How did the iroqouis replace people who had been lost in battle?

The Iroquois replaced individuals lost in battle primarily through a practice called "adoption," where they would integrate captives from rival tribes or other groups into their society. This process involved not only taking in individuals but also giving them a new identity, including a new name and role within the community. Additionally, the Iroquois might also recruit individuals from neighboring tribes or encourage their own members to expand families, thus maintaining their population and social structure.
