TheInternational Mercantile Marine Company, originally theInternational Navigation Company, was atrust formed in the early twentieth century as an attempt byJ.P. Morgan tomonopolize the shipping trade.
IMM was founded by shipping magnatesClement Griscom of theAmerican Line andRed Star Line,Bernard N. Baker of theAtlantic Transport Line,J. Bruce Ismay of theWhite Star Line, andJohn Ellerman of theLeyland Line. TheDominion Line was also amalgamated. The project was bankrolled byJ.P. Morgan & Co., led by financierJ. P. Morgan. The company also had working profit-sharing relationships with the GermanHamburg-Amerika and theNorth German Lloyd lines. The trust caused great concern in the British shipping industry and led directly to the British government's subsidy of theCunard Line's new shipsRMSLusitania andRMSMauretania in an effort to compete.
IMM was a holding company that controlled subsidiary corporations that had their own subsidiaries. Morgan hoped to dominate transatlantic shipping throughinterlocking directorates and contractual arrangements with the railroads, but that proved impossible because of the nature of sea transport, American antitrust legislation, and an agreement with the British government. One of IMM's subsidiaries was the White Star Line, which owned theRMSTitanic. Analysis of financial records shows that IMM wasoverleveraged and suffered from inadequate cash flow that caused it to default on bond interest payments in late 1914. As a result, a "friendly" receivership was put in effect in 1915, which allowed IMM to reorganize its finances; it emerged from the receivership in 1916.[1] Saved byWorld War I, IMM eventually re-emerged, after a merger with Roosevelt Steamship Company, as theUnited States Lines, which itself went bankrupt in 1986.[2]
A proposed subsidy bill in theUnited States Congress failed, which became widely apparent by April 1902[a] and the company thus was never truly successful. Beginning in the 1920s, the company underwent a series of corporate acquisitions and mergers, which resulted in its becoming theUnited States Lines in 1943.

As the shipping industry prospered in the late 19th century, some sought to create a trust that would monopolize U.S. shipping companies. However, all negotiations in this regard in the 1890s fell short. The intervention of John Pierpont Morgan, one of the richest men in the world, changed that.[5]
The Atlantic Transport Line, owned by Bernard N. Baker and having both passenger and cargo ships,[6] competed intensely with British and other shipping companies. Baker tried to sell his company to John Ellerman, chairman of the cargo-carrying Leyland Line, who had tried unsuccessfully to take possession of the Cunard Line and HAPAG, two powerful European companies. Negotiations between Baker and Ellerman, advanced but ultimately fell through.[7]
Meanwhile, J. P. Morgan had already concluded agreements withClement Griscom, president of the International Navigation Company, which operated the Red Star Line and the American Line. Finally, in December 1900, after six months of negotiations, the Atlantic Transport Line joined INC.[8]
Subsequently, Baker, J. P. Morgan, and Simon Bettle Jr. (representative of the INC) negotiated with Ellerman, this time with a view to redeem his property. There would be two companies that would join the trust. The name of one of them was revealed in April 1901: the Leyland Line.[9] The second turned out to be the prestigious White Star Line, bought by Morgan's team, after long negotiations, in April 1902.[10][11][12] On 1 October 1902, JP Morgan & Co. announced the founding of the International Mercantile Marine Company, more commonly called IMM.[13][14] (Constituent elements of IMM, including INC (chartered in 1871),[15] had however been operating for many years already.)[7] IMM was incorporated inNew Jersey.[16]

