The history of local government in the United Kingdom covers the development of local government in the United Kingdom since its formation in 1707.^[1] Each of the four countries of the United Kingdom has a separate system of local government with origins that predate the UK itself. Little changed until the 19th century after which each system experienced a constant evolution of organisation and function. Following devolution at the end of the 20th century, the Scottish Parliament exercises power over local government in Scotland, the Northern Ireland Assembly exercises power over local government in Northern Ireland, the Welsh Assembly exercises power over local government in Wales and the UK Parliament continues to exercise power over local government in England.
