Formed in 1872 as the American Steamship Co., Philadelphia and commenced passenger and cargo services to Queenstown and Liverpool, mostly with chartered ships. By 1884 passenger traffic on the North Atlantic had fallen and trade to Philadelphia decreased dramatically and the International Navigation Co of Philadelphia (Red Star Line) acquired the company. In 1892 an Act of Congress ensured that two large vessels of the British flagged Inman Line (owned by International Navigation Co) were transferred to the U.S. flag under the title of American Line. The parent company, International Navigation Co changed it's name in 1902 to International Mercantile Marine Co and purchased the share capitals of White Star, Dominion, Atlantic Transport and Leyland Lines as well as owning Red Star Line. Subsequent history of the company is covered by Red Star Line.
