What was the main reason for the English civil war of 1642

Religion was a major cause of the English Civil War. It was part of a Europe wide conflict between Roman Catholicism and Protestantism. At the start of his reign (1625) King Charles I had married the Roman Catholic Henrietta Maria of France.

Discontent with the rule of King Charles, the belief that the poverty much of England endured was due to mismanagement by King Charles, King Charles married a Catholic which angered ever increasingly Puritan sentiment, King Charles refusal to meet with Parliament, attempts to suppress Parliament and King Charles mishandling of the Scottish revolt.
