Amlan started as a settlement before the turn of the 19th century. By 1800, people from the provinces of Cebu and Bohol migrated to the wide fertile valleys of the municipality pursuing the Aetas, its original inhabitants, to the hills.
In 1840, the place was cleared for a community. At that time guavas called “Alman” were found abundant in the place. From the word “Alman” was derived the name “Amlan” for the settlement.
