The Desmond Rebellions, which occur in 1569-1573 and 1579-1583 in the Irish province of Munster, are ebellions by the Earl of Desmond -- head of the FitzGerald dynasty in Munster -- and his followers, the Geraldines and their allies against the threat of the extension of Elizabethan English government over the province.

The rebellions are motivated primarily by the desire to maintain the independence of feudal lords from their monarch, but also have an element of religious antagonism between Catholic Geraldines and the Protestant English state.

The result is the destruction of the Desmond dynasty and the subsequent plantation or colonization of Munster with English settlers.

'Desmond' is the Anglicisation given to the Irish Deasmumhain, which translates to 'South Munster'.
