In which year did Mahatma Gandhi first introduce a nationwide satyagraha in India?

1919

The correct answer is Option 3- 1919

Mahatma Gandhi first introduced a nationwide satyagraha in India in 1919. This was the Rowlatt Satyagraha, which was a protest against the Rowlatt Act, a repressive law passed by the British government in India. The act gave the government the power to arrest and detain people without trial.

Gandhi called for a nationwide hartal (strike) on March 30, 1919, to protest the Rowlatt Act. The hartal was largely successful, and it showed the British that the Indian people were united in their opposition to the law.

The Rowlatt Satyagraha was a turning point in the Indian independence movement. It was the first time that Gandhi had launched a nationwide satyagraha, and it showed the power of non-violent resistance. The satyagraha also helped to raise Gandhi's profile as the leader of the Indian independence movement.
