Leasina County is a county in the Western District in American Samoa. The name of the county, Leasina, is derived from the Samoan language and translates into English as âÂÂWhite".
The official county name was changed to Leasina ma Aitulagi County following the 2022 American Samoan constitutional referendum.
Leasina contains the villages of Aûasu and Aûoloau in the northwestern part of Tutuila Island. The principal place is the village of Aûoloau, where the powerful Fuimaono resides. At Aûasu Bay, also known as Massacre Bay, French sailors were massacred in 1787. Aûoloau is also referred to as Aûoloaufou, which means "New Aûoloau", while the abandoned village on the north coast, on Aûoloau Bay, is called Aûoloautuai, meaning "Old Aûoloau". Similarly, the village of Aûasu is known as Aûasufou (âÂÂNew AûasuâÂÂ). The original village, located on Massacre Bay, is called Aûasutuai (âÂÂOld AûasuâÂÂ).
During World War II, a communications and radar station was built atop TutuilaâÂÂs central mountain ridge, above the village of Aûoloau. The project required clearing a square mile of plateau land and constructing a long, winding mountain road that climbed up from the south coast highway at Mapusaga.
In 1976, Lualemaga Faoliu, the senator representing the county and a native of Aûoloau, was shot and killed during a family trip to the island of Savaiûi.
Leasina County was first recorded beginning with the 1912 special census. Regular decennial censuses were taken beginning in 1920.
