Black Lives Matter & the Legacy of Systemic Racism

Join us on Wednesday, November 18 at 7pm for a presentation "Race-based real estate developments in Jefferson County, Colorado".

Live Zoom-based online talk.
Subdivisions in Jefferson County, Colorado developed from the late 1910s to the early 1950s, often had covenants that included race-based exclusionary language. The covenants were rules that government who and who could not own the houses. The covenants were legal documents (now voided) that were approved by Jefferson County government officials. An example of this language is: “No persons of any race other than the Caucasian race shall use or occupy any building or any lot.”
