Who smuggled gunpowder into parliament?

Guy Fawkes is famously known for attempting to smuggle gunpowder into the British Parliament in 1605 as part of the Gunpowder Plot. The plan aimed to assassinate King James I and blow up the House of Lords to end Protestant rule in England. Fawkes was caught in the act, leading to his execution and the commemoration of November 5th as Guy Fawkes Night.
