Najeeb M. Saleeby, The History of Sulu
“ The population of this whole group is generally estimated at 25,000. Of these, 15,000 live in Basilan itself. The inhabitants of Basilan proper are Yakans and Samals, while the adjacent islands are occupied entirely by Samals. The Yakans are the aborigines of Basilan and extend farther into the interior than the Samals.Basilan never enjoyed political independence. Before Spanish rule it was governed by Sulu datus and paid tribute to the Sultan of Sulu. Under the datus, subordinate Samal panglimas3 and maharajas4 had charge of the various communities or settlements. ”
