The Rebellion of 1857, also known as the Indian Mutiny or Sepoy Rebellion, was a widespread but ultimately unsuccessful uprising against British rule in India. It arose from a combination of grievances among Indian soldiers (sepoys) in the British East India Company's army, including cultural insensitivity and exploitation, leading to a broader revolt involving various segments of Indian society. The rebellion marked a significant turning point in Indian history, highlighting the growing resentment towards colonial rule and prompting changes in British imperial policies.
