The historical relationship between American urbanization, industrialization and the emergence of the civil rights movement is examined in this thesis in order to establish why the African-American Civil Rights Movement occurred. The book discusses many factors that were fundamental to causing the rise of the civil rights movement. It begins with a brief introduction to the African-American's political, economic and social conditions since the American Civil War and goes on to consider the effects of the two Great Black Migrations in which millions of black Americans moved to the big industrial cities and began to learn how to make effective use of their voting rights to protect their own interests. Finally the book examines the effect of the Second World War and also the role of the Supreme Court.
