I've been watching the Netflix show, Medici: Masters of Florence. When Cosimo de' Medici is exiled to Venice, he's given a woman named Maddalena as a slave; later, when he goes back to Florence, she continues to be considered his/the family's slave.

Obviously I don't expect much from a tv drama in the way of accuracy to Cosimo's life/personality, but in the case of the broader social context - is this accurate? Was the enslavement of Italians by other Italians happening during this period?
