The Nationalist Movement in India was a campaign aimed at ending British colonial rule. It began in the late 19th century and gained momentum in the early 20th century, with leaders like Mahatma Gandhi and Jawaharlal Nehru advocating for independence through non-violent protests and civil disobedience. The movement united various groups across the country, emphasizing the importance of self-rule and national identity. Key events included the Indian National Congress formation in 1885 and the Quit India Movement in 1942, which called for an immediate end to British rule. The movement ultimately led to India's independence on August 15, 1947, marking a significant moment in the country's history.
