The Municipality of Tupi in the past even during the Pre-Hispanic era was believed to be solely inhabited by B?laans and Moslems. The B?laan who composed the greater population occupied most of the area, while the Moslems occupied the areas along the rivers traversing the community. During that time, Tupi used to be a wide area of tropical virgin forest with only a few patches of clearing where the inhabitants used to settle. Food was solely derived from the forests and rivers. No roads and permanent human settlement exists. The inhabitants during that time lived in a nomadic way because food crops need not be grown and clean water is found everywhere.
