttgart Congress of 1907 was particularly significant. Four different positions emerged. The French radicalGustave Hervé argued for strikes within the military and insurrection in response to any war. Guesde and the French Marxists argued that no special action was needed, as the normal course of the class struggle would eventually abolish war. Bebel and the German leadership advocated for parliamentary pressure and reiterated the call for national militias to replace standing armies. Jaurès and Vaillant proposed a more active policy, including the use of mass strikes.[79] The final resolution was a compromise, but it included a crucial last-minute amendment drafted by Luxemburg andVladimir Lenin. It declared that if war should break out, it was the duty of socialists "to intercede for its speedy end, and to strive with all their power to make use of the violent economic and political crisis brought about by the war to rouse the people, and thereby to hasten the abolition of capitalist class rule." This text became the foundational statement of the revolutionary left's position on war.[80] The Stuttgart resolution allowed different factions to leave the congress satisfied but without a clear guide to action. As historianGeorges Haupt later noted, "each protagonist could regard the Stuttgart resolution as his victory."[81]
TheCopenhagen Congress of 1910 revisited the issue amidst the growingAnglo-German naval arms race.Keir Hardie and Vaillant put forward an amendment explicitly calling for a general strike, particularly in industries supplying armaments, as the most effective means of preventing war. After a tired and inconclusive debate, the matter was referred to theInternational Socialist Bureau (ISB) for further study, with the issue to be definitively settled at the next international congress scheduled for Vienna in 1914.[82]
In November 1912, as theBalkan Wars threatened to escalate into a general European conflict, the International held an extraordinary emergency congress inBasel, Switzerland. The event was a massive and emotional demonstration for peace. Delegates marched to theBasel cathedral, led by children singing socialist songs, where the bells were rung in a gesture of welcome.[83] The congress unanimously adopted a manifesto that reiterated the Stuttgart resolution and called on the workers of all countries to oppose war.[84] The congress itself was preceded by massive anti-war demonstrations in the major European capitals, and the atmosphere of unity and enthusiasm gave the International an "illusory power" in the eyes of its leaders.[85] The congress marked, in historianJames Joll's words, "the high point of the International's optimistic self-confidence".[86] Many leaders left Basle convinced that the strength of the international socialist movement was a genuine guarantee of peace. Jaurès expressed this hope, declaring that the International was "strong enough to speak in this tone of command to those in power and if necessary to follow up their words with deeds."[87]
The successful containment of the Balkan Wars without a general European conflict created a wave of optimism within the International. By 1913, many leaders came to believe that the immediate threat of war had receded. This mood was reinforced by a new interpretation of imperialism, advanced byKarl Kautsky and others, which suggested that the growing economic interdependence of the great powers would make war between them irrational and counter-productive. This theory of "ultra-imperialism" argued that capitalist interests were becoming aligned with the preservation of peace.[88] This feeling ofdétente was reflected in practical initiatives, such as the Franco-German parliamentary conference held in Berne in May 1913, and a new emphasis on international arbitration and a "triple alliance" between Britain, France and Germany as the guarantors of European peace.[89] The optimism was not universal, with Jaurès and the revolutionary left remaining more cautious, but the prevailing mood in 1913 and early 1914 was one of confidence that the International's strategy of prevention was working and that a lasting peace was attainable.[90]
Map of European alliances on the eve ofWorld War I, 1914
The optimistic spirit of Basle proved illusory. On 28 June 1914,Archduke Franz Ferdinand of Austria was assassinated inSarajevo, but the seriousness of the crisis was not immediately apparent to socialist leaders, many of whom left for their summer holidays.[91] When Austria-Hungary presented itsJuly Ultimatum to Serbia on 23 July, the International was caught off guard.[92] The socialist press across Europe condemned the ultimatum, and on 25 July, the SPD leadership issued a strong appeal for peace, declaring that "No drop of a German soldier's blood must be sacrificed to the Austrian despots' lust for power", though it stopped short of outlining a concrete plan of action.[93] Austria-Hungary declared war on Serbia on 28 July, startingWorld War I.
