The United States territory of Guam is divided into nineteen municipalities, called villages.

In the 18th century, there were six parishes on Guam: Hagåtña, Hagat, Humåtak, Malesso', Inalåjan, and Pago.

Prior to Spanish colonization, Chamorro people regularly held village celebrations.

After adopting Christianity, these celebrations became festivals (fiestas) in honor of the patron saint of each village.

The current division of Guam into municipalities took place in the 1920s under United States Navy Administration.
