There was Norman influence from the 14th century, including by the FitzGerald, de Clare and Butler houses, two of whom carved out earldoms within the Lordship of Ireland, the Earls of Desmond eventually becoming independent potentates, while the Earls of Ormond remained closer to England. The O'Brien of Thomond and MacCarthy of Desmond surrendered and regranted sovereignty to the Tudors in 1543 and 1565, joining the Kingdom of Ireland. The impactful Desmond Rebellions, led by the FitzGeralds, soon followed.
