A Foxite was an 18th or 19th century British Whig politician who adhered to the ideals and political beliefs of Charles James Fox, the 18th century member of parliament and leader of the Whig party. Charles James Fox was the generally acknowledged leader of a faction of the Whigs, from 1794 until his death in 1806. This group had developed from successive earlier factions; known as the "Old Corps Whigs" (led by the Duke of Newcastle in the 1750s and early 1760s), the "Rockingham Whigs" (who had supported the Marquess of Rockingham from the mid-1760s until his death in 1782) and the "Portland Whigs" who had followed the Duke of Portland who had succeeeded Rockingham as Prime Minister.