On 29 July, the ISB held an emergency meeting in Brussels. The mood was one of anxiety, but not yet of despair.[94] The leaders present—including Jaurès from France, Adler from Austria,Hugo Haase from Germany, and Hardie from Britain—reaffirmed their commitment to the Stuttgart and Basle resolutions. Adler delivered a deeply pessimistic report on the mood in Vienna, confessing the powerlessness of the Austrian party to resist the tide of war fever and warning that the International should not count on its resistance: "The war is already with us... We are at war, our newspapers are suppressed. We are living in a state of emergency... any action on our part... is completely impossible".[95] In contrast, Haase expressed confidence that the German working class, which had just participated in huge anti-war demonstrations, could be mobilised against war.[96] The Bureau's only concrete decision was to move the upcoming international congress from Vienna to Paris, rescheduling it for 9 August to act as a massive protest.[97] The meeting concluded with a mass rally at theCirque Royal, where Jaurès made his final, powerful speech for peace and international arbitration.[98]
Two days later, on 31 July,Jaurès was assassinated in a Parisian café by a young nationalist fanatic. His death was a devastating blow, depriving both French socialism and the International of its most charismatic and dedicated anti-war leader.[99] On the same day, Germany issued its declaration of a "state of imminent danger of war," and on 1 August, Germany declared war on Russia and general mobilisation began in France and Germany. A last-minute attempt at coordination failed whenHermann Müller, sent by the SPD to Paris, found the French socialists, reeling from Jaurès's murder and facing a German invasion, unwilling to consider voting againstwar credits.[100]
On 4 August 1914, the final collapse occurred. In Berlin, the SPD parliamentary group, swayed by a combination of fear of government repression, loyalty to the state in the face of the "Russian menace", and the patriotic fervour of its own base, voted unanimously for war credits. Haase, who had opposed the war in internal party meetings (where the vote was 78 to 14 in favour of the credits),[101] read the party's declaration in the Reichstag, announcing the policy ofBurgfrieden (civil truce).[102] In Paris, on the same day, the socialists also voted for war credits, joining theUnion sacrée (sacred union) of national defence.[103] Soon, the socialists in Austria, Belgium, and Great Britain had also rallied to their respective governments. Socialists entered the wartime governments in France (Jules Guesde,Marcel Sembat) and Belgium (Émile Vandervelde).[104] The Second International was dead. Only in Serbia and Russia did socialist deputies vote against the war.[105]
The war irrevocably split the international socialist movement. The majority factions in the belligerent countries, known as "social patriots", sided with their governments. A minority opposed the war from a pacifist or revolutionary standpoint. In December 1914, the ISB, now based inThe Hague in the neutral Netherlands, made a futile attempt to unite the parties of neutral countries at a conference in Copenhagen in January 1915.[106] In response, the social-patriotic parties of theAllied countries held their own conference in London in February 1915, followed by the parties of theCentral Powers in Vienna in April 1915.[107]
The anti-war minority organised itself as theZimmerwald movement. In September 1915, a small group of anti-war socialists from Germany, France, Russia, and other countries met at theZimmerwald Conference in Switzerland. The conference exposed a growing rift between a pacifist majority, who sought an immediate peace without annexations or indemnities, and a revolutionary left, led byVladimir Lenin. Lenin called for turning the imperialist war into a civil war and for the creation of a new, Third International.[108] The division deepened at theKienthal Conference in April 1916.[109] The final major attempt to reunite the movement during the war was the abortiveStockholm Conference of 1917. Initiated by neutral socialists and thePetrograd Soviet after theFebruary Revolution in Russia, the conference aimed to bring all socialist parties together to broker a peace settlement. However, the Allied governments refused to issue passports to their delegates, causing the conference to collapse before it could convene.[110]
After the war, attempts to revive the International failed amidst the split between the social democratic and communist wings of the labour movement. In February 1919, the first postwar conference was held inBerne. Delegates were present from most of the former neutral and Allied parties, as well as the German Majority Socialists and Independents, but the Belgians refused to sit with the Germans, and the parties that had supported the Zimmerwald Left, including the French, Italian, and Swiss parties, were absent.[111] The conference was dominated by two issues: a debate over "war responsibility", which resulted in a compromise resolution that left the French delegates unsatisfied, and a resolution that condemned theBolshevik dictatorship in Russia and endorsed parliamentary democracy. A commission was appointed to reconstruct the International.[112]
