The Despenser War (1321–22) was a baronial revolt against Edward II of England led by the Marcher Lords Roger Mortimer and Humphrey de Bohun. The rebellion was fuelled by opposition to Hugh Despenser the Younger, the royal favourite. After the rebels' summer campaign of 1321, Edward was able to take advantage of a temporary peace to rally more support and a successful winter campaign in southern Wales, culminating in royal victory at the battle of Boroughbridge in the north of England in March 1322. Edward's response to victory was his increasingly harsh rule until his fall from power in 1326.
