Manabendra Nath Roy (born Narendra Nath Bhattacharya, better known as M. N. Roy; 21 March 1887 – 25 January 1954) was a 20th-century Indian revolutionary, philosopher, radical activist and political theorist. Roy was the founder of the Mexican Communist Party and the Communist Party of India (Tashkent group). He was also a delegate to the Communist International congresses and Russia's aide to China. In the aftermath of World War II Roy moved away from orthodox Marxism to espouse the philosophy of radical humanism, attempting to chart a third course between liberalism and communism.
