The Clarendonians were a group of English supporters of King Charles I during the English Civil War in the 17th century. They were named after the Clarendon area in England and were known for their loyalty to the monarchy. The Clarendonians opposed the Parliamentarians, who sought to limit the king's power and establish a more democratic government. This group played a significant role in the conflict, advocating for royalist principles and supporting the king's authority. Their efforts were part of a larger struggle between royalists and parliamentarians, which ultimately led to the establishment of the Commonwealth of England under Oliver Cromwell.
