The Gunpowder Plot of 1605, in earlier centuries often called the Gunpowder Treason Plot or the Jesuit Treason, was an unsuccessful attempted regicide against King James I by a group of English Catholics led by Robert Catesby who considered their actions attempted tyrannicide and who sought regime change in England after decades of religious persecution.

James VI and I was King of Scotland as James VI from 24 July 1567 and King of England and Ireland as James I from the union of the Scottish and English crowns on 24 March 1603 until his death in 1625. Although he long tried to get both countries to adopt a closer political union, the kingdoms of Scotland and England remained sovereign states, with their own parliaments, judiciaries, and laws, ruled by James in personal union. He was the longest-reigning monarch of the Kingdom of Scotland.
