The Revolt of 1857 was caused by widespread dissatisfaction with British policies, including heavy taxation, land revenue systems, and interference in social and religious practices. Immediate triggers included grievances among Indian soldiers regarding service conditions. The revolt spread across northern and central India and involved rulers, soldiers, peasants, and civilians. Although it was ultimately suppressed, the revolt marked a turning point in Indian history. It ended Company rule and led to direct British Crown administration, while also strengthening Indian resistance and political awareness against colonial domination.
