and members of a group close to the Prince and Princess of Denmark, known as the 'Cockpit circle', had deserted the king and transferred their allegiance to Prince William. This group included, Lord Cornbury, master of the horse to Prince George and the first major defector from the royal side, Henry Fitzroy, 1 st duke of Grafton, James Butler, 2 nd duke of Ormonde, Lord John Churchill and Colonel John Berkeley, master of the horse to Princess Anne of Denmark. 1 A few days later Anne retreated from the court in London and made her way towards the Midlands. The desertion of the highest ranking Protestant members of the royal family, then resident in England, inflicted serious political injuries on James II, and foreshadowed the collapse of his regime. This statement may seem improbable, but a royal defection on such a scale had tremendous symbolic power. In the opening stages of the Glorious Revolution, through their involvement in ceremonies in urban communities, George and Anne used this power to demonstrate their support for the Williamite cause. These performances are largely neglected-especially the ones enacted by George-but our understanding of the Glorious Revolution is incomplete without incorporating the evidence of ephemeral events that at the time, were considered important. It is clear that Princess Anne of Denmark played a significant role in the Revolution, and she will be mentioned at various points in what follows, but this article will concentrate on the part played by Prince George. To understand fully the political significance of Prince George's participation in the Glorious * I would like to thank Toby Barnard, Gabriel Glickman, David Hayton, Grant Tapsell, Martin Conway and the two anonymous reviewers of this journal for their insightful comments and suggestions on earlier drafts of this article.
