TheLithuanian Civil War of 1389–1392 was the second civil conflict betweenJogaila,King of Poland andGrand Duke of Lithuania, and his cousinVytautas. At issue was control of theGrand Duchy of Lithuania, then the largest state in Europe.[1] Jogaila had been crowned King of Poland in 1386; he installed his brotherSkirgaila as ruler of Lithuania. Skirgaila proved unpopular and Vytautas attempted to depose him. When his first attempt to take the capital city ofVilnius failed, Vytautas forged an alliance with theTeutonic Knights, their common enemy – just as both cousins had done during theLithuanian Civil War between 1381 and 1384. Vytautas and the Knights unsuccessfully besieged Vilnius in 1390. Over the next two years it became clear that neither side could achieve a quick victory, and Jogaila proposed a compromise: Vytautas would become Grand Duke and Jogaila would remain Superior Duke. This proposal was formalized in theOstrów Agreement of 1392, and Vytautas turned against the Knights. He went on to reign as Grand Duke of Lithuania for 38 years, and the cousins remained at peace.
Thefamily of Gediminas ruled a state that covered the territories of present-day Lithuania,Belarus,Ukraine,Transnistria, and parts of Poland andRussia. Gediminas died in 1341; afterwards his sonsAlgirdas andKęstutis, the fathers ofJogaila andVytautas, co-ruled the Grand Duchy peacefully. However, after Algirdas' death in 1377, Kęstutis, Jogaila, and Vytautas began a power struggle. During their first conflict, theLithuanian Civil War between 1381 and 1384, Vytautas and Jogaila both struck short-lived alliances with the Teutonic Knights. Vytautas did not manage to seize the throne and reconciled with Jogaila in 1384.
Jogaila created a significant new alliance with the Kingdom of Poland when he secured an agreement, known as theUnion of Krewo (August 1385), to marry the twelve-year-old Queenof PolandJadwiga of Poland. He married Jadwiga and was crownedjure uxoris king of Poland in February 1386.[1] As a condition to the marriage and coronation, Jogaila agreed to renounce paganism himself and Christianize his subjects, and establish apersonal union between Poland and Lithuania. The Union was an unwelcome development for the Teutonic Knights, as it united Poland and Lithuania, two states hostile to the Order, and aChristianized Lithuania deprived the Knights of their ideological justification for waging theLithuanian Crusade.[2] Thus the Order sought opportunities to undo thePolish–Lithuanian union; they demandedSamogitia, a section of western Lithuania that bordered theBaltic Sea,[3] and refused to recognize Jogaila's baptism in 1386.[4]
Vytautas became duke ofHrodna andPodlaskie; Jogaila known now by his Christian name Władysław II (Władysław II Jagiełło) designated his brotherSkirgaila regent in Lithuania.[5][6] Skirgaila, who also ruled Vytautas' patrimony inTrakai, was disliked by theLithuanian nobility.[citation needed] Vytautas, on the other hand, became increasingly popular; Władysław II began to see him as a rival.[7] Vytautas was supported by Lithuanians who resented the Polish interpretation of the recent Union of Krewo.[8] These Lithuanians wished to maintain distinct legal structures and reserve official posts for Lithuanians.[5] The Lithuanian elites also resented the changes in government that king Władysław II implemented there.[7]

Jogaila had sentKlemens Moskarzewski to establish a Polish garrison inVilnius and stabilize the situation, but this move only angered the opposition.[9] In May 1389 Jogaila tried to mediate the conflict between Skirgaila and Vytautas inLublin. Vytautas was pressured into signing a formal document declaring that he was loyal to Skirgaila and supported him, but his position as Duke ofLutsk was not formally acknowledged.[10] Vytautas secured his position in Lutsk, and turned his sights onVilnius. According to Teutonic testimony at theCouncil of Constance, Vytautas planned to take advantage of his sister's wedding by sending wagons filled with meat, hay, and other goods to Vilnius. The wagons would be escorted by armed men, who would capture the castle once inside the city.[11] This plan was uncovered by a German spy and the conspirators were executed.[3] In another setback, two of Vytautas' strongest allies, his brotherTautvilas and his brother-in-lawIvan Olshanski, lost their territories inNavahrudak andHalshany.[10]
