American Samoa

1900 – present
TerritoryOceania

Unincorporated and unorganized territory of the United States comprising the eastern Samoan islands (Tutuila, Aunuu, and — after a separate 1904 cession — the Manuʻa group of Ofu, Olosega and Tau, plus Swains Island). Ceded to the US via the 1899 Tripartite Convention (Tutuila, formalized by a Deed of Cession signed by local chiefs in 1900) and the 1904 Deed of Cession of Manuʻa (ending the Tui Manuʻa paramountcy, already covered in the atlas as a separate record ending 1904). Remains a US territory continuous to the present, self-governing under its own constitution since 1967, with a locally elected government (the Samoan Fono) but no voting representation in the US Congress and no automatic birthright citizenship for those born there.

Remains an unincorporated United States territory; its people are US nationals and the 1900 and 1904 deeds of cession still anchor its status.
