 In 1502, James IV of Scotland signed the Treaty of Perpetual Peace with Henry VII of England. He also married Henry's daughter, Margaret Tudor, setting the stage for the Union of the Crowns. For Henry, the marriage into one of Europe's most established monarchies gave legitimacy to the new Tudor royal line. A decade later, James made the fateful decision to invade England in support of France under the terms of the Auld Alliance. He was the last British monarch to die in battle, at the Battle of Flodden. Within a generation the Auld Alliance was ended by the Treaty of Edinburgh. France agreed to withdraw all land and naval forces. In the same year, 1560, John Knox realised his goal of seeing Scotland become a Protestant nation and the Scottish parliament revoke papal authority in Scotland. Mary, Queen of Scots, a Catholic and former queen of France, was forced to abdicate in 1567.
