Salamasina, the daughter of Tui A'ana Tamalelagi and a descendant of the Tu'i Tonga. She became the first sovereign of all Samoa. Throughout most of Samoa's history, the root cause of civil unrest was the struggle for titular supremacy among these families.The senior of the two, Sa Tupua dominated the office since the time of its titular ancestor, Queen Salamasina, in the 1500s. Sa Malietoa rejoined at the beginning of the 19th century, coinciding with the collapse of Manono's dominance and the arrival of British missionaries. Both the Tama-a-Aiga Tupua Tamasese title and the pāpā Tui Atua mantle are currently held by Samoa's former Prime Minister and Head of State, His Highness Tui Atua Tupua Tamasese Efi. Origins of Tupua The origins of the Tupua (later Tupua Tamasese) title is found in the genealogical line of succession tracing back to the rule of Queen Salamasina. Her descendant, Fonoti, won the civil war that led to his installation as King of Samoa. His son and successor, Muagututi'a, married Fenunu'ivao, daughter of Leutele of Falefa. Because they had no children of their own, they adopted Fenunivao's nephew Fuiavailili (son of Fuimaono of Salani) as their son. As the successor of King Muagututi'a, the orators of Tumua - the orator polity of Upolu based in Lufilufi and Leulumoega - questioned who this child was to assume such an important mantle and whether he possessed the necessary genealogical links to the great families of Samoa in order to be worthy. This inquiry is known as when "na saesae laufa'i ai Tumua" (lit. when Tumua systematically 'ripped the leaves of the banana tree' to examine the child's lineage). "E tua Mulinu'u ia Falenu'utapu, tatala le lafo o Manuō. E tua Vainiu i Aleipatalemele, tatala le lafo o Molio'o. E tua Vaie'e i Nofopule, tatala le lafo o Iuli. E tua Vailiili i Laloaoa, tatala le lafo o Moe'ono. Toe tua Vailiili i Salani ma Olofesula, tatala le lafo o Tofua'iofoa. Tua o Salani ma Olofesula i Falefasa, tatala le lafo o Talolema'agao. Toe tua o Falefasa i Faleniu ma Faletoi i Saoluafata, tatala le lafo o Fa'autagia. One faapea loa lea Tumua, o le tama e tele ona aiga, o le Tama a Aiga." - Orators of Tumua. Through this careful process, it was revealed that Fuiavailili's biological father Fuimaono was both a relative of Fenunu'ivao and also a direct descendant of Queen Salamasina's second
