What challenges did Charles I face as ruler?

Charles I faced significant challenges during his reign, primarily stemming from his belief in the divine right of kings, which led to conflicts with Parliament. His attempts to impose royal authority and raise taxes without parliamentary consent sparked widespread discontent, culminating in the English Civil War. Additionally, religious tensions, particularly regarding the Church of England and Puritan dissenters, further exacerbated divisions within his kingdom. Ultimately, these challenges contributed to his execution in 1649.
