The main cause of the English Civil War in 1642 was the never-ending argument between King Charles X and the Parliament. King Charles was bold and obnoxious and stuck-up which eventually lead to his death. Both parties had their own ways of thinking/basic truths/rules about religion and money. During the heat of discussions, King Charles never listened and made decisions all by himself, which seemed like he was ruling out the powers of Parliament.
This crack (or argument) between the King and the Parliament resulted to a war that divided the country. King Charles X's famous enemy in government was Oliver Cromwell, one of the people who signed his death warrant in the year 1649.
