American historian who studied the American antebellum South and slavery. Phillips concentrated on the large plantations that dominated the Southern economy, and he did not investigate the numerous small farmers who held few slaves. He concluded that plantation slavery produced great wealth, but was a dead end, economically, that left the South bypassed by the industrial revolution underway in the North. By turning away from the political debates about slavery that divided North and South, Phillips made the economics and social structure of slavery the main theme in 20th century scholarship. Together with his highly eloquent writing style, his new approach made him the most influential historian of the ante-bellum south. His interpretation of white supremacy as the "central theme of southern history" remains one of the main interpretations of Southern history Less
