The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain,[m] is a country in Northwestern Europe, off the coast of the continental mainland. It comprises England, Scotland, Wales, and Northern Ireland.[n] The UK includes the island of Great Britain, the north-eastern part of the island of Ireland, and most of the smaller islands within the British Isles, covering 94,354 square miles (244,376 km2).[f] Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea, and the Irish Sea. The United Kingdom had an estimated population of 68.2 million people in 2023. The capital and largest city of both England and the United Kingdom is London, whose wider metropolitan area is the largest in Western Europe, with a population of 14.9 million. The cities of Edinburgh, Cardiff, and Belfast are the national capitals of Scotland, Wales, and Northern Ireland, respectively.
The UK has been inhabited continuously since the Neolithic. In AD 43, the Roman conquest of Britain began; the Roman departure was followed by Anglo-Saxon settlement. In 1066, the Normans conquered England. With the end of the Wars of the Roses, the English state stabilised and began to grow in power, resulting by the 16th century in the annexation of Wales, and the establishment of the British Empire. Over the course of the 17th century, the role of the British monarchy was reduced, particularly as a result of the English Civil War. In 1707, the Kingdom of England and the Kingdom of Scotland united under the Treaty of Union to create the Kingdom of Great Britain. In the Georgian era, the office of prime minister became established. The Acts of Union 1800 incorporated the Kingdom of Ireland to create the United Kingdom of Great Britain and Ireland in 1801. Most of Ireland seceded from the UK in 1922 as the Irish Free State, and the Royal and Parliamentary Titles Act 1927 created the present United Kingdom.
