When California became a state in 1850, it entered the union as a state that would not allow slavery. That's the history most people know. But in reality, California did allow slavery and its early leaders sided with the South and the rights of enslavers through a litany of early laws. The effects of that racist foundation are still being felt by people of color in California today.

Located at the corner of Martin Luther King Jr. Way and Derby streets in Berkeley, The Rainbow Sign was a Black-centered space that was open to all — as a performance venue, a political organizing nexus and a legendary cafe. It saw dozens of high-profile Black luminaries walk through its doors, including James Baldwin, Nina Simone, Maya Angelou and Shirley Chisholm. The Rainbow Sign opened its doors in 1971, but was forced to shut down just six years later. Despite its short existence, the venue left an indelible mark on many young people in the community, including Vice President Kamala Harris.
