The Q was, until the mid-50s, Baltimore housing and school were was racially segregated by law and "negroes" could only live in three neighborhoods. What were they?
The A:
The East, West and South sides of town.
A PA librarian found
this article, "The Transnational Contexts of Early Twentieth-Century American Urban Segregation," which in spite of the horrible title turns out to be quite a worthwhile read, full of interesting info. In it we learn that the law didn't dictate where "Negroes" had to live, exactly. Instead, "white" people segregated themselves into the gay-sounding "favored fan" of the North, and in 1911 the Baltimore City Council passed the West Segregation Ordinance* which apparently allowed neighborhood associations to have racially restrictive neighborhood covenants. However, of all the 1910's white housing projects, only Guilford's covenant (and possibly Northwood's, see comments) was in-your-face enough to specifically include restrictions on resale to Negroes in the home deeds (a tip Olmstead et. al got from real estate developers in Chicago).
The U.S. Supreme court struck down racial real-estate covenants in 1917, so in Baltimore racial housing segregation was on the books for just four years, though the "marketized system of urban residential segregation-- along with its consequences for unequal access ... and unequal exposure to toxins and the criminal justice system-- remains virtually unscathed."
ps. Why did the same real estate developers who didn't want to put racial language in the deeds for Roland Park feel more emboldened for their next construction project? Apparently July 4, 1910 was
Jack Johnson's victory over white boxer James Jeffires, who came out of retirement solely to prove "that a white man is better than a Negro." Jeffries' loss incited white people to riot nationwide, and local whites ("officers of neighborhood associations, letter writers and signers of petitions") brought pressure to lawmakers address the "Negro invasion."
