The British Isles have a rich history going back thousands of years.The history of the United Kingdom as a unified sovereign state began with the political union of the kingdoms of England, which included Wales, and Scotland on 1 May 1707 in accordance with the Treaty of Union, signed on 22 July 1706,[1] and ratified by both the Parliaments of England and Scotland each passing an Act of Union. The Union created the Kingdom of Great Britain,[2] which shared a single constitutional monarch and a single parliament at Westminster.
In 1922 and following the Anglo-Irish Treaty, Ireland seceded from the United Kingdom of Great Britain and Ireland to become the Irish Free State[5], a dominion of the British Empire but a day later, Northern Ireland seceded from the Free State and rejoined the United Kingdom. As a result, in 1927 the United Kingdom changed its formal title to the “United Kingdom of Great Britain and Northern Ireland,”[6] usually shortened to the “United Kingdom”, the “UK” or “Britain”, but the Monarch remained “By the Grace of God, of Great Britain, Ireland and the British Dominions beyond the Seas King/Queen, Defender of the Faith” until 1953.United Kingdom remains a strong economic, cultural, military and political influence in the 21st century.
