The Contrariants were an aristocratic faction in England in the early 14th century.
They were most prominent in the Welsh Marches and northern England.
[1] During the civil war of 1321–1322, they fought against the Despensers and King Edward II.
Among those executed for treason were Thomas, 2nd Earl of Lancaster; Humphrey de Bohun, 4th Earl of Hereford; and Bartholomew Badlesmere.
[1] One of the Contrariant leaders who escaped to France, Roger Mortimer, led an invasion of England in 1326, overthrowing Edward and executing the Despensers.
