It was 1605. Guy Fawkes was trying to blow up the House of Lords (Robert Catsbey planned that idea). But King James the first thought something was going on with Guy Fawkes and his little gang (he was sent a letter).
Because of that letter, he thought that he would send him men out and search for the gun powder plots, and the gun powder (36 barrels of gun powder).
Guy Fawkes was planning with Robert Catesby about blowing up everybody in the country, but then the king sent his men out to find Guy Fawkes and Robert Catesby, "MEN! I am sending you to go and find Guy Fawkes and Robert Catesby." The King yelled to his men.
So they went searching and found them and showed both guilty men to the King.
They tied Guy Fawkes up and burned him and Robert was killed.
