International Mercantile Marine Company, 1923

Categories: ,


The International Mercantile Marine Company, originally International Navigation Company (1871), known as IMM, was a trust company formed by JP Morgan to try to control the maritime trade in the Atlantic.

The IMM was the result of the merger of several transatlantic lines:

– American Line
– Red Star Line
– Atlantic Transport Line
– White Star Line
– Leyland Line
– Dominion Line

In 1900 JP Morgan had already concluded negotiations with Clement Griscom, president of the INC, that operated the Red Star Line and the American Line. In December of that year the Atlantic Transport Line joined the INC and in April 1901 the Leyland Line also. Later, in April 1902, the White Star Line also joined, forming thus the new International Mercantile Marine, that was incorporated in New Jersey that year.

As a consequence of the creation of the IMM, the english company Cunard Lines received grants from the British Government to build two new great liners, the Lusitania and the Mauretania. The IMM responded by building the RMS Olympic, RMS Titanic and the HMHS Britannic.

On April 15th 1912 the RMS Titanic, the ‘crown jewel’ of the fleet, sank in its maiden voyage. This tragedy, together with the existing financial problems and that the company was not meeting its expectations of controlling the trade on the Atlantic, resulted in bankruptcy in 1915. Although the company manage to survive until 1931, it was then acquired by the Roosevelt Steamship Company
