Clans, Tribes, and the State: How Kin-Group Policy Shapes Who Assimilates

Whether a state suppresses or utilises kin‑based groups (clans, tribal networks) is a durable policy choice that structures social trust, administrative costs, and the capacity to absorb migrants; historical examples include Chinese emperors leaning on clans or using eunuchs, and Islamic polities shifting from tribal armies to slave forces under the Abbasids. These institutional trade‑offs produce long‑run differences in individualism, cohesion, and how newcomers are incorporated. — Recognizing kin‑group policy as a deliberate state choice reframes immigration debates from cultural temperament to institutional design and capacity.
