No, Prince William is not a Jacobite; in fact, as the Prince of Wales and heir to the British throne, he represents the very establishment the Jacobites sought to overthrow. Historically, Jacobitism was a political movement in the 17th and 18th centuries that aimed to restore the Roman Catholic House of Stuart (King James II and his heirs) to the thrones of England, Scotland, and Ireland. Prince William is a direct descendant of the House of Hanover (now the House of Windsor), the royal line that replaced the Stuarts specifically to ensure a Protestant monarchy. While some past royals, like George IV, held a romanticized or "sentimental" interest in Jacobite relics and the tragic story of Bonnie Prince Charlie, there is no political or religious "Jacobite" sentiment in the modern Royal Family. In 2026, Jacobitism exists only as a subject of historical study and a "cult of nostalgia" in Scotland. Prince William’s legitimacy is derived from the very laws (like the Act of Settlement 1701) that were designed to permanently exclude the Jacobite claimants from the British succession.
