Municipalities

Diffun is the gateway to the Province of Quirino. Majority of its people were comprises of farmers and diversity of professionals. Its main products are rice, corn, bananas and other root crops. With regards to education, it has 2 National High Schools and a College University. 

Prior to the advent of settlement, Cabarroguis is a vast forested area and form parts of the municipalities of Saguday, Diffun and Aglipay. It is originally occupied by the Aetas and later displaced by the Ilongot tribe because the Aetas are known of their nomadic characters. Many years later, permanent settlement were made by different civilized ethnic groups like Ilocanos, Tagalog and others in search of good fortune in this virgin land. As the population and settlement increases, regular barrios were created. These are the barrios of Zamora, Banuar, Burgos, Del Pilar, Dibibi, Eden, Villamor and five (5) more sitios of Villapeña, Villarose, Tucod, Calaocan and Dingasan at the municipality of Aglipay: barrios of San Marcos, Gundaway and portion of Mangandingay at the municipality of Diffun and the other part of Mangandingay at the municipality of Saguday. The above stated barrios of different municipalities became the territorial jurisdiction of Cabarroguis by virtue of Republic Act No. 5554 enacted by the Philippine Congress authored by then Honorable Senator Leonardo Perez on June 21, 1969. The newly created municipality of Cabarroguis was named in honor of the late Congressman of Nueva Vizcaya, Honorable Leon Cabarroguis. 

Saguday was a barrio of the Municipality of Santiago, Isabela, however, upon the final settlement of the boundary dispute between Isabela and Nueva Vizcaya, Saguday became a regular barrio of Diffun by virtue of an Executive Order No. 386, issued by then President Elpidio Quirino. 

Saguday was initially a sixth class municipality. Barangay Cardenas was created in 1980 pursuant to Sangguniang Bayan Resolution No. 02, while Barangay Gamis was founded in 1981, pursuant to Resolution No. 05. At present, Saguday is a 5th Class Municipality due to its limited income which is attributed to scarce resources.

Upon the creation of the Municipality of Saguday, the urban core was divided into two barrios: District I now Barangay Magsaysay has been the seat of the Municipal Government from then up to present, and District II now Barangay Rizal.

The municipality of Aglipay, Quirino was named in honor of the late Gregorio Aglipay, the head of the only existing religious sect in the community at that time. It was created through Executive Order No. 368 signed by the then President Elpidio Quirino on 11 November 1950 which reorganized the municipalities and municipal districts of the province of Nueva Vizcaya. It became one of the ten municipalities of the said province with an area of approximately forty one thousand one hundred twenty six (41,126) hectares. Its first seat of government was at Barangay Guinalbin with the late Hon. Gregorio Divina as its first appointed town Executive. It was then composed of only six barangays and inhabited mostly by Christians from the lowlands comprised mostly of Ilocano’s with some non-Christians tribes. 

Maddela was formerly called Pinappagan which was formerly a territory of Nueva Vizcaya Province. It was first settled by the Ilongot tribes. In 1919, several Ilocanos headed by a certain Vicente Velasco explored the area and formed settlement villages.

Around 1922, Lt. Quintin Alcantara organized a military government and built a trail connecting Nueva Vizcaya and southern Isabela. In 1928, Pinappagan was created as a municipal district town of Bagabag, Nueva, Vizcaya with Eusebio Martin as the first municipal president (mayor).

The Municipality of Nagtipunan was formerly a part of Maddela

It was created on February 25, 1983 by virtue of Batas Pambansa No. 345 and approved in a plebiscite held on September 24, 1983.

The town’s name was derived from the native word meaning “convergence point,” in reference to several major tributaries of the Cagayan River in Aurora, Nueva Vizcaya and Qurino meeting at points within this area.
