In our secondary-school history lessons, we were taught that the 1857 rebellion by sepoys serving in the East India Company’s army was caused by their unease about handling Enfield rifles and cartridges greased with beef and pork fat. The sepoys needed to bite open the cartridges before loading their rifles. This was unacceptable to Hindu and Muslim soldiers alike. They revolted, but the British managed to suppress the resistance and continued to rule India for another 90 years.
