English Civil War
In the previous century, the Protestant Reformation and England's break with the Catholic Church had encouraged new ideas and struggles. In England, there was movement called the Puritans, because they wanted a "pure" religion. They believed that the Church of England was too much like the Roman Catholic Church it had broken away from. In particular, they did not want the church to have bishops. There was a similar movement in Scotland. The Church of Scotland also had bishops, but it had many differences with the Church of England.
