The Enfield P53 was introduced to Indian troops under British rule in 1856. The Enfield rifle-musket was a contributing cause of the Indian rebellion of 1857. Sepoys in the British East India Company's armies in India were issued with the new rifle in 1857, and rumours were spread that the cartridges (referring here to paper-wrapped powder and projectile, not to metallic cartridges) were greased with beef tallow, pig fat, or a combination of the two – a situation abhorrent to Hindu and Muslim soldiers based on religious beliefs.
