Mohandas Karamchand Gandhi (October 2, 1869 – January 30, 1948), also known as Mahatma Gandhi, was an Indian lawyer, anti-colonial nationalist, and political ethicist who employed nonviolent civil disobedience to lead India to independence from British rule and in turn inspire movements for civil rights and freedom across the world.
Gandhi developed his concept of satyagraha, which advocated for ethical vegetarianism, kindness to people of all backgrounds, and especially kindness to people of one's own ethnicity to fight against inequality of the caste system prevalent at that time during British Raj in early 20th century India.
While Mahatma Gandhi did much to inspire the world regarding how to live as good people, there is no evidence to indicate he specifically focused on the notion of "cleanliness".
