>To modern Westerners, the use of such a kinship metaphor suggests and is believed to reflect genuine nurturing and closeness; however, in Africa and elsewhere it conveys an entirely different meaning: authority and subordination.
>Villagers, forming a gauntlet and armed with clubs, fire-brands, sticks, and other weapons, greeted the prisoners and rained down on these hapless individuals blows designed to inflict pain but not to kill This was often followed by torture and public humiliation and then deliverance to the grieving families, whose "matrons then chose either to adopt or to execute them," or both
If you look at pages 11-13, there's a discussion of ritual torture to prevent captives from escaping. 13-14 deal with the torture and execution of unruly captives. 15-16 deal with the etymological relationship between "slave" and "pet/livestock" in Iroquonian languages like Mohawk. Pages 17 and 18 discuss people preferring suicide to capture and the sexual exploitation of female captives.
>The ways in which captives were treated differed widely among Native American groups. Captives could be enslaved for life, killed, or adopted. In some cases, captives were only adopted after a period of slavery. For example, the Iroquoian peoples (not just the Iroquois tribes) often adopted captives, but for religious reasons there was a process, procedures, and many seasons when such adoptions were delayed until the proper spiritual times.
>In the cultural practices of the Iroquoian peoples, also rooted in a matrilineal system with men and women having equal value, any child would have the status determined by the woman's clan. More typically, tribes took women and children captives for adoption, as they tended to adapt more easily into new ways.
