Hapag-Lloyd AG is a German international shipping and container transportation company. It was formed in 1970 through a merger of Hamburg-American Line (HAPAG) and Norddeutscher Lloyd. The company was formed on September 1, 1970, by the merger of two German transportation/maritime companies, Hamburg-American Line (HAPAG), founded in 1847, and Norddeutscher Lloyd (known in English as North German Lloyd), which was formed in 1857. Since its formation, Hapag-Lloyd has seen changes among its shareholders and has also undergone a number of mergers with other companies. For instance, Hapag-Lloyd was completely acquired by, and became a subsidiary of TUI AG (Hanover) in 1998. This transition was followed by TUI selling a majority stake of Hapag-Lloyd to private investors in Hamburg in 2009 and further sales in 2012. Other important events in the history of the company include Hapag-Lloyd's acquisition of CP Ships in 2005 as well as Hapag-Lloyd's merger with the container business of CSAV in 2014, and United Arab Shipping Company in 2017. Hamburg America Line The Hamburg-Amerikanische Packetfahrt-Aktien-Gesellschaft for shipping across the Atlantic Ocean was founded in Hamburg. In 1912, Hapag built the first of their "Big Three" ocean liners; the Imperator, followed by its twin Vaterland. A third twin, Bismarck, was under construction at the outbreak of World War I and was completed after the war for White Star Line as the Majestic. These were the first liners to exceed 50,000 gross tons and 900 feet (274 m) in length. During World War I, the majority of Hapag's fleet of 175 ships were wiped out, and most of the surviving ships (including the "Big Three") had to be turned over to the winning side as war reparations. After the war's end, Hapag rebuilt its fleet with much smaller ships than before the war, but their fleet was again mostly wiped out during World War II, and the surviving ships turned over to Allied powers.
