The regiment was created on 1 July 1881 as a result of Childers Reforms by the amalgamation of the 102nd Regiment of Foot (Royal Madras Fusiliers) and the 103rd Regiment of Foot (Royal Bombay Fusiliers). Both the fusilier regiments had originated as "European" regiments of the East India Company and transferred to the British Army in 1861 when the British Crown took control of the company's private army after the Indian Rebellion of 1857. Under the reforms five infantry battalions were given Irish territorial titles and the 102nd and 103rd Regiments of Foot became the 1st and 2nd Battalions, The Royal Dublin Fusiliers.
