Jacobitism was revived by the unpopularity of the union with England in 1707. In 1708 James Francis Edward Stuart, the son of James VII, who became known as "The Old Pretender", attempted an invasion with French support. The two most serious risings were in 1715 and 1745. The first was soon after the death of Anne and the accession of the first Hanoverian king George I. It envisaged simultaneous uprisings in England, Wales and Scotland, but they only developed in Scotland and Northern England. John Erskine, Earl of Mar, raised the Jacobite clans in the Highlands. Mar was defeated at Battle of Sheriffmuir and day later part of his forces, who had joined up with risings in northern England and southern Scotland, were defeated at the Battle of Preston. By the time the Old Pretender arrived in Scotland the rising was all but defeated and he returned to continental exile. The 1745 rising was led by Charles Edward Stuart, son of the "Old Pretender", often referred to as "Bonnie Prince Charlie" or the "Young Pretender". His support was almost exclusively among the Highland clans. The rising enjoyed initial success, with Highland armies defeating Hanoverian forces and occupying Edinburgh before an abortive march that reached Derby in England. Charles' position in Scotland began to deteriorate as the Scottish Whig supporters rallied and regained control of Edinburgh. He retreated north to be defeated at Culloden on 16 April 1746. There were bloody reprisals against his supporters and foreign powers abandoned the Jacobite cause, with the court in exile forced to leave France. The Old Pretender died in 1760 and the Young Pretender, without legitimate issue, in 1788. When his brother, Henry, Cardinal of York, died in 1807, the Jacobite cause was at an end. The Jacobite risings highlighted the social and cultural schism within Scotland, between the "improved," English and Scots-speaking Lowlands and the underdeveloped Gaelic-speaking Highlands.
