Ā'ana and Ātua districts. Since then, the three political districts of Upolu have been called Ātua, Ā'ana and Tuamasaga. Prior to the reign of Queen Salamasina, the Tui Atua was held at different times by the ranking alii of Atua, including Lufasiaitu and Mua'iteleloa of Fagaloa, Leutele of Falefa (known as Tui Atua Leuteleleiite), and the tulafale-alii polities of Fuataga and Tafua in Aleipata. From the first Tui Atua to Queen Salamasina and then from her to her descendants, the title has passed down along these lineages according to the prevalent power of the time. Since the rise of the tama-a-aiga'' Tupua Tamasese and later, Mata'afa in the late 1700s, the Tui Atua mantle has remained exclusively between these two, with the exception of Malietoa Vainuupo, Malietoa Moli and Sualauvi I holding it in the aftermath of multiple conflicts.
