The title Earl of Desmond was first created for Maurice FitzGerald, 4th Baron Desmond in approximately 1329. Over time, according to English sources, the FitzGerald family became highly assimilated to the local Irish culture. The final Earl of Desmond of this creation was Gerald FitzGerald, the 15th (or, by some counts, the 16th) Earl. The FitzGeralds and Fitzmaurices had resisted the Protestant Reformation of King Henry VIII and, after the failure of the first and second Desmond Rebellions, the 15th Earl was defeated and killed by forces loyal to Queen Elizabeth I on 11 November 1583. His title, along with the enormous estates of his family, were forfeit to the English Crown. His nephew, James FitzThomas FitzGerald, attempted to regain control of both during the Nine Years War, but he was captured by the English and executed in 1603.
