Passage: Tonga is a constitutional monarchy. Reverence for the monarch replaces that held in earlier centuries for the sacred paramount chief, the Tuʻi Tonga. Criticism of the monarch is held to be contrary to Tongan culture and etiquette. King Tupou VI (a descendant of the first monarch), his family, powerful nobles and a growing non-royal elite caste live in much wealth, with the rest of the country living in relative poverty. The effects of this disparity are mitigated by education, medicine, and land tenure.

Question: Who is the sacred paramount chies the the monach replaced?
Tuʻi Tonga
