Tu'i, also spelled more simplistically Tui, is a Polynesian traditional title for tribal chiefs or princes. In translations, the highest such positions are often rendered as "king". For details, see the links below various polities. Traditionally, a Tui is an equivalent of God title. Origin of Tui is believed to be Tui Manu'a (the title given to the son of the Polynesian God Tagaloa, and therefore Tui were viewed as living Gods).
