In England, a civil parish is a type of administrative parish used for local government. It is a territorial designation which is the lowest tier of local government. Civil parishes can trace their origin to the ancient system of parishes, which for centuries were the principal unit of secular and religious administration in most of England and Wales. Civil and religious parishes were formally split into two types in the 19th century and are now entirely separate. Civil parishes in their modern form came into being through the Local Government Act 1894, which established elected parish councils to take on the secular functions of the parish vestry.
