Records of slavery in Ancient Greece date as far back as Mycenaean Greece. It is certain that Classical Athens had the largest slave population, with as many as 80,000 in the 6th and 5th centuries BC;[113] two to four-fifths of the population were slaves.[114] As the Roman Republic expanded outward, entire populations were enslaved, thus creating an ample supply from all over Europe and the Mediterranean. Greeks, Illyrians, Berbers, Germans, Britons, Thracians, Gauls, Jews, Arabs, and many more were slaves used not only for labour, but also for amusement (e. g. gladiators and sex slaves).
