In 1605, a group of English Catholics led by Robert Catesby planned to kill King James I by blowing up the House of Lords with gunpowder on November 5th. Guy Fawkes was tasked with preparing and guarding 36 barrels of gunpowder placed beneath the House. However, the authorities were warned anonymously and arrested Fawkes before he could light the fuse. The plotters were subsequently hunted down, tried for treason, and executed. Today the failed Gunpowder Plot is commemorated annually in Britain as Guy Fawkes Night with fireworks displays and bonfires.
