"Slavery shaped the Americas for four centuries, blighting the entire hemisphere. The long struggle to dismantle it did not happen only in the U.S. or only in the South; in fact, in Cuba, Puerto Rico and Brazil it continued for decades after the U.S. Civil War. Simple narratives such as 'California banned slavery at its founding' and 'slavery ended in 1865' obscure much of its connection to this larger story. What happened to California illuminates the unevenness of abolition and the many false promises of freedom. It also serves as a reminder of the need for a wider lens when thinking about enslavement and freedom throughout the Americas today."
