In the early 20th century, American Samoa's first Governor, Commander Benjamin Franklin Tilley, restructured these divisions for administrative purposes.

To enhance local governance, Governor Tilley selected prominent chiefs from these villages, appointing them as Pulenuu (mayors).

A resident of Tualauta County named Fagaima[4] caught a skipjack — traditionally reserved only for high chiefs — and prepared it for his meal.

Outraged, High Chief Letuli of Tualauta County ordered the destruction of Fagaima’s house and crops, as well as his banishment.

[5] In 1902, opposition to the copra tax arose among Tutuilans, especially within the Western District and notably in Tuālāuta County, which would later become a significant place for the Mau movement.

In response to this resistance, Governor Uriel Sebree detained three local chiefs to discourage their supporters and dismissed a Samoan judge who had submitted a protest petition to the U.S. Navy.

Governor Sebree described Samoans as “grown-up children who love form and ceremony.” In 1904, during formal assemblies, chiefs from both the Western and Eastern Districts appealed for a reduction in the copra tax and raised concerns about the government's expenditure of the collected funds.

Additionally, all the defendants were stripped of their titles, an action that was particularly offensive since the cession treaties had promised not to interfere with Faʻa Sāmoa.

Subsequently, President Truman instructed the Secretaries of the Navy and the Interior to collaborate on plans for this administrative transition.

Between 1970 and 2010, the population of American Samoa grew by nearly 40,000, with the Western District accounting for a significant portion of this growth, adding over 22,000 residents.
