The English Civil Wars (1642-1651) stemmed from conflict between Charles I and Parliament over an Irish insurrection. The first war was settled with Oliver Cromwell’s victory for Parliamentary forces at the 1645 Battle of Naseby. The second phase ended with Charles’ defeat at the Battle of Preston and his subsequent execution in 1649. Charles’ son, Charles, then formed an army of English and Scottish Royalists, which prompted Cromwell to invade Scotland in 1650. The following year, Cromwell shattered the remaining Royalist forces and ended the “wars of the three kingdoms,” though Charles II eventually ascended to the throne in 1660.
