When did Mahatma Gandhi initiate the 'Salt Satyagraha'?

Mahatma Gandhi initiated the 'Salt Satyagraha' (also known as the Salt March or Dandi March) in 1930, which became one of the most iconic acts of civil disobedience in India's freedom struggle. Beginning on March 12, Gandhi led a 24-day march from Sabarmati Ashram to Dandi to produce salt illegally, directly challenging the British salt monopoly. This carefully chosen symbolic protest against an essential commodity's taxation galvanized mass participation in the independence movement. The Salt Satyagraha demonstrated the effectiveness of non-violent resistance and significantly undermined British colonial authority.
