This is a list of countries and territories formerly ruled or administered by the United Kingdom or part of the British Empire, with their independence days. Some countries did not gain their independence on a single date, therefore the latest day of independence is shown with a break down of dates further down.
Libya had been under the rule of the Ottoman Empire since the middle of the sixteenth century. Following the Italo-Turkish war of 1912, Libya became an Italian colony. With their defeat in World War II, the Italians lost control of Libya. The country came under UN administration. Control was split between France and Britain, with France administering the province Fezzan while the British administered the provinces of Cyrenaica and Tripolitania. In 1949, the UN General Assembly declared that Libya should become an independent country by 1 January 1952. On 24 December 1951, Libya declared its independence from France and Britain becoming the United Kingdom of Libya, a constitutional and hereditary monarchy under King Idris.
Anguilla declared independence from St Kitts and Nevis in 1967, following a revolution; in favour of returning to British authority in 1971 with full British Crown Colony status (renamed in 2002 as British Overseas Territory status) returning in 1980.
British Overseas Territories that have voted against another independent country sharing sovereignty over the territory with the British Crown
In the Northern Ireland sovereignty referendum, 1973, voters in Northern Ireland were asked to decide if they wanted to remain in the United Kingdom or to leave and join with the Republic of Ireland. They voted in favour of the United Kingdom by 98.9% to 1.1%, although Irish Republicans boycotted the vote.
Countries forming part of the United Kingdom that have voted not to be an independent country
In the Scottish independence referendum, 2014, 55.3% of voters who qualified as residents of Scotland, chose 'No' to the question: 'Should Scotland be an independent country?' 44.7% of voters chose 'Yes'. In March 2017, permission to run a second referendum was requested from Westminster by the Scottish Parliament, triggered by the Brexit vote, which saw a majority of voters in England and Wales vote to leave the EU while a majority in Scotland and Northern Ireland voted to remain.
