P&O Cruises is a British cruise line based in Southampton, but its history has two distinct starting points. The present-day cruise subsidiary was founded in 1977. The passenger-shipping tradition it inherited began in 1837, when the Peninsular Steam Navigation Company started carrying mail and passengers between England and the Iberian Peninsula. In 1844, P&O expanded passenger travel to include leisure cruises to the Mediterranean. Distinguishing the modern company from its predecessor matters: this is a long inheritance, not an unchanged business operating under the same name for nearly two centuries.
From mail routes to leisure cruising
The Peninsular Steam Navigation Company grew out of an association formed by London shipbroker Brodie McGhie Willcox, Shetland sailor Arthur Anderson and Dublin steamship owner Richard Bourne. In 1837, the company won a contract to transport mail and began carrying passengers between England and the Iberian Peninsula. In 1840, it merged with the Transatlantic Steam Ship Company, expanded its operations towards the Orient and became the Peninsular and Oriental Steam Navigation Company, known as P&O.
In 1844, P&O began leisure sailings from England to the Mediterranean. These were among the first cruises of their kind: the journey itself, rather than simply arrival at a destination, became part of the holiday. The early cruises establish an important chapter in passenger travel, but they belonged to P&O’s nineteenth-century operations, not the modern cruise subsidiary.
As air travel became more affordable in the mid-twentieth century, passenger shipping faced a changing market. In the 1970s, P&O dedicated its passenger operations entirely to leisure cruising and established P&O Cruises as a subsidiary in 1977. Its first ships had already served the parent company. Oriana and Canberra operated from Southampton, Arcadia served the Australian market from Sydney, and Uganda ran educational cruises.
A cruise line takes shape
The early fleet shifted between routes and markets. Arcadia left the Australian fleet in 1979 and was replaced by Sea Princess. Oriana moved to Australia in 1981; Sea Princess transferred to the UK market the following year. In 1982, the Falklands War brought a sudden change of purpose: Canberra was requisitioned as a troopship and Uganda as a hospital ship. Uganda left the fleet in 1983, followed by Oriana and Sea Princess in 1986.
P&O separated its Australian and UK operations in 1988. The acquisition of Sitmar Cruises later contributed to the formation of P&O Cruises Australia, while P&O Cruises focused on the UK market. In 1995, the second Oriana entered service as the UK operation’s first newbuild. Unlike the older liners inherited from P&O, which had been designed to transport passengers between places, this ship was built specifically for pleasure cruising.
Ownership changed in the early 2000s. P&O divested its cruise operations in 2000, transferring them to the independent company P&O Princess Cruises. In 2003, P&O Princess merged with Carnival Corporation to form Carnival Corporation & plc. P&O Cruises became part of the wider Carnival group, while remaining a named cruise line based in Southampton at Carnival House.
New ships, old name
Fleet development continued with Ventura, which entered service in 2008, and its sister ship Azura in 2010. In 2012, the line marked the 175th anniversary of the Peninsular Steam Navigation Company by gathering its seven ships in Southampton: Adonia, Arcadia, Aurora, Azura, Oceana, Oriana and Ventura. The anniversary connected the modern fleet to the history of the predecessor company without erasing the distinction between them.
A livery based on the Union Jack was introduced in 2014 to emphasise the line’s British heritage. Britannia entered service in 2015. Although the original article described Britannia as the largest ship in the fleet, the supplied fleet information lists both Iona and Arvia as larger. P&O Cruises’ fleet has continued to change: Adonia transferred to Carnival’s Fathom brand in 2016, returned to P&O Cruises and departed permanently in 2018; Oriana left in 2019.
In March 2020, P&O Cruises suspended passenger operations as cruise lines worldwide responded to the COVID-19 pandemic. Oceana left the fleet that July, as Carnival sold older ships across its fleets to increase liquidity. Iona joined in October 2020, but its maiden voyage was delayed until passenger operations resumed in June 2021. Arvia, its sister ship, followed in 2022.
Iona was the first ship built for the British market to be powered by liquefied natural gas (LNG) rather than fuel oil. The supplied reference describes this as an effort to make the ship more environmentally friendly; it does not establish wider claims about the company’s environmental performance. The line’s fleet also includes Aurora, Arcadia, Ventura, Azura and Britannia. P&O Cruises and P&O Ferries are separate businesses: after P&O Ferries dismissed staff in 2022, P&O Cruises faced public backlash and used advertising to clarify their separate ownership.
What the British connection means
The company’s British connection is grounded in its Southampton base, its focus on the UK market and its historical inheritance from P&O’s English passenger routes. Its story also reaches beyond Britain: early services extended from the Iberian Peninsula towards the Orient, and the cruise operation once served both UK and Australian markets. The Union Jack-based livery introduced in 2014 made its British association especially visible, while the modern fleet reflects a business shaped by changing travel habits, corporate ownership and the shift from transport liners to ships designed for leisure.
That history is more complicated than a simple tale of continuous growth. Ships were moved between markets, requisitioned during the Falklands War, replaced or transferred, and affected by the pandemic suspension. Ownership also moved from P&O to P&O Princess Cruises and then into the Carnival group. The cruise line’s identity has endured through these changes, but the history is best understood as a sequence of related operations rather than a single company unchanged since 1837.
Why P&O Cruises deserves a place in British Legacy
P&O Cruises deserves a place in British Legacy because its history records a substantial change in passenger travel. The tradition began with mail and passenger services between England and the Iberian Peninsula in 1837. In 1844, P&O extended its passenger operations to Mediterranean leisure sailings, making the voyage itself part of the experience. The modern cruise subsidiary was founded in 1977, when P&O’s passenger operations became focused entirely on leisure cruising. Keeping those milestones distinct gives the story its proper scale: a nineteenth-century shipping inheritance carried forward by a modern company, rather than a claim that the present-day cruise line has existed unchanged for nearly two centuries.
Its later history helps explain how British passenger shipping adapted. The UK operation separated from its Australian counterpart, passed through changes of corporate ownership and invested in vessels built specifically for cruising. Southampton remains its base; the Union Jack livery and ships built for the British market make the national connection explicit. The fleet’s record also reflects events beyond the business of holidays, from the requisitioning of Canberra and Uganda during the Falklands War to the worldwide interruption of cruise operations in 2020. Iona’s LNG propulsion is a specific design choice, not proof of sweeping environmental achievement. Together, these details make P&O Cruises a useful part of British Legacy: a recognisable UK-based line whose changing ships, routes and ownership show how a long passenger-shipping tradition has been reshaped for modern leisure travel.
