The Dandi March, also known as the Salt March, was a significant event in India's struggle for independence from British rule. It was led by Mahatma Gandhi on March 12, 1930, as part of the Civil Disobedience Movement. During this march, Gandhi and his followers walked from Sabarmati Ashram in Ahmedabad to the coastal village of Dandi, where they symbolically violated the British salt laws by making salt from seawater. This act of civil disobedience became a powerful symbol of resistance against British colonial rule.
Here's why the other options are incorrect:
- Option (1): 1922: In 1922, Gandhi called off the Non-Cooperation Movement after violent incidents at Chauri Chaura, where protesters attacked a police station. The Dandi March occurred later.
- Option (2): 1927: This year is not directly associated with the Dandi March. Important events such as the Simon Commission visit took place in 1927, but the Dandi March happened in 1930.
- Option (3): 1930: This is the correct answer, as the Dandi March began on March 12, 1930, marking a pivotal moment in India's freedom struggle.
- Option (4): 1932: In 1932, Gandhi undertook the Round Table Conferences in London to negotiate India's future with the British government. The Dandi March predates this event.
