When Queen Elizabeth 1st took the throne of England she made some laws against the Roman Catholics. Guy Fawkes was one of a small group of Catholics who felt that the government was treating Roman Catholics unfairly. They hoped that King James 1st would change the laws, but he didn't.

Catholics had to practise their religion in secret. There were even fines for people who didn't attend the Protestant church on Sunday or on holy days. James lst passed more laws against the Catholics when he became king.