A month later, in March 1919, theCommunist International (Comintern or Third International) was founded inMoscow, based on a total rejection of the "social patriotism" and failed legacy of the Second International.[113] The conferences ofthe reconstituted Second International atLucerne in August 1919 andGeneva in July 1920 represented an ever-shrinking "rump" of the old organisation, as many of its former member parties either left to join the Comintern or disaffiliated to seek a third way.[114] In February 1921, this latter group, which included the GermanIndependents (USPD), the French SFIO, the British ILP, and the Austrian Social Democrats, founded theInternational Working Union of Socialist Parties (IWUSP), known as the "Vienna Union" or the "Two-and-a-half International". The Vienna Union criticised both the Second and Third Internationals and sought to unite the divided socialist movement.[115] The formal end of the Second International came in May 1923, when the Berne International and the Vienna Union merged at a congress in Hamburg to form theLabour and Socialist International.[116]
The collapse of the Second International in 1914 has been the subject of extensive historical debate. Explanations range from the polemical—Lenin's view that it was a "betrayal" by opportunist leaders—to the structural. Historians likeGeorges Haupt have argued that the collapse was not a sudden event, but the result of the International's long-standing contradictions. Its pacifist strategy was built for prevention and proved useless once war was declared.[117] Its member parties were federated and autonomous, lacking any mechanism for enforcing joint action. Furthermore, its anti-war doctrine was based on an optimistic and flawed understanding of imperialism that developed after 1912, leading its leaders to misread the political climate of 1914. They failed to appreciate that the patriotism of the masses could outweigh their class loyalty, and they were unprepared for the rapid escalation of the crisis and the psychological impact of mobilisation.[118] The fatalistic resignation that took hold on 1 August was not a reversal of policy, but the logical outcome of a strategy that had no alternative once its primary tactic—preventing the war from starting—had failed.[119]
The fundamental ideological division within the International was between "reformists" and "revolutionaries". Reformists, such as the German Revisionists and British Fabians, believed that socialism could be achieved gradually and peacefully through the existing democratic state, which they viewed as a neutral instrument that could be captured and used by the majority.[120] Revolutionaries, following orthodox Marxism, held that the state was an organ of class rule that must be overthrown. This group was itself divided. The mainstream of the German SPD expected revolution to come after a long period of preparation via constitutional methods,[121] while the revolutionary left, including Lenin and Luxemburg, anticipated a more imminent collapse of capitalism through war or economic crisis.[122] Beyond these state-centric views, a "pluralist" andlibertarian tradition, includingsyndicalists,co-operators, and anarchists, rejected the extension of state power and advocated for a decentralised society based on free associations of producers and consumers.[123]
Despite its ultimate failure, the Second International left a lasting legacy. The period of its existence was what many socialists considered the "apostolic period of Socialism", a time of preaching and propagation to establish a mass movement before the assumption of political power.[124] It established the rituals and traditions of mass social democracy—May Day,International Women's Day, and the anthem "The Internationale".[125] In countries like Germany and Austria, it created a vibrant "society within the state", a political and cultural subculture that encompassed the entire life of its members, from choral societies and workers' libraries to a cradle-to-grave welfare system.[126] In practice, as historianJames Joll argues, Marxist social democracy was tempered by liberal ideals, giving it both strength and weakness. It left a tradition of organised political action based on a belief in democracy, humanity, and personal liberty which survived its political and theoretical failures.[127]
International Socialist Bureau (1900–1916): The BSI was the only permanent organizing committee of the international, founded to provide a degree of continuity between conferences. It met yearly alongside the regular conferences to coordinate decision-making between the member parties. After 1914 the BSI failed to meet aside from sporadic attempts at one-on-one meetings between delegates, contributing to the dissolution of the international.[128]
The JSWP was incorporated as a sub-group of theSocialist Revolutionary Party in 1907, but had a separate consultative vote in the Stuttgart congress.[139][140]
Founding member. Membership is unclear after 1891. Initially called the Gas Stoker's Union, gas workers were a very important force behind the8 hour day.[138][137]
After World War I, there were three Socialist conferences organized by theBerne International. All of them were held in Switzerland. These served as a bridge to the creation of theLabour and Socialist International.
Scheduled for February 1920, it was actually convened on 31 July. Sidney Webb as committee chairman drafted a resolution entitled "Political System of Socialism", that distanced the Second International from Leninism, but emphasized it was "ever more urgent that Labour should assume power in society". It also moved the Secretariat from Brussels to London and set the "next congress of the Second International in 1922", but this did not take place.[143]