Vytautas then sought a military alliance with the Knights, sending captive knightMarquard von Salzbach to negotiate. On 19 January 1390 inLyck Vytautas signed theTreaty of Lyck affirming the terms of an earlier agreement, theTreaty of Königsberg, signed in 1384 during his first conflict with Jogaila.[10] Under the terms of this treaty, the Knights were promisedSamogitia, up to theNevėžis River, in exchange for their military assistance. Having been earlier betrayed, the Knights asked for hostages as a guarantee of Vytautas' loyalty: his brothersSigismund andTautvilas, his wifeAnna, his daughterSophia, his sisterRymgajla, his favoriteIvan Olshanski, and a number of other nobles.[6][12]

In May, a delegation of 31 Samogitian nobles arrived inKönigsberg and promised loyalty to Vytautas by signing theTreaty of Königsberg.[10] The joint forces of Vytautas and the Teutonic Knights consisted largely of volunteers and mercenaries from western Europe, notably from France, the German states, and England. Henry, Earl of Derby, the future KingHenry IV of England[13] and Marshal of FranceJean Le Maingre were among the participants.[14] The English crusaders left detailed records of their actions in Prussia and Lithuania, and their exploits were mentioned byGeoffrey Chaucer in theCanterbury Tales, possibly as a compliment to the English knights and the future king.[15] In the meantime, Jogaila achieved some military successes; his forces captured several castles in Podlaskie, leaving them to be guarded by Polish garrisons, and took Hrodna in April 1390 after a six-week siege.[14]
The newly assembled coalition organized a number of small campaigns in Lithuania; the largest was undertaken at the end of summer. During this campaign the Knights burned wooden castles atKernavė, possibly the first capital of Lithuania, which never recovered from the destruction.[16] While the army was laying siege toGeorgenburg, Grand MasterConrad Zöllner von Rothenstein died. The coalition decided to abandon this siege and march on Vilnius instead, as such a large army could not easily be re-assembled.[14] On 11 September 1390, the joint forces launched a five-week siege on the city.[7] Vilnius' castles were held by Skirgaila, commanding combined Polish, Lithuanian, andRuthenian troops.[17] The Knights reduced much of the outer city to ruins[13] and managed to destroy theCrooked Castle, which was never rebuilt.[18] Vytautas' brotherTautvilas Kęstutaitis and Jogaila's brotherKarigaila died during the siege.[6] The besiegers ran into various difficulties. Their supplies of gunpowder were dwindling, the weather was deteriorating, the terms of service for some volunteers from western Europe ended, and the Knights needed a new Grand Master.[19] They decided to return to Prussia. The siege did not bring an end to the conflict, but it demonstrated an increased dissatisfaction with Jogaila among the regional inhabitants.[7]

On 21 January 1391 Vytautas' only daughter,Sophia of Lithuania, marriedVasili I of Russia,Grand Duke of Moscow. This alliance strengthened Vytautas' influence in Slavic lands and represented a potential new ally against Poland.[9] At the same time, Jogaila's brotherLengvenis was losing his power inVeliky Novgorod to Moscow.[20] The Teutonic Knights were idled during the protracted selection of their new Grand Master,Konrad von Wallenrode; theirgeneral chapter delayed his election.[19] In May 1391, the new master mortgaged Złotoria (Slatoria), a castle nearThorn, fromWładysław Opolczyk,count palatine ofSigismund of Hungary, for 6,632guldens.[21][22] This angered Jogaila and he invadedDobrzyń Land, but was driven away.[10]
