In this groundbreaking work, sociologist James W. Loewen, author of the classic bestseller Lies My Teacher Told Me, brings to light decades of hidden racial exclusion in America. In a provocative, sweeping analysis of American residential patterns, Loewen uncovers the thousands of 'sundown towns' - almost exclusively white towns where it was an unspoken rule that blacks weren't welcome - that cropped up throughout the twentieth century, most of them located outside of the South.
