The Gunpowder Plot: This conspiracy arose from the English Catholics' resentment of King James I and his reign's treatment of their religion. A group of extremists led by Rober Catesby planed to seize power by killing King James I and his ministers at the State Opening of Parliament (November 5, 1605), leaving England without a government. Francis Tresham, one of the conspirators, gave the plan away when he wrote to his brother-in-law, Lord Monteagle, telling him to stay away from the Houses of Parliament during the Opening. Monteagle informed the Lord Chancellor of the warning, who in turn told the king. On November 4, 1605, Guy Fawkes was arrested in the cellars of the House of Lords, standing guard over two tons of gunpowder. He was tortured until he revealed the names of his co-conspirators, who, if they hadn't yet fled the country, were soon executed. Now the British celebrate November 5 with bonfires, fireworks, and by burning effigies of Guy. Theoretically, they are celebrating the execution of a traitor, though some have been been known to see it as a celebration of the near death of the monarchy.
