The
Aesti (also
Aestii or
Aests) were an ancient people first described by the
Roman historian
Tacitus in his treatise
Germania (circa 98 CE). According to Tacitus,
Aestui, the land of the Aesti, was located somewhere east of the
Suiones (Swedes) and west of the
Sitones (possibly the
Kvens), on the
Suebian (Baltic) Sea. This and other evidence suggests that Aestui was in or near the present-day Russian enclave of
Kaliningrad Oblast (previously
East Prussia).
