United Kingdom The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK)[14] or Britain,[note 10] is a sovereign country lying off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands.[15] Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state‍—‌the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of 242,500 square kilometres (93,600 sq mi), the United Kingdom is the 78th-largest sovereign state in the world. It is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017.
Wikipedia:Nationality of people from the United Kingdom Under British law, these four countries are an equal union, sharing a common British citizenship. The term "Britain" here means "the United Kingdom of Great Britain and Northern Ireland". A UK passport describes its holder as a "British citizen". According to British nationality law all citizens of the UK have British nationality.[2] This has been so since the Acts of Union 1707,[3] in which, after negotiations for a union treaty ended in July 1706, the acts were ratified by both the parliaments of England and Scotland.[4] "Great Britain" strictly speaking means the island comprising England, Scotland and Wales, and thus does not include Northern Ireland, so it is not the same as "Britain".
