Meanwhile, Queen Mary had been raised as a Catholic in France, and married to the Dauphin, who became king as Francis II in 1559, making her queen consort of France. When Francis died in 1560, Mary, now 19, returned to Scotland to take up the government. Despite her private religion, she did not attempt to re-impose Catholicism on her largely Protestant subjects, thus angering the chief Catholic nobles. Her six-year personal reign was marred by a series of crises, largely caused by the intrigues and rivalries of the leading nobles. The murder of her secretary, David Riccio, was followed by that of her unpopular second husband Lord Darnley, and her abduction by and marriage to the Earl of Bothwell, who was implicated in Darnley's murder. Mary and Bothwell confronted the lords at Carberry Hill and after their forces melted away, he fled and she was captured by Bothwell's rivals. Mary was imprisoned in Loch Leven Castle, and in July 1567, was forced to abdicate in favour of her infant son James VI. Mary eventually escaped and attempted to regain the throne by force. After her defeat at the Battle of Langside in 1568, she took refuge in England, leaving her young son in the hands of regents. In Scotland the regents fought a civil war on behalf of James VI against his mother's supporters. In England, Mary became a focal point for Catholic conspirators and was eventually tried for treason and executed on the orders of her kinswoman Elizabeth I.
