In 1642, long-simmering tensions finally boiled over into war in England as King Charles I raised an army against his own parliament to reestablish his authority in his kingdom. The division between them was largely religious, as Charles was inclined toward tolerance of all Christian religions, while his parliament was full of Protestant “Puritans” who wanted to purge England of any Catholic elements. In the resulting English Civil War, Charles's forces were eventually routed, and the king was captured by Puritan forces. However, Charles escaped once and rallied his forces to take on the parliamentary army a second time. Since it had become obvious that Charles could not be trusted under any capacity to abide by any agreement he made for peace, religion, or political power, the House of Commons put him on trial before a specially appointed High Court of Justice in January 1649. Charles was convicted of treason and sentenced to be executed on January 30, 1649.
