Slavery
If there is one dark side of human evolution that is possibly worse than most, it’d be this one. Slavery was and still is a crime against humanity. However, slavery has some chapters we’re not quite as familiar with. For example, someone who owed a debt to another but could not afford to pay it would pay it off through slave labor. This was a common practice in Ancient Greece and even Egypt for a long time. Of course, some were not released from this and were kept as slaves even after paying their debt. Yet this was more uncommon. Overall, we practiced slavery in some form or another for at least 11,000 years now. Women were some of the most common slaves among the rich, especially in monarchies. They might also be taken as “wives” as spoils of war for invading armies too. Other people, more often than not poorer classes, were taken as property.
