Tui Manuʻa
Tui Manuʻa was the title of the ruler or paramount chief of the Manuʻa Islands in present-day American Samoa, which expanded to become the Tui Manuʻa Confederacy, sometimes called the Samoan Empire. Samoan expansionism and projected hegemony in Oceania began with the founding of the Tui Manuʻa title. Traditional oral literature of Samoa and Manuʻa talks of a widespread Polynesian network or confederacy (or "empire").
