The United Kingdom at home

The Kingdom of Great Britain comes into being under the Treaty of Union of the kingdoms of England (which then included Wales) and Scotland on 1 May 1707. A Treaty of Union then unites the kingdoms of Great Britain and Ireland in 1801. The Great Famine of 1845–52 is contributory to the formation of the Irish Free State comprising the twenty-six southern counties of Ireland that vote to secede from the United Kingdom in 1922. The six counties of Northern Ireland, however, vote to remain as part of the United Kingdom of Great Britain and Northern Ireland.
