George I became the first Hanoverian king of Great Britain in 1714 after Queen Anne's death. As he did not speak English, he relied heavily on his Whig Party supporters who came to dominate the government. During the early Hanoverian period, there was significant corruption under Prime Minister Walpole, while the Church of England declined. Meanwhile, Jacobites who supported the deposed Catholic King James Stuart staged two rebellions in Scotland to restore him to the throne, but both failed due to lack of support and competent leadership. The Whig government was able to put down the risings.
