The English Civil War was a defining conflict that shaped British democracy. It was fought between those who supported Parliament and those who supported King Charles I.
Causes
The war had several causes:
- Religious tensions - Disputes over the Church of England
- Money - Charles I tried to raise taxes without Parliament's consent
- Power struggle - Who should rule: King or Parliament?
- Scotland - Charles's attempt to impose Anglican worship on Scotland
Charles I believed in the "divine right of kings" - that his power came from God and Parliament had no right to limit it.
