Historic buildings such as Independence Hall, Liberty Bell Center, and Philadelphia City Hall are reminders of the city’s rich past. In the 19th century, Philadelphia became an important center for industry and railroads, attracting many European migrants. In the first half of the 20th century, many African Americans camelive from the South. After the decline of local industry, Philadelphia experienced a period of decline, but since the late 1990s, many neighborhoods have begun a process of gentrification. Since the 1960s, the city has been controlled by Democrats. In January 2016, Jim Kenney became mayor.
