Sepoys were Indian soldiers who served in the armies of the British East India Company during the 18th and 19th centuries. They were primarily recruited from various regions of India and played a crucial role in maintaining British control over the subcontinent. The term "sepoy" is derived from the Persian word for soldier. The most notable event involving sepoys was the Sepoy Mutiny of 1857, also known as the Indian Rebellion of 1857. This uprising was sparked by various grievances, including cultural insensitivity and the introduction of new rifle cartridges. The rebellion marked a significant turning point in Indian history, leading to direct British rule in India.
