The major effect of the Great Rebellion in India in 1857, also known as the Sepoy Mutiny, was the end of the British East India Company's rule over India and the establishment of direct British control, known as the British Raj. The rebellion stemmed from widespread discontent among Indian soldiers (sepoys) and was fueled by cultural, political, and economic grievances. Although the uprising was ultimately suppressed, it marked a significant turning point, leading to major reforms in British administration and military policies. This event sowed the seeds for future nationalist movements, fostering a sense of Indian identity and unity against colonial rule.
