P&O Princess Cruises plc was formed in 2000, following the demerger of the cruise ship division of the P&O group. Originating as the Peninsular and Oriental Steam Navigation Company in England in 1837, P&O operated the world's first commercial cruise ships. Restructuring of the P&O group in the 20th century led to its cruise operations being rebranded as P&O Cruises and P&O Cruises Australia, with the company acquiring Princess Cruises in 1974. Following the demerger in 2000, the company also acquired AIDA Cruises, as well as establishing the A'Rosa Cruises and Ocean Village brands.
