During the Spanish-Chamorro Wars of the late seventeenth century, settlements in Yigo included Hanom, Tarague, Hinapsan, and Upi (now Northwest Field).

The August 1679 defeat of the CHamorus at Hanom by a force of Spaniards and their allies from Nisihan led by José de Quiroga y Losada was one of the fiercest battles of the conflict.

[2] In the early nineteenth century, wealthy residents of Hagåtña began purchasing fertile land in Yigo for agricultural uses.

The area became known for producing cocoa beans, used to make hot chocolate for Hagåtña residents, as well as coffee, avocado, citrus, and copra.

Following the war, the population of Yigo soared, first as it accommodated displaced persons from the south and then non-Chamorus who moved to Guam.

The economy reoriented from agriculture towards the presence of Andersen Air Force Base and the population continued to grow with the construction of housing subdivisions throughout the village.
