Sure, but this is an awfully broad area to talk about, with many hundreds of cultures. I'm most familiar with North America, so I'll give you a few examples from there. At the time the Europeans arrived in the great lakes region, the idea of 'raising the dead' existed, wherein dead loved ones could be 'replaced' by the capture of the members of other nations during wartime who would be forced to adopt the name of a dead loved one. Given the loss of autonomy and the force involved this is sort of like slavery.

Slavery was also practiced on the west coast, with nations like the Modoc of CA/OR trading slaves captured in combat and Inuit nations of Alaska practicing slavery. Unlike the slavery that came with Europeans, however, slavery was not a heritable condition and a slave's children would be members of the nation that enslaved their parents.

Aztecs, Mayas, Incas, Taínos, they all had slavery. The specifics of each culture of what slavery was, what one could and couldn't do with slaves, were different, but they all had slavery of some kind.
