Non-Anglicans refer to individuals or groups who do not belong to the Anglican Church, a branch of Christianity that emerged from the Church of England. This term encompasses a variety of religious denominations, including Catholics, Puritans, Baptists, and Quakers, each with distinct beliefs and practices. During the English Civil War and the Glorious Revolution, Non-Anglicans played a crucial role in challenging the established Church of England and advocating for religious tolerance and reform.
