When did the English Civil War begin?

The first military action (of sorts) took place at Hull in January 1642, which refused to admit Charles I or his troops into the city. In August 1642 Charles I 'raised his standard') at Nottingham (in other words, called on all loyal subjects to fight for him). By then, there was already widespread fighting at local level. The first major battle is generally given as the Battle of Powick Bridge (Worcestershire) on 23 September 1642. This was followed in October by the first well known battle - Edge Hill.