Morgan's role evolved over the years. Being American, he could not directly own British ships, but he could own the company that owned the ships.[7] In 1902, the IMM carried 64,738 passengers, a total buoyed by high immigration to the United States. The IMM had signed a partnership with the two most important German shipping companies, Norddeutscher Lloyd and HAPAG, which carried a total of 66,838 passengers. The German-Morgan agreement, signed in New York on 20 February 1902,[b] was a key step in the formation of what was to become the IMM, but did not fully address long-standing competitive friction between and amongst the major German and British transatlantic shipping companies.
Responses in the United Kingdom helped intensify these rivalries. Cunard Line, one of the British shipping companies with independent significance, received grants from the British government for the construction of two large ocean liners, theLusitania and theMauretania, which were placed into service in late 1907.[18] The competitive response from the IMM group came in 1908 whenHarland & Wolff was authorized to build the White Star Line'sOlympic class ocean liner trio:RMS Olympic,RMS Titanic, andHMHS Britannic.[19][20]
Since 1902, IMM had an agreement with James Pirrie, chairman of Harland & Wolff and member of the management of the White Star Line, stating that all the ships of the company would be built by Harland & Wolff.[7] Ships of the company were also shifting from one company to another, like theBelgic, built for the White Star Line, which was transferred to the service of the Red Star Line under the nameSS Belgenland (1914), or theRegina became theWesternland.[21] This allowed the IMM to schedule a ship each day from the United Kingdom, and allowed passengers to change their tickets to another ship of the company. Baker retired from the direction of the Atlantic Transport Line shortly after its integration with the IMM, and was replaced byPhilip Franklin. He later became vice president of IMM, while Griscom was replaced as president by Joseph Bruce Ismay in 1904 (who was also president of the White Star Line).[22]


The early 1910s marked a turning point for the IMM. Indeed, on 15 April 1912, theTitanic, flagship of its fleet,sank during her maiden voyage. Besides the financial and human losses, the sinking had repercussions on the organization of the trust. Through theAmerican commission of inquiry devoted to the sinking, SenatorWilliam Alden Smith openly attacked the very principle of the company and Morgan.[23] As had been arranged before Titanic sank, J. Bruce Ismay retired as president of IMM in 1913 and was succeeded byHarold Sanderson[24] Morgan died on 31 March 1913.[25] After the 1915–16 receivership, Sanderson was succeeded as president by Franklin, who had been the receiver.[26]
However, the sinking of theTitanic did not bring about the end of the IMM. Although theoretically powerful due to its continued influence with some of the top American, British, and German shipping companies, the overseeing company never managed to overcome its own financial problems, nor dominate the bulk of the North Atlantic shipping trade, and was therefore not as successful as expected.[7] The company went into receivership in 1915 and was placed in the hands of Franklin, who managed to save it. In the late 1920s, he received grants from the government to American ships (built in the United States or flying the flag) and in 1926 it sold the White Star Line to theRoyal Mail Steam Packet Company for £7 million, of which £2.35 million was still unpaid when the Royal Mail Group, which was overleveraged and undercapitalized, collapsed in the early 1930s.[27] In 1930, IMM possessed 30 vessels. There were 19 in 1933 and only 11 by 1935.
The ailing company merged with theRoosevelt Steamship Company, parent company of theRoosevelt Line, in 1931 to formRoosevelt International Mercantile Marine Company (RIMM).[28] Later in 1931, RIMM acquired the financially troubledUnited States Lines and began consolidating its operations under that brand. TheAtlantic Transport Line was dissolved in late 1931 and its ships were distributed throughout RIMM's remaining divisions.[29][30]
TheAmerican Line was merged into United States Lines in 1932, the Red Star Line was sold toArnold Bernstein in 1934,Baltimore Mail Line merged into United States Lines in 1937, thePanama Pacific Line was dissolved in 1938 and its ships divested, andAmerican Merchant Line was merged into United States Lines in 1938.[29][30]
Finally, the Roosevelt Line was merged into United States Lines in 1940, leaving that company as RIMM's only remaining business. RIMM changed its name to United States Lines Inc. in 1943, recasting itself as a smaller company focused exclusively on transatlantic routes under a single brand.[29][30]
Some businesses of the modern shipping industry still regard IMM as an early attempt at the corporate ownership of several companies under a single trust; the kind of large overseeing companies that dominate much of the maritime shipping world today.[citation needed]
Company became United States Lines Inc, 1943[32]
