India's struggle for independence from British rule began in the late 19th century and intensified in the early 20th century. Key events included the Indian National Congress formation in 1885 and the Non-Cooperation Movement led by Mahatma Gandhi in 1920. The demand for self-rule grew stronger as Indians faced economic hardships and social injustices under colonial rule. The struggle saw various movements, including the Civil Disobedience Movement and the Quit India Movement in 1942. After years of protests, negotiations, and sacrifices, India finally gained independence on August 15, 1947, marking the end of nearly 200 years of British colonial rule.
