Demography The Buol-speaking people live in the districts which now comprise the Buol regency (in Central Sulawesi Province) which borders the Gorontalo province. Formerly mountain dwellers, the Buol now live in scattered villages on the central part of the northern peninsula, to the north-west of the Gorontalo province. The history of the Buol region is one of the rise and fall of small kingdoms and their occasional confederation into larger entities for defense and conquest. Sometimes, the Buol people are treated as a subgroup of the Gorontalo people group due to cultural and linguistic similarities. The Buol language is part of a larger linguistic grouping called the Gorontalic family which also includes the Bintauna, Kaidipang, Bolango, Gorontalo, Lolak and Suwawa languages.
