As well as being active in defending the independence of teachers, and opposing a communist takeover of the New York Teachers' Union, Dewey was involved in the organization that eventually became the National Association for the Advancement of Colored People (NAACP).
He directed the famous Dewey Commission held in Mexico in 1937, which cleared Leon Trotsky of the charges made against him by Joseph Stalin,[REF] and marched for women's rights, among many other causes.
