What was slavery like in the Iberian Peninsula? Who was affected and how were they treated?
I'm a history student, and in my modern history course, it's mentioned that slavery existed in the Iberian Peninsula. It states that the master or owner had all rights except to kill or mutilate the slave. I can't remember exactly how long this lasted, but I think the Church condemned the practice. I've seen it mentioned in books before, but always in a rather cursory way; it's never really explored in depth.
Who were the slaves? Were they African slaves? Or were they Iberians who had been condemned? I know that some convicts were sent to the mercury mines, for example. Were they domestic servants, or did they perform these kinds of dangerous tasks? Were they generally well-treated despite their status, or were they frequently mistreated? So, to put it simply, what was it like?
