 Various forms of Protestantism developed from the ferment of the English Civil War onwards.The Quakers (formally, the Religious Society of Friends) were founded by George Fox in the 1640s.Following the Great Ejection of 1662, about a tenth of Church of England ministers gave up their livings, and many of them contributed to various forms of Rational Dissent which evolved via English Presbyterianism into, among others, Unitarianism, which still has more than 100 congregations in the 21st century.
