The 1780 British general election returned members to serve in the House of Commons of the 15th Parliament of Great Britain to be summoned after the merger of the Parliament of England and the Parliament of Scotland in 1707. The election was held during the American War of Independence and returned Lord North to form a new government with a small and rocky majority. The opposition consisted largely of the Rockingham Whigs, the Whig faction led by the Marquess of Rockingham. North's opponents referred to his supporters as Tories, but no Tory party existed at the time and his supporters rejected the label.
