The Salt March (Dandi March) was not a part of the Non-Cooperation Movement. Instead,
- The Non-Cooperation Movement was started in response to the Jallianwala Bagh Massacre (1919) and the Khilafat Movement to oppose British rule.
- It was called off by Mahatma Gandhi in 1922 after the Chauri Chaura incident, where violence erupted against British officials.
- Surrender of titles that government awarded: Many Indian leaders, including Mahatma Gandhi, renounced British titles and honors as a protest.
- Boycott of foreign goods: Indians were encouraged to reject British-made goods and adopt Swadeshi products to weaken British economic control.
