Founded in 1840 by Samuel Cunard (originally British and North American Royal Mail Steam Packet Company) to operate the first regular steam mail service across the North Atlantic, between Liverpool and Boston/Halifax.4 Quickly became one of the most prestigious lines, known for safety and regularity, although initially not focusing on speed or extreme luxury.4 Operated iconic ships such as Britannia (first ship), Persia (first iron ship), Servia (first steel ship), Campania and Lucania (first with twin propellers and holders of the Blue Riband), Mauretania (1906, holder of the Blue Riband for 22 years), Lusitania (sunk in 1915), Aquitania, and the famous "Queens": Queen Mary and Queen Elizabeth (launched in the 1930s).4 Maintained an intense rivalry with the White Star Line and other companies (Inman, Guion, HAPAG, NDL) for supremacy in the North Atlantic.31 In 1934, during the Great Depression and with British government support, merged with its main rival, the White Star Line, forming the Cunard-White Star Line (until 1949, when it reverted to Cunard Line).29 Played a vital role in transporting troops and materiel during the World Wars.4 The company continued to operate after 1950, adapting to the jet age with a focus on cruises.
