The 1857 Uprising, also known as the Sepoy Mutiny, was a significant rebellion against British rule in India. It began when Indian soldiers, or sepoys, in the British East India Company's army revolted due to various grievances, including cultural insensitivity and the introduction of new rifle cartridges rumored to be greased with animal fat. The uprising spread quickly, with widespread participation from various Indian communities. The rebellion was marked by fierce fighting and significant events, such as the siege of Delhi and the capture of Kanpur. Although the uprising was ultimately suppressed by British forces, it marked a turning point in Indian history, leading to the end of the East India Company's rule and the establishment of direct British governance in India.