Von Wallenrode called for new volunteers from France, England, and Scotland. Among those who responded wasWilliam Douglas of Nithsdale.[23] During the autumn of 1391 the Teutonic Knights organized another campaign against Vilnius.[6] InKaunas they organized a lavish feast,[23] which was prominently featured inKonrad Wallenrod, an 1828 poem byAdam Mickiewicz. They devastated the nearby towns ofUkmergė andMaišiagala, but lacked the resources for a second siege on Vilnius.[6] In November 1391 Vytautas attacked the areas nearMerkinė and Hrodna, cutting off the easiest communication route between Jogaila and Skirgaila.[24]
In the meantime the Knights were buying lands in Prussia. In May 1392, von Wallenrode began negotiations withSigismund of Hungary to buyNeumark for 500,000guldens.[25] Negotiations fell apart as the title to the land was contested by several dukes.[26] The Neumark purchase was closed withJobst of Moravia only in 1402. During July 1392, the Knights agreed to pay Władysław Opolczyk 50,000 guldens for theDobrzyń Land,[25] which had been contested amongPiast dukes since 1377.[27] Opolczyk, the ruler ofOpole inSilesia, had little interest in the volatile regions to his north.[27] In 1392, he circulated a proposal to partition Poland among the Teutonic Knights, theHoly Roman Empire, Silesia, andHungary, but it was rejected.[28] These purchases by the Knights threatened Poland's northern borders.[25]
Neither Jogaila nor Vytautas had gained a clear advantage and the territories of the Grand Duchy affected by the civil war were being devastated.[5]Polish nobles were dissatisfied with the war; Jogaila was spending a great deal of time on Lithuanian matters and the expected benefits of the Union of Krewo had not materialized.[9] The Union was meant to strengthen Polish control overGalicia,Moldavia, andWallachia rather than to create fresh troubles in the north.[25] Jogaila was preoccupied with the management of his court, battles in the southeast, and his sickly wife.[25] He attempted to replace Skirgaila with his younger brotherVygantas, but this brother died under unclear circumstances – according to rumor he was poisoned by either Vytautas or Skirgaila.[23]Klemens Moskarzewski was replaced with Jan Oleśnicki fromKraków as governor of Vilnius.[25] Jogaila decided to seek a compromise with Vytautas.[6]
In spring 1392, Jogaila proposed a compromise through his envoy,Henry of Masovia,Bishop of Płock: Vytautas would become the Grand Duke of Lithuania if he would recognize Jogaila as the Supreme Duke.[6] By summer, Vytautas had secured the release of many of the hostages he had given to the Knights, and accepted the offer.[9][25] Since this agreement with Jogaila was reached in secret, the Knights suspected nothing when Vytautas invited them to the festivities at his headquarters, theRitterswerder Castle on an island in theNeman River.[6] Most of the prominent guests were taken prisoner and Vytautas' army proceeded to attack and destroy the undermanned wooden castles of Ritterswerder, Metenburg, and Neugarten (New Hrodna) near Hrodna.[20][25][29]
TheOstrów Agreement, formalizing the arrangement and ending the civil war, was signed on 4 August 1392. Vytautas became Grand Duke and reclaimed his patrimony inTrakai while Skirgaila was compensated with the Principality ofKiev, where he died in 1397.[5] While Vytautas was technically a vassal of Jogaila, he exercised considerable power in the Grand Duchy. His independence was legalized in the 1401Union of Vilnius and Radom.[30] Vytautas ruled Lithuania until his death in 1430; his relationship with Jogaila during these years is sometimes likened to the peaceful power-sharing demonstrated by their fathers Algirdas and Kęstutis.[28] The Knights, betrayed for the second time, resumed their wars against Lithuania. They sought to take Samogitia, which Vytautas had twice promised them. TheTreaty of Salynas was signed in 1398, leaving Samogitia to the Knights, to quiet the Duchy's western front while Vytautas was organizing a major campaign against theGolden Horde. Vytautas suffered a major defeat at theBattle of the Vorskla River in 1399.[5] The cousins joined their forces at theBattle of Grunwald in 1410, which ended the threat from the Teutonic Orders.[2]
