African Americans migrated to the city, many first working for the railroad, which had a terminus here. It developed as a predominantly African-American neighborhood because discriminatory home sale laws in other areas excluded black people.
With a succession of majority populations as new residents settled in the city, Five Points in the first half of the 20th century became known as the ' Harlem of the West'. Rino, Union Station North, Clement, Old San Rafael, Curtis Park, Arapahoe Square, and Ballpark neighborhoods are located within the boundaries of the larger Five Points neighborhood. The neighborhood was home to a number of Denver's leaders, housing mayors, governors, and prominent business people, as well as middle-class laborers. Five Points came to historical prominence from the 1860s through the 1950s.
