The major rebellion that arose from resistance to British rule in India in 1857 is known as the Sepoy Rebellion, or the Indian Mutiny. It began as a revolt by Indian soldiers (sepoys) in the British East India Company's army against practices perceived as disrespectful to their religion, such as the use of animal fat in rifle cartridges. The rebellion quickly escalated, encompassing a wide range of social and political discontent against British rule. While the uprising was ultimately suppressed, it marked a significant turning point, leading to increased scrutiny of British policies and eventually the transition of power from the East India Company to the British Crown in 1858.
