Tamahàis the ceremonial name of the daughter of the Tuûi Tonga's (King of Tonga's) sister. The eldest sister of the Tuûi Tonga (King of Tonga) is usually called the Tuûi Tonga Fefine.
The special title of TamahÃÂ is given to the eldest daughter of the Tu'i Tonga Fefine and a chief of one of the Falefisi (Tu'i Ha'ateiho or Tu'i Lakepa). The TamahÃÂ had the highest social status in the land, because she was fahu ("above the law") to the Tu'i Tonga. However, she did not have the highest societal rank (ha'a). The TamahÃÂ did not rule the land and had no real power within the societal structure.
