Plot thumb|right|upright=1.1|alt=Painting|King James's daughter Elizabeth, whom the conspirators planned to install on the throne as a Catholic queen. Portrait by Robert Peake the Elder, National Maritime Museum. The conspirators' principal aim was to kill King James, but many other important targets would also be present at the State Opening of Parliament, including the monarch's nearest relatives and members of the Privy Council. The senior judges of the English legal system, most of the Protestant aristocracy, and the bishops of the Church of England would all have attended in their capacity as members of the House of Lords, along with the members of the House of Commons. Another important objective was the kidnapping of the King's daughter, Elizabeth. Housed at Coombe Abbey near Coventry, she lived only ten miles north of Warwick—convenient for the plotters, most of whom lived in the Midlands. Once the King and his Parliament were dead, the plotters intended to install Elizabeth on the English throne as a titular Queen. The fate of her brothers, Henry and Charles, would be improvised; their role in state ceremonies was, as yet, uncertain. The plotters planned to use Henry Percy, 9th Earl of Northumberland, as Elizabeth's regent, but most likely never informed him of this.
