In simple terms, racism is the belief that distinct human races exist and that one race is superior to another. This definition is generally agreed by the Oxford English Dictionary, Merriam-Webster Dictionary (USA) and the Macquarie Dictionary (Australia).
1932 as a noun, 1938 as an adjective, from race (n.2); racism is first attested 1936 (from French racisme, 1935), originally in the context of Nazi theories. But they replaced earlier words, racialism (1871) and racialist (1917), both often used early 20c. in a British or South African context.
