What was it gunpowder plot?

The Gunpowder Plot was a failed conspiracy in 1605 aimed at assassinating King James I of England and blowing up the House of Lords to disrupt the Protestant government. Led by a group of Catholic conspirators, including Guy Fawkes, the plot sought to restore Catholic rule. The conspirators were discovered before they could execute their plan, leading to their arrest and execution. The event is commemorated annually in the UK on November 5th, known as Guy Fawkes Night.
