The Cunard Line (, KEW-nard) is a British shipping company and an international cruise line based at Carnival House at Southampton, England, operated by Carnival UK and owned by Carnival Corporation. Since 2011, Cunard and its four ships have been registered in Hamilton, Bermuda.
In 1839, Samuel Cunard was awarded the first British transatlantic steamship mail contract, and the next year formed the British and North American Royal Mail Steam-Packet Company in Glasgow with shipowner Sir George Burns together with Robert Napier, the famous Scottish steamship engine designer and builder, to operate the line's four pioneer paddle steamers on the Liverpool–Halifax–Boston route. For most of the next 30 years, Cunard held the Blue Riband for the fastest Atlantic voyage. However, in the 1870s Cunard fell behind its rivals, the White Star Line and the Inman Line. To meet this competition, in 1879 the firm was reorganised as the Cunard Steamship Company Ltd, to raise capital.
In 1902, White Star joined the American-owned International Mercantile Marine Co. In response, the British Government provided Cunard with substantial loans and a subsidy to build two superliners needed to retain Britain's competitive position. Mauretania held the Blue Riband from 1909 to 1929. Her sister ship, Lusitania, was torpedoed in 1915 during the First World War.
In 1919, Cunard relocated its British homeport from Liverpool to Southampton, to better cater for travellers from London. In the late 1920s, Cunard faced new competition when the Germans, Italians and French built large prestige liners. Cunard was forced to suspend construction on its own new superliner because of the Great Depression. In 1934, the British Government offered Cunard loans to finish Queen Mary and to build a second ship, Queen Elizabeth, on the condition that Cunard merge with the then-ailing White Star Line to form Cunard-White Star Line. Cunard owned two-thirds of the new company. Cunard purchased White Star's share in 1947; the name reverted to the Cunard Line in 1950.
Upon the end of the Second World War, Cunard regained its position as the largest Atlantic passenger line. By the mid-1950s, it operated 12 ships to the United States and Canada. After 1958, transatlantic passenger ships became increasingly unprofitable because of the introduction of jet airliners. Cunard undertook a brief foray into air travel via the "Cunard Eagle" and "BOAC Cunard" airlines, but withdrew from the airline market in 1966. Cunard withdrew from its year-round service in 1968 to concentrate on cruising and summer transatlantic voyages for holiday makers. The Queens were replaced by Queen Elizabeth 2 (QE2), which was designed for the dual role.
In 1998, Cunard was acquired by the Carnival Corporation, and accounted for 8.7% of that company's revenue in 2012. In 2004, QE2 was replaced on the transatlantic runs by Queen Mary 2 (QM2). The line also operates Queen Victoria (QV), Queen Elizabeth (QE) and Queen Anne (QA). As of 2025, Cunard is the only shipping company to still operate a scheduled passenger service between Europe and North America.
The British Government started operating monthly mail brigs from Falmouth, Cornwall, to New York in 1756. These ships carried few non-governmental passengers and no cargo. In 1818, the Black Ball Line opened a regularly scheduled New York–Liverpool service with clipper ships, beginning an era when American sailing packets dominated the North Atlantic saloon-passenger trade that lasted until the introduction of steamships. A Committee of Parliament decided in 1836 that to become more competitive, the mail packets operated by the Post Office should be replaced by private shipping companies. The Admiralty assumed responsibility for managing the contracts. The famed Arctic explorer Admiral Sir William Edward Parry was appointed as Comptroller of Steam Machinery and Packet Service in April 1837. Nova Scotians led by their young Assembly Speaker, Joseph Howe, lobbied for steam service to Halifax. On his arrival in London in May 1838, Howe discussed the enterprise with his fellow Nova Scotian Samuel Cunard (1787–1865), a shipowner who was also visiting London on business. Cunard and Howe were associates and Howe also owed Cunard £300 (equivalent to £28,755 in 2025). Cunard returned to Halifax to raise capital, and Howe continued to lobby the British government. The Rebellions of 1837–1838 were ongoing and London realised that the proposed Halifax service was also important for the military.
That November, Parry released a tender for North Atlantic monthly mail service to Halifax beginning in April 1839 using steamships with 300 horsepower. The Great Western Steamship Company, which had opened its pioneer Bristol–New York service earlier that year, bid £45,000 for a monthly Bristol–Halifax–New York service using three ships of 450 horsepower. While British American, the other pioneer transatlantic steamship company, did not submit a tender, the St George Steam Packet Company, owner of Sirius, bid £45,000 for a monthly Cork–Halifax service and £65,000 for a monthly Cork–Halifax–New York service. The Admiralty rejected both tenders because neither bid offered to begin services early enough.
Cunard, who was back in Halifax, did not know of the tender until after the deadline. He returned to London and started negotiations with Admiral Parry, who was Cunard's good friend from when Parry was a young officer stationed in Halifax 20 years earlier. Cunard offered Parry a fortnightly service beginning in May 1840. While Cunard did not then own a steamship, he had been an investor in an earlier steamship venture, Royal William, and owned coal mines in Nova Scotia. Cunard's major backer was Robert Napier whose Robert Napier and Sons was the Royal Navy's supplier of steam engines. He also had the strong backing of Nova Scotian political leaders at the time when London needed to rebuild support in British North America after the rebellion.
Over Great Western's protests, in May 1839 Parry accepted Cunard's tender of £55,000 for a three-ship Liverpool–Halifax service with an extension to Boston and a supplementary service to Montreal. The annual subsidy was later raised £81,000 to add a fourth ship and departures from Liverpool were to be monthly during the winter and fortnightly for the rest of the year. Parliament investigated Great Western's complaints, and upheld the Admiralty's decision. Napier and Cunard recruited other investors including businessmen James Donaldson, Sir George Burns, and David MacIver. In May 1840, just before the first ship was ready, they formed the British and North American Royal Mail Steam Packet Company with initial capital of £270,000, later increased to £300,000 (£26,423,872 in 2025). Cunard supplied £55,000. Burns supervised ship construction, MacIver was responsible for day-to-day operations, and Cunard was the "first among equals" in the management structure. When MacIver died in 1845, his younger brother Charles assumed his responsibilities for the next 35 years. (For more detail of the first investors in the Cunard Line and also the early life of Charles MacIver, see Liverpool Nautical Research Society's Second Merseyside Maritime History, pp. 33–37 1991.)
In May 1840 the coastal paddle steamer Unicorn made the company's first voyage to Halifax to begin the supplementary service to Montreal. Two months later the first of the four ocean-going steamers of the Britannia Class, departed Liverpool. By coincidence, the steamer's departure had patriotic significance on both sides of the Atlantic: she was named Britannia, and sailed on 4 July. Even on her maiden voyage, however, her performance indicated that the new era she heralded would be much more beneficial for Britain than the US. At a time when the typical packet ship might take several weeks to cross the Atlantic, Britannia reached Halifax in 12 days and 10 hours, averaging 8.5 knots (15.7 km/h), before proceeding to Boston. Such relatively brisk crossings quickly became the norm for the Cunard Line: during 1840–41, mean Liverpool–Halifax times for the quartet were 13 days 6 hours to Halifax and 11 days 4 hours homeward. Two larger ships were quickly ordered, one to replace the Columbia, which sank at Seal Island, Nova Scotia, in 1843 without loss of life. By 1845, steamship lines led by Cunard carried more saloon passengers than the sailing packets. Three years later, the British Government increased the annual subsidy to £156,000 so that Cunard could double its frequency. Four additional wooden paddlers were ordered and alternate sailings were direct to New York instead of the Halifax–Boston route. The sailing packet lines were now reduced to the immigrant trade.
