When did King James join the gunpowder plot?

King James I was not a participant in the Gunpowder Plot; in fact, he was the target of the conspiracy. The plot was devised by a group of Catholic conspirators, including Guy Fawkes, in 1605 to assassinate the king and blow up the House of Lords during the State Opening of Parliament. The conspirators aimed to end Protestant rule in England and restore Catholic leadership. The plot was foiled on November 5, 1605, leading to the execution of the conspirators.
