The Whig Split occurred between 1717 and 1720, when the governing British Whig Party divided into two factions: one in government, led by James Stanhope; the other in opposition, dominated by Robert Walpole. It coincided with a dispute between George I and his son George, Prince of Wales, with the latter siding with the opposition Whigs. It is also known as the Whig Schism.[1] After three years it was resolved by a reconciliation between the two factions. Walpole went on to serve as Prime Minister from 1721 to 1742.
