Teha'apapa assumed the regency of her son Teriitaria with the support of Chief Oree, her great uncle by marriage.
It is clear that he was ousted during that decade by Mahine and Tenania, who eventually seized power over the island of Huahine.
[2] By October 1777, Captain James Cook noted that he was no older than twelve and recorded that his father had died in a battle against Puni, the chief of Borabora, who had conquered Tahaa and a few years before his first trip to the "Society Islands" in 1769, Raiatea.
[8] In January 1791, while in Tahiti, James Morrison (mutineer) reported having received information from the inhabitants of Huahine regarding Omai.
They informed him that "the Musquetts are in possession of a Chief who was his Friend (Calld Tennanea, brother to Tayreetarieea king of Hooaheine)".
[9] It is likely that the person mentioned by Morisson was the Ari'i whom James Cook met in 1777, although the relationship with Tenania, brother of Mahine, is somewhat erroneous.
[10][11] John Turnbull, a British navigator and merchant, arrived in Tahiti on September 24, 1802, and stayed for about a month.
[17] On November 11, 1808, English missionaries landed on the island of Huahine due to an insurrection against Pōmare II in Tahiti.
She was reckoned as Supreme Chief or "Arii rahi" on the island of Huahine and was intended to be the wife of King Pomare II.
[21] Later writings will confirm that he became Moeore, the chief of the district of Atea, on the east coast of the small island of Huahine.
[23] During the English missionaries' stay on the island of Huahine, a strategic alliance was forged between the Tamatoa and Pomare dynasties.
On this occasion, gifts were presented to eight chiefs of the island of Huahine: Hapapa, Nohorae, Tɛnanea, Turaeare, Tɛmare, Tɛehutu, Taroaare, and Taraemano (Tehaapapa, Nohorai, Tenania, Turaiarii, Temarii, Teihotu, Taaroaarii, Teraimano).
It is known that Teriia'etua was around 15 or 16 years old at the time of her death, which occurred prior to her half-brother, Pomare II, desire to embrace Christianity around 1812.
[20] In a letter dated November 16, 1810, addressed to the English missionaries, Pomare II recounted an attempted seizure of the ship Hope, commanded by Captain Chase, while it was docked at the island of Huahine.
This plan had been proposed by the chief, Tapoa I, who was present on the island, awaiting favorable winds to sail to Moorea in order to support Pomare II.
However, Pomare Vahine refused to involve the government of Huahine and responded to Tapoa I that if he intended to seize the ship, he should do so at Raiatea instead.
Pomare II reported in his letter that shortly after Tapoa’s departure, Teha'apapa I died on July 25, 1810.
He reports that the Chief Tapoa I had proposed the seizure of the ship Hope to the "old queen", who mainly ran the government.
In a document dated July 16, 1849, genealogist Taitete Mare provided details of the descendants of Tehaapapa I, with "v." denoting "vahine" (female) and "t." denoting "tane" (male): "Ma'ua took to wife Tetuanuimarama, sister of Tereroa and they had Rohianuu [...] Rohianuu took to wife Teioatua v. and begat Teriitaria.
She governed the island of Huahine with the main chiefs Mahine and Hautia on behalf of her sister Teriitaria II.
She died on December 16, 1834, in Huahine at the age of approximately 45, and was married to No, also known as Maitui, as recorded by missionary Charles Barff and his companion Thomas Nightingale..[35][36][37][38] Mare cited the fourth daughter of King Tamatoa III, Teritoiterai, who had been omitted from missionary John Davies' list dated November 28, 1808.
Puni, who had two wives and three concubines, had previously married Tereroa's sister, but she had died some time earlier.
