AIDA Cruises originated from the state-owned German shipping conglomerate Deutsche Seereederei, established in Rostock, Germany, in 1952.[32] The company entered the passenger market in the 1960s, but after the unification of Germany in 1990, the company was privatised and its passenger ships acquired by Deutsche Seetouristik. In 1996, the company launched its first new cruise ship AIDA, but after failing to achieve a profit, the ship was sold to Norwegian Cruise Line, continuing operations under a charter agreement.[32] In 1999, Deutsche Seetouristik was acquired by British shipping company P&O, with the AIDA name being repurchased from NCL. P&O subsequently formed AIDA Cruises as a subsidiary brand, with two new ships ordered to form a fleet. AIDA was renamed AIDAcara, with AIDAvita and AIDAaura launched in 2002 and 2003 respectively.[32]

Carnival Cruise Line was founded in 1972 as a subsidiary of American International Travel Service (AITS), by Ted Arison and Meshulam Riklis.[3] Due to mounting debts, Riklis sold his stake in the company to Arison for $1 in 1974. However through the acquisition of existing ships, the company continued to grow and, in 1980, Carnival ordered its first new commission, the Tropicale, which was completed in 1981/2.[3] Three further ships were commissioned during the 1980s, the Holiday (1985), Jubilee (1986) and Celebration (1987). In 1987, Carnival completed an initial public offering of 20 percent of its common stock on the New York Stock Exchange, raising approximately $400m in capital.[3] The capital raised was used to finance acquisitions, so in 1993 the business was restructured as a holding company, under the name Carnival Corporation, with Carnival Cruise Line becoming its principal subsidiary.[3]

Costa Cruises originates from a cargo shipping company founded by Giacomo Costa fu Andrea in Genoa, Italy in 1854.[33] Better known as Costa Line or C Line by the 1920s, its first passenger carrier was Maria C, a former U.S. Navy stores ship that was partly converted for passenger use and served various routes to North and South America from 1947 to 1953.[33] The company's first dedicated passenger ship was the Anna C, a cargo vessel that was requisitioned for war time use by the Royal Navy and refitted as an accommodation ship before returning to merchant use.[33] Costa purchased the ship in 1947 and it operated between Italy and South America from 1948, later converting to full-time cruising and serving with the company until 1971. From the late 1960s until the 1980s, Costa rapidly developed its passenger operations into what we now recognise as modern cruise ships. Subsequently, in 1987, it consolidated its cruise ship operations into a new company, Costa Cruises, which at its peak, was the largest cruise ship operator in the world. The takeover of Costa Cruises by Carnival Corporation began in 1997, as a 50/50 deal between Carnival and the British tour operator Airtours.[34] On 13 January 2012, Costa Concordia, a ship operated by the line, hit an underwater rock and ran aground in Isola del Giglio, Tuscany, resulting in 32 deaths. Investigations proved that the captain and general bad organization was responsible for the disaster, and the company was fined.[35]

CSSC Carnival Cruise Shipping (Carnival China) is a Chinese-American cruise line that is scheduled to begin operation in 2019. CSSC Carnival was founded in October 2015 as a joint venture, worth about $4 billion over ten years, between American cruise line Carnival Corporation & plc, Chinese sovereign wealth fund China Investment Corporation, and Chinese shipbuilder China State Shipbuilding Corporation (CSSC). CSSC Carnival is headquartered in Hong Kong and is majority owned by the Chinese shareholders, which collectively own 60% of the company, with Carnival holding the remainder.[18]

The second oldest brand in the Carnival group after P&O, Cunard Line originated in 1840 and celebrated its 179th anniversary in 2019. It was founded by Samuel Cunard, who was awarded the first trans-Atlantic mail contract in 1837 and established the British and North American Royal Mail Steam-Packet Company in 1840.[36] After initially dominating the trans-Atlantic route, the need for new capital led to the company being re-organised as the Cunard Steamship Company Ltd in 1879.[37] The early 1900s saw increased competition for speed, particularly from Germany, which led the British government to subsidise the building of Mauretania and Lusitania, which both won the Blue Riband. Competition continued to increase however and by the early 1930s, Cunard was experiencing financial difficulties.[38] To secure further government subsidy, it agreed to merge with its chief rival White Star Line, to form Cunard-White Star Line in 1934.[39] Cunard later purchased the remaining White Star shares in 1947, reverting to the name Cunard Line in 1949. Cunard continued to operate independently until 1971, when it was acquired by the conglomerate Trafalgar House, which was in turn taken over by the Norwegian company Kværner in 1996.[40] In 1998, Carnival Corporation purchased a controlling stake in Cunard, completing the acquisition in 1999 to become sole shareholder.[41] Since that time, Cunard has been one of Carnival's most high-profile brands, with the continued popularity of the famous Queen Elizabeth 2 and the development of the world's largest trans-Atlantic Ocean liner Queen Mary 2, which continues to be the flagship of the fleet.[42]

Holland America Line originated as Plate, Reuchlin & Company, founded in Rotterdam, Netherlands, in 1871. Initially struggling to survive, the company went public in 1873, renamed Nederlandsch Amerikaansche Stoomvaart Maatschappij (NASM).[43] The company grew quickly in the early years, acquiring several new ships, including SS Rotterdam, which operated the company's first passenger cruise in 1895. The company also quickly became known by its shortened English name, Holland America Line, which was officially adopted in 1869. By the early 1900s, the company had separated its cargo and passenger operations, with its passenger ships being identifiable by names ending with dam, a tradition which continues with Holland America cruise ships today. The development of container shipping in the 1960s, forced the company to make a decision between investing in new cargo ships, or cruise ships. It ultimately sold its cargo operations, becoming exclusively a cruise ship company in 1973.[43] Holland America continued to thrive well into the 1980s, consolidating its business with the acquisitions of Westours, Windstar Cruises and Home Lines. In 1989 however, it was itself the subject of an acquisition, when it was purchased in full by Carnival Corporation.[43]

P&O Cruises was originally a subsidiary of the British shipping company P&O and was founded during a restructuring of P&O's operations in 1977.[44] Along with P&O Cruises Australia, a sister company also founded by P&O, it has the oldest heritage of any cruise line in the world, dating to P&O's first passenger operations in 1837.[45][46][47] P&O Cruises was divested from P&O in 2000, becoming a subsidiary of P&O Princess Cruises,[48] before coming under the ownership of Carnival Corporation & plc in 2003, following the merger between P&O Princess Cruises and Carnival Corporation. At the time P&O Cruises and Princess Cruises demerged with Princess Cruises moving to the Corporation side and Cunard merging with P&O cruises to make Carnival UK.[2] P&O Cruises is based in Southampton, England, and operates a fleet of six ships, dedicated to serving the British market.[49]
