King James was a protestant King but Catholics were unhappy with James. Catholic people thought different, they fought that God liked very beautiful churches with lots of decorations.
The plotters made a plan with the third friend they met in the town. He was called Robert Catesby he talked with them and agreed that he help them with the plan. Unfortunately before they could do anything think they somebody who actually knew how to use the gunpowder.
The soldiers arrested Guy Fawkes then put him in prison. He snitched on them and told them were they are and who they are. They got arrested too, and tried for treason. Treason means trying to harm a King or Queen.
Guy Fawkes thought he needed to get gunpowder under the Houses of Parliament... and he found someone who he has a basement that leads down to the House of Parliament.
Someone how was in with the plan snitched on them. He said people are trying to blow you up. He said that because he wasn't happy with the plan and because he didn't want his friend to die. The soldiers searched the Parliament they didn't find anyone but they did find a person in the basement waiting for King Richard to sit on his chair.
Guy Fawkes and his crew was arrested. They had to say there they name or they be dead they said their names but then they got tortured them and King James was still King.
