The famous leader associated with the establishment of an independent India is Mahatma Gandhi. He played a crucial role in India's struggle for independence from British colonial rule through nonviolent civil disobedience and mass mobilization. Gandhi’s philosophy of satyagraha, or truth-force, inspired countless people to join the movement, advocating for equality and justice. His leadership during significant campaigns, such as the Salt March in 1930, showcased the power of collective action. The culmination of his efforts, alongside the contributions of many other leaders, led to India gaining independence on August 15, 1947, marking a significant moment in the fight against imperialism.
