What factors led to the start of the English Civil Wars?

The English Civil War was in essence caused by the relationship between the country's King and its parliament, which had detoriorated over the previous decade. Charles has spent the 10 years running up to the war imposing a string of finacial and social measures which seemed at odds with the will of the people, who Parliament believed they were destined to represent. Charles was assertive that he could put in place whatever mechanisms he chose, as was the function of his Divine Right as a King. Parliament had made the relationship with the King equally untennable, leading to war. During Charles' first years as King, they made it very difficult for him to raise funds for what he believed to be necessary actions of the Kingdom, namely war. This came to a head in 1638, where Charles required funds for a war against Scotland which Parliament refused to provide. Overall, the English Civil War was caused by a finacial burden in the short-term, but is better viewed as an ideological battle between King and country that developed over the course of a decade.
