The Desmond rebellion was one of the most brutal military conflicts to have taken place in Ireland in the sixteenth century. Initiated by James FitzMaurice Fitzgerald, cousin of Gerald, fifteenth earl of Desmond, in July 1579 in order to restore the Catholic faith in Ireland, the rebellion quickly developed from the landing of a small expeditionary force of approximately sixty men into a bloody contest which engulfed Munster for four and a half years. The rebellion was ultimately unsuccessful, but such was the ferocity of the conflict that it had a profound and devastating impact on Munster. The social and economic consequences were immense, for it exacted a huge economic cost on the province, both in terms of physical destruction and lost economic activity, and produced a very substantial depopulation of the province. The result was the overthrow and destruction of the traditional social order in Munster, an act that paved the way for the subsequent Munster plantation.

At the beginning of the sixteenth century the Fitzgerald earls of Desmond were among the élite of Hiberno-Norman society in Ireland. Equalled in status among the nobility of Ireland only by the earls of Kildare and of Ormond, the Desmonds possessed great power, wealth and influence. Their huge earldom, which covered much of Munster, rendered them the virtual masters of the province and of all the Gaelic Irish and Hiberno-Norman lords therein.

Yet by 1584 they were gone, the earl of Desmond killed while in rebellion, the earldom broken up as an entity, the estates and castles in ruins. Apart from a short-lived return at the end of the century, the house of Desmond was defunct.

The dramatic fall of the house of Desmond has intrigued many historians, who seek its cause in the period leading up to the 1580s and in the political context of the time. They cite the breakdown of the earl’s control, the indebtedness of the earldom, the alleged madness and incapacity for rule of Gerald, the fifteenth earl. They refer to the extension of crown control in Elizabethan Ireland, the English fear of foreign intervention in Ireland, and the campaign for conformity to the new Protestant religion.
