On 5 November 1688, William of Orange landed at Brixham and began the last successful invasion of England. His goal was London. The prize was the English crown. But why did William really invade?The traditionalview is that he only came because he was invited, and that he was the duller partner in the dual monarchy of William and Mary. But William was nobody's dupe. He saw England as a weapon to be used in his European campaigns.Peter France tells the story from William's perspective, and points out the price that was paid by the English for constitutional monarchy and the rule of Parliament.
