In this lecture, Professor Holloway documents the "Great Migration," beginning in the first decade of the twentieth century and continuing with increasing pace until the mid-1920s. During this time, black Americans relocated from the rural South to the urban North. As Professor Holloway reveals, urban life in the North was frequently cruel and often difficult. The remainder of the lecture focuses on how whites' racial anxieties were manifested in the cultural realm, using D.W. Griffith's popular film Birth of a Nation.
