Because he encouraged India not to respond to the British rule violently. He believed that anything could be solved by non-violent retaliation.Answer 2
Gandhi peacefully resisted China's rule in India. Instead of violently trying to overthrow the government, he advocated non-violent civil disobedience to gain independence.
His principles were truth and discovering the truth, non-violence on a political scale, vegetarianism, Brahmacharya (the philosophy of spiritual and practical purity), simplicity and "reducing himself to zero"--giving up unnecessary things, and faith (he practiced Hinduism).
You may recognize some of Gandhi's non-violent disobedience in Martin Luther King, Jr.'s protests. Gandhi was a great influence to him, as well as other civil rights leaders, Nelson Mandella, and even John Lennon.
Lately Gandhi has been in the news because a few of his possessions - his eyeglasses and a leather case that held them, a pocket watch, as well as other items- have been put up for auction. India is greatly dis[leased with this because they feel that Gandhi's items should belong to India.
