Elizabeth II undertook a number of state and official visits over her 70-year reign (1952 to 2022), as well as trips throughout the Commonwealth, making her the most widely travelled head of state in history. She did not require a British passport for travelling overseas, as all British passports were issued in her name. Elizabeth II was the sovereign of more than one independent state and represented both Canada and the United Kingdom on state visits, though the former on just two occasions. The relevant governor-general usually carried out state visits on the Queen's behalf.
