Dinalungan

Dinalungan traces its roots as a barrio that was part of Casiguran,^[6] which experienced numerous provincial transfers since the Spanish colonial period. The area was annexed by Nueva Ecija in 1818 and was later made part of Nueva Vizcaya in 1839.^[7] It then belonged to the El Príncipe District of Nueva Ecija beginning in 1856.^[8] During the American occupation, Casiguran became part of Tayabas (now Quezon) in 1902, briefly merging with Baler from 1906 to 1907.^[9][10][11] Though it was transferred back to Nueva Vizcaya in 1918, Casiguran was ultimately returned to Tayabas in 1946.

On June 18, 1966, barrios Simbahan and Dinalongan and sitios Abuleg, Bungo, Balante, and Nipoo were separated from Casiguran to form the new municipal district of Dinalungan (Dinalongan), by virtue of Republic Act No. 4757. Barrio Dinalongan was designated as the seat of municipal government. The first set of local officials were elected in the following 1969 elections.^[12] At the time of its creation, Dinalungan was part of the province of Quezon under its sub-province of Aurora until the latter was converted into a province on August 13, 1979.^[13]

With only a year left in his last constitutionally allowed term as president, Ferdinand Marcos placed the Philippines under Martial Law in September 1972 and thus retained the position for fourteen more years.^[14] This period in Philippine history is remembered for the Marcos administration's record of human rights abuses,^[15][16] particularly targeting political opponents, student activists, journalists, religious workers, farmers, and others who fought against the Marcos dictatorship.^[17] In Dinalungan during the early 1980s, things took a particularly violent turn after farmers organized a rally against a landowner who attempted to claim their farms, seeking help and support from the nuns at the Carmelite mission that had been established there.^[18] However, the military accused the Carmelites of working with the NPA, and even hunted down the convent's caretaker and one of the church workers.^[18] Young men started disappearing from the farms,^[18] and rumors begun to spread that they had been victims of extrajudicial killings by Marcos' forces.^[18] Some of Dinalungan's male population opted to join the anti-Marcos resistance at this time, rather than be killed without having done anything.^[18]

According to the Philippine Statistics Authority, the municipality has a land area of 316.85 square kilometers (122.34 sq mi), ^[19] constituting 10.07% of the 3,147.32-square-kilometer- (1,215.19 sq mi) total area of Aurora.

Dinalungan is situated 87.76 kilometers (54.53 mi) from the provincial capital Baler, and 340.07 kilometers (211.31 mi) from the country's capital city of Manila.

In the 2024 census, Dinalungan had a population of 12,552 people.^[28] The population density was 40 inhabitants per square kilometer (100/sq mi).
