The Hill District is a grouping of historically African American neighborhoods in the City of Pittsburgh, Pennsylvania. Beginning in the years leading up to World War I, "the Hill" was the cultural center of black life in the city and a major center of jazz. Despite its cultural and economic vibrancy, in the mid-1950s a substantial area was slated for redevelopment, displacing about 8,000 individuals.
