| has gloss | eng: The order of succession to the throne of Tonga is laid down in the 1875 constitution of the south Pacific island nation. This constitution specifies that the succession is confined to the descendants of King Siaosi Tāufaāhau Tupou I, through his son Crown Prince Tēvita Unga and his son Prince Uelingatoni Ngū (all names in modern spelling). Tēvita Unga was an illegitimate son, but all of Siaosi Tāufaāhau Tupou's legal sons had died before; at the end both Tēvita Unga and Uelingatoni Ngū also died before him. It also established primogeniture, with male offspring having precedence over females. The Heir Apparent is styled by the title Crown Prince; other sons are styled Prince. All are addressed as "His Royal Highness". |
