Gandhi's nonviolence was the product of India in the first half of the 20th century. It is a social and political philosophy, and Gandhi tried to use it to solve various contradictions and disputes in social politics, and to solve disputes and conflicts between people, groups and groups, and nations. This non-violent philosophy not only inherits the traditional Indian religious and ethical theories, but also absorbs many modern western political philosophies and humanitarian thoughts, which can be said to be the fusion of eastern and western thoughts. 1906, Gandhi first put forward this theory in the struggle against racial discrimination led by Indian expatriates in South Africa. Later, he returned to India and continued to practice and improve in the movement of national independence and social reform, making it gradually become a relatively complete political theory. This theory has a far-reaching impact not only on the Indian people, but also on the Asian and African people fighting for national independence, the African-American movement against racial discrimination and the modern international political struggle. Results: 1922 broke through the non-violent boundary, and Gandhi and the Congress Party stopped the movement, which made the national anti-imperialist movement in India fall into a trough.
