Before the regiment was reformed as part of a reorganization of the British Army in 1881, the Royal Munster Fusilier's historic background went back as far as 1652 with the formation of the Bengal European Regiment by the Honourable East India Company.
This regiment would eventually become the 101st Regiment of Foot (Royal Bengal Fusiliers), or the 1st Bengal European Fusiliers.
The East India Company formed the 104th Regiment of Foot (Bengal Fusiliers), or 2nd Bengal European Fusiliers, from this regiment in 1765.
Both regiments, which were composed exclusively of white soldiers, not Indian sepoys, played pivotal roles in the British conquest of India throughout the 18th and 19th centuries.

As well as the Royal Munster Fusilier's origins as part of the East India Company, the regiment's reserve battalions also traced their lineage to the Militia of Munster (namely the South Cork Light Infantry Militia, the Kerry Militia and the Royal Limerick County Militia, which became the 3rd, 4th and 5th Battalions, respectively).
While both the fusilier regiments had originated and served as "European" regiments of the East India Company, they were transferred to the British Army in 1861 when the British Crown took control of the company's private army after the Indian Mutiny of 1857.
