It is generally believed that the Samoan Islands were originally inhabited as early as 1000 BC. Samoa was not reached by European explorers until the eighteenth century. The pre-Western history of Eastern Samoa (now American Samoa) is inextricably bound with the history of Western Samoa (now independent Samoa). The Manu’a Islands of American Samoa have one of the oldest histories of Polynesia, in connection with the Tui Manua title, connected with the histories of the archipelagos of Fiji, Tonga, the Cook Islands, Tokelau and elsewhere in the Pacific—all of which had once been under Manua’s occupation. Tu’i Manu’a from Manu’a ruled most of the Pacific, including Tonga, long before the Tu’i Tonga Empire. While Tu’i Manu’a ruled Tonga, the external influences came in the form of imperial activities, beginning with the Tu’i Pulotu empire in Fiji and followed by the Tu’i Manu’a empire in Samoa. In other words, Tonga was under considerable influence from the imperialism of both Fiji and Samoa. However, Tonga was able to free itself through bitter and bloody wars from the imperial domination of the Tu’i Manu’a — which eventually led to the formation of the Tu’i Tonga empire around AD 950 in the person of ‘Aho’eitu, the first Tu’i Tonga — whose father was a deified Samoan high chief, Tangaloa ‘Eitumâtupu’a, and mother a Tongan woman, Va’epopua, of great noble birth. This double origin entitled the Tu’i Tonga to hold both divine and secular offices.

In principle, the close cultural and historical interlinkages between Fiji, Samoa and Tonga were essentially elitist, involving the intermarriage between regional aristocratic families. Many years later, after Tonga freed itself from Samoa, the Tongans took rule over Samoa until Samoa freed itself. Manu’a was the only island group that remained independent. The islands of Tutuila and Aunu’u were politically connected to ‘Upolu island in what is now independent Samoa. It can be said that all the Samoa islands are politically connected today through the faamatai chiefly system and through family connections that are as strong as ever. This system of the faamatai and the customs of faasamoa originated with two of the most famous early chiefs of Samoa, who were both women and related, Nafanua and Salamasina.
