History
During the Spanish Colonization of Philippines, a native leader named "Dionisio" had cleared the forest land to create a settlement called "Lakdayan". In 1877 Spanish arrived and renamed "Lakdayan" to "Dionisio" in the honor of humble fisherman founder of the settlement. Spanish converted the natives and appointed St. Vincent Ferrer as Patron Saint of the settlement. Spanish set up the municipality at Concepcion, of which Dioniso was a part of. During Spanish times, the head of the local government of Concepcion was titled "Kapitan" (captain) and the subordinate leaders in San Dionisio were titled "Tenientes" (lieutenant) and hereditary Cabeza de Barangay (head of barangay). Eventually Sara was carved out of Concepcion to establish an eponymous municipality, which also included Dionisio as one of the constituent barangay of Sara. In 1920, San Dionisio municipality was established after carving it out of Sara municipality.
