Overview
P&O, formally the Peninsular and Oriental Steam Navigation Company, is a historic British shipping and transport brand with origins in an 1822 partnership between London shipbroker Brodie McGhie Willcox and Shetland sailor Arthur Anderson. Captain Richard Bourne joined the enterprise in 1835, when the partners established a regular steamship service between Britain and the Iberian Peninsula. The business adopted the name Peninsular Steam Navigation Company and received a British Admiralty mail contract in 1837. A royal charter in 1840 created the Peninsular and Oriental Steam Navigation Company, giving the company the name and institutional identity that later became widely known as P&O. Mail carriage was central to P&O's early prosperity. Its routes expanded from Spain and Portugal to Alexandria, Egypt, and later to Brindisi and destinations across the Mediterranean, the Middle East and Asia. The company also carried passengers and developed early leisure voyages, including Mediterranean cruises from Southampton in 1844. During the nineteenth century, P&O became associated with long-distance passenger liners, imperial mail routes and commercial shipping. Its historical activities also included the transportation of opium from India to China after 1847, a trade that forms part of the less celebratory history of the company and of British maritime commerce in that period. P&O expanded substantially during the twentieth century. It acquired British India Steam Navigation in 1914, gained control of the Orient Line in 1918 and reached a fleet of almost 500 vessels in the mid-1920s. Its ships served passenger, mail, cargo and commercial routes, while wartime losses were severe: 85 P&O ships were lost during the First World War and 179 during the Second World War. After 1945, the company operated major passenger liners and carried European migrants to Australia under the assisted-passage scheme commonly associated with the 'Ten Pound Poms'. As air travel became cheaper and faster, P&O shifted away from traditional liner services toward cruising, cargo, tankers and roll-on/roll-off ferries. The company diversified during the second half of the twentieth century. It absorbed British-India Steam Navigation in 1972, developed ferry operations in the Irish Sea and across the English Channel, and participated in the creation of Overseas Containers Limited in 1969. Its container business later became P&O Containers and was merged with Nedlloyd in 1996 to form P&O Nedlloyd. P&O also owned or invested in property, construction management, ports, cold logistics and other service businesses before refocusing on maritime and transport activities in 1999. P&O's modern corporate structure was shaped by a series of disposals. Its cruise division was separated in 2000 and subsequently combined with Carnival Corporation to create Carnival Corporation & plc in 2003; P&O Cruises remains a Carnival-operated brand under licence. P&O's container interests were sold to A.P. Moller-Maersk in 2005. In 2006, shareholders approved the acquisition of P&O by Dubai Ports World, now DP World, for approximately £3.9 billion. Following the acquisition, the P&O name continued across ferry, port, maritime logistics and heritage activities. P&O Ferries remains one of the most visible consumer-facing businesses, serving routes between Britain, France, the Netherlands, Belgium, Northern Ireland and Scotland. DP World also maintains P&O Heritage, an archive and collection devoted to the company's maritime history.
History
P&O began as a London-based shipping partnership formed in 1822 by Brodie McGhie Willcox and Arthur Anderson. Its initial business connected England with Spain and Portugal. In 1835, Captain Richard Bourne joined the enterprise, and the partners established a regular steamship service using the name Peninsular Steam Navigation Company. The company won a British Admiralty contract to carry mail to the Iberian Peninsula in 1837 and received a further contract for mail to Alexandria in 1840, the year in which it was incorporated by royal charter as the Peninsular and Oriental Steam Navigation Company. The company's early growth depended on mail contracts, but it also carried passengers and cargo. In 1844 it offered an early Mediterranean leisure cruise from Southampton, helping establish a model later developed by the modern cruise industry. Its network expanded through the Mediterranean and toward the Middle East and Asia. P&O's nineteenth-century commercial activities included the opium trade between India and China, a historically significant but controversial part of the company's record. During the first half of the twentieth century, P&O became one of Britain's largest shipping groups. It acquired British India Steam Navigation in 1914 and obtained a controlling interest in the Orient Line in 1918. Its fleet reached nearly 500 vessels in the 1920s. The company operated liners, mail steamers and cargo vessels, and suffered heavy wartime losses in both world wars. P&O also established a bank in 1920, later sold to Chartered Bank, and held interests in businesses connected with trade and distribution in the Middle East. After the Second World War, P&O operated large passenger liners on routes to Australia. The company carried many European migrants under assisted-passage arrangements and later pioneered cruising from Australia. The growth of commercial aviation, rising liner costs and changing travel patterns led to a strategic shift. P&O reduced its traditional liner operations, concentrated more heavily on cargo, entered the tanker sector in 1959 and developed roll-on/roll-off ferry services during the 1960s. P&O and Orient Line were formally combined in 1960, and the Orient identity disappeared from the fleet by 1966. Containerisation became another major turning point. In 1969, P&O joined British and Commonwealth Shipping, Furness Withy and the Ocean Steamship Company to establish Overseas Containers Limited. P&O later bought the remaining partners' interests and renamed the business P&O Containers. The container operation was merged with Nedlloyd in 1996, creating P&O Nedlloyd, in which P&O subsequently reduced and then sold its interest. Ferry operations also developed through Pandoro on the Irish Sea and P&O European Ferries after the acquisition of European Ferries in 1987. P&O diversified into construction management, property, ports, cold logistics, exhibition venues and other services during the late twentieth century. It later disposed of many non-core activities and announced a greater concentration on maritime and transport operations. The cruise business was separated in 2000, combined with Carnival Corporation in 2003 and became part of Carnival Corporation & plc. The container business was sold to A.P. Moller-Maersk in 2005. In 2006, P&O was acquired by Dubai Ports World, now DP World, after a contested process involving a competing bid from PSA International. The transaction prompted a major political dispute in the United States because P&O's port interests included terminal leases in New York, Newark, Baltimore, Miami, New Orleans and Philadelphia. DP World agreed to sell the American terminal operations later that year. Under DP World ownership, P&O continues as a group of maritime brands rather than as the former independently listed shipping conglomerate. P&O Ferries operates passenger and freight routes in European waters, while P&O-branded port, maritime logistics and heritage activities preserve parts of the company's commercial and historical identity.

Controversies
- 2006Political controversy over DP World's acquisitionControversy
The purchase of P&O by Dubai Ports World led to intense United States political debate over foreign ownership and port security. Critics focused on P&O terminal interests in several American ports, although the transaction did not transfer overall governmental control of those ports. DP World later agreed to sell the American terminal operations.
- 1987Herald of Free Enterprise disasterControversy
The roll-on/roll-off ferry Herald of Free Enterprise capsized off Zeebrugge on 6 March 1987, causing 193 deaths. The vessel was operated by Townsend Thoresen, which P&O had acquired. A public inquiry concluded that serious operational and managerial failures contributed to the disaster and described a pervasive organizational culture of negligence. Criminal charges against the company and seven employees did not produce convictions.
