parliamentary support. Pelham returned to office triumphant, and George was forced to appoint Pitt to the ministry. George's French opponents encouraged rebellion by the Jacobites, the supporters of the Roman Catholic claimant to the British throne, James Francis Edward Stuart, often known as the Old Pretender. Stuart was the son of James II, who had been deposed in 1688 and replaced by his Protestant relations. Two prior rebellions in 1715 and 1719 had failed. In July 1745, the Old Pretender's son, Charles Edward Stuart, popularly known as Bonnie Prince Charlie or the Young Pretender, landed in Scotland, where support for his cause was highest. George, who was summering in Hanover, returned to London at the end of August. The Jacobites defeated British forces in September at the Battle of Prestonpans, and then moved south into England. The Jacobites failed to gain further support, and the French reneged on a promise of help. Losing morale, the Jacobites retreated back into Scotland.

The ravaged Jacobite troops were routed by the government army. Charles escaped to France, but many of his supporters were caught and executed. Jacobitism was all but crushed; no further serious attempt was made at restoring the House of Stuart.

Planning for succession In the general election of 1747 Frederick, Prince of Wales again campaigned actively for the opposition but Pelham's party won easily. Like his father before him, the Prince entertained opposition figures at his house in Leicester Square. When Prince Frederick died unexpectedly in 1751, his eldest son, Prince George, became heir apparent. The King commiserated with the Dowager Princess of Wales and wept with her. As her son would not reach the age of majority until 1756, a new British Regency Act was passed to make her regent, assisted by a council led by Frederick's brother, Prince William, Duke of Cumberland, in case of George II's death. The King also made a new will, which provided for Cumberland to be sole regent in Hanover. After the death of his daughter Louisa at
