The "Count of Desmond" refers to a title associated with the earldom of Desmond, located in Ireland. This title was historically held by the MacCarthy and Fitzgerald families, who played significant roles in Irish history, particularly during the late medieval period. The earldom was known for its influence and power in the region. The title became extinct in the late 17th century after the Williamite War in Ireland, which led to the defeat of the Irish Catholic nobility. The last holder of the title was James FitzGerald, the 14th Earl of Desmond, who was executed in 1601.
