I'm conducting research about the Black community following the 1874 Chicago fire. Primary sources document significant residential shifts after the city's destruction. To be sure, it seems the beginnings of the "Black Belt" emerged shortly after the '74 fire. Currently, I'm trying to determine whether something similar to restrictive covenants perhaps restricted where Black Chicagoans could or did live at the time. I've looked over Du Bois's 1896 Philadelphia study and a few other Progressive-era texts, but haven't found anything yet. Does anyone have advice about where to start/find sources? Or was there no such contract in existence until the 1920s?
Thank you in advance for your help!
