However, his tenure as Lord Lieutenant lasted only a year and a half. The post was abolished with the coming into existence of the Irish Free State and its constitution in 1922. The position was replaced by the offices of the Governor-General of the Irish Free State and the Governor of Northern Ireland. The day after his appointment as Lord Lieutenant he was raised to the Peerage as Viscount FitzAlan of Derwent, of Derwent in the County of Derby. In addition, during the minority of his nephew the 16th Duke of Norfolk, who succeeded to the dukedom in 1917, he served as Deputy Earl Marshal.
