Charles I (1600-1649) was King of England, Scotland and Ireland from 1625 until his execution. His conflicts with Parliament over royal prerogative, taxation, and religion drove the three English Civil Wars. James Stanley, 7th Earl of Derby, was among his most committed supporters, and the Isle of Man remained a Royalist stronghold until 1651, two years after the King's death. Charles was tried by a High Court of Justice and executed at Whitehall on 30 January 1649.
