Why did the gunpowder plot happened?

The Gunpowder Plot of 1605 was a failed conspiracy by a group of English Catholics, including Guy Fawkes, to assassinate King James I and blow up the Houses of Parliament. The plotters aimed to end Protestant rule and replace it with a Catholic monarch, hoping to alleviate the oppressive laws against Catholics in England. Their plan was foiled when authorities received an anonymous tip, leading to the arrest of Fawkes and his co-conspirators. The event is commemorated annually in the UK on Guy Fawkes Night.
