European Free-Churches left established and state churches in Europe over the belief that congregational activity and membership should be voluntary and free of state control. Examples of these churches include the Society of Friends (Quakers), various Mennonite churches and the Evangelical Covenant Church, which is the result of a schism from the Church of Sweden in the 19th century.
