In a small london pub, six Catholic men gathered and began to plot how they would get rid of King James and other protestants. They decided that they would do this by exploding gunpowder underneath westminster.
You may be thinking how on earth the plotters would do this. Guido Fawkes ( aka Guy Fawkes) and his crew rented a room next to Westminser and a room underneth the hall. This way they could store the barrells of gunpowder until the day came.
This is where it all started to go wrong. Francais Thresham sent a letter to his uncle, warning him not to go to paliment that day. However, Threshams Uncle was concerned and told everyone about the letter. This meant that the plot was one step closer togoing wrong.
