Civil disobedience is the active refusal to obey certain laws, demands and commands of a government, or of an occupying power, without resorting to physical violence. It is one of the primary tactics of nonviolent resistance.
Mohandas Karamchand Gandhi (also known as Mahatma Gandhi) used non-violent civil disobedience in South Africa in a campaign for civil rights for the people who came from India and lived in South Africa. This campaign was from 1893-1914. When Gandhi returned to India, he used civil disobedience in the campaign for the independence of India in 1930 from the British rule, when India was a British colony.
