The emergence of the Cavaliers
However far back into history one may postulate the origins of the English Civil War, the actual development of hostilities was extremely rapid. A civil war became physically possible only in March 1642, when Charles the First left a London dominated by his opponents to set up headquarters at York and attract supporters. In June he felt ready to call the country to arms and by August two rival armies were actually gathering and marching. The most serious of all divisions of the English people had occurred in a mere five months.
