W. E. B. Du Bois was a sociologist and activist who fought for the political and social rights of African Americans.

William Edward Burghardt Du Bois was an African-American sociologist, historian, civil rights activist, pan-africanist, author and editor.

Racism and discrimination were the frequent targets of Du Bois's polemics, and he loudly protested against lynchings, Jim Crow laws and discrimination in education. Du Bois made several trips to Europe, Africa and Asia. After the First World War, he surveyed black soldiers in France and documented widespread intolerance in the American military. His cause included people of color from all over, particularly the Asians and Africans in their struggle against colonialism and imperialism. He was an advocate of Pan-Africanism and helped organize several Pan-African congresses to free African colonies from European powers. Du Bois was also a feminist who supported the women's suffrage movement in the United States.
