There were two Tory ministries after James II came to the throne: the first led by the Earl of Rochester, the second by Lord Belasyse. A significant faction took part in the ousting of James II with the Whigs to defend the Church of England and definitive protestantism. A large but dwindling faction of Tories continued to support James in exile and his Stuart heirs to the throne, especially in 1714 after the accession of George I, the first Hanoverian monarch. Although only a minority of Tories gave their adhesion to the Jacobite risings, this was used by the Whigs to discredit the Tories and paint them as traitors. After the advent of the Prime Ministerial system under the Whig Robert Walpole, Lord Bute's premiership in the reign of George III marked a revival. Under the Corn Laws (1815–1846) a majority of Tories supported protectionist agrarianism with tariffs being imposed at the time for higher food prices, self-sufficiency and enhanced wages in rural employment.
