The document provides details about the growth of Indian nationalism and independence movements between 1920-1930. It summarizes the Non-Cooperation Movement launched by Mahatma Gandhi against the Rowlatt Act in 1919. The movement involved boycotting British goods and civil services. It spread widely but had to be withdrawn in 1922 after violent incidents. This led to the launch of the Civil Disobedience Movement in 1930 against the salt tax. The Dandi March and subsequent acts of disobedience and protests spread across India and led to many arrests including of Gandhi. While the movements united many Indians, they also faced limitations in fully representing Dalits and Muslims.
