After the Second World War, DuBois Joined the N.A.A.C.P. staff for another short period. However, his disillusionment with society had deepened, and he was ready to consider even more radical solutions than before. He had become increasingly convinced that racism was a world problem and not merely an American problem. The series of Pan-African Congresses which he had helped to organize forced him to see a connection between American racism and European imperialism in Africa. At the same time, communism was representing itself as the foe of both racism and imperialism, and for many of the oppressed peoples throughout the world the communist claim had become attractive. To the N.A.A.C.P. it seemed that DuBois's new "pink" ideas and associations were not good for its image, and it asked him to resign. The government charged DuBois with failing to register the "Peace Information Center", where he was employed, as an agent for a foreign principal. Although acquitted, the harassment deepened his cynicism and hostility. Finally, he became a communist, and he moved to Ghana in 1960. He died there in 1963. As a young scholar, DuBois had begun by believing that reason and research would dispel ignorance and prejudice. Obviously, prejudice was not so easily eradicated by reason alone. "The talented tenth," which was to lead the Afro-American community into the mainstream of American life, had not been successful. White bigots were especially antagonized by educated blacks. When DuBois had advocated black solidarity, it had failed to take root because the intellectuals had become alienated from the masses. The black bourgeoisie had been hindered by their color from assimilating into white society, and their newly acquired education, values, and middle-class style of life prevented them from returning to their people. Finally, DuBois's work with the N.A.A.C.P., while it achieved some significant results, failed to bring about the kind of structural social change he desired. Despairing of bring about racial advancement in America, DuBois decided to work for it in Africa. Marcus Garvey: The Trumpet of Pride
