Slavery seems to be the most unnatural thing for a human being but, paradoxically, it survived though thousands of years. Historians can’t say when and where slavery appeared but, according to them, it might be as old as civilization itself and it throve anywhere in the world regardless of religious beliefs and cultural values of the people.

Ancient Greece is known as the birthplace of the first democracies and greatest philosophers of the world. Slaves however were very common there, too, and no democrat had ever demanded abolishing of the institution of slavery. There were war slaves, piracy slaves and people who were enslaved for debts. They worked on farms and mines. Slaves who worked in wealthy households felt privileged as usually their work was not very hard and they were treated better.

In general, slavery in Ancient Greece was not as cruel as in lots of other parts of the world. A slave in Greece had no human rights, but his owner was not allowed to kill him at least. There was also a vague hope to gain freedom – some owners freed their slaves for good and devoted service. There was even the precedent of granting citizenship to a former slave.
