History
Early history
Long before its formal creation as an independent province, Quirino was the forest region of the province of
Nueva Vizcaya, inhabited by tribal groups known as the
Negrito
The term ''Negrito'' (; ) refers to several diverse ethnic groups who inhabit isolated parts of Southeast Asia and the Andaman Islands. Populations often described as Negrito include: the Andamanese peoples (including the Great Andamanese, th ...
s. They roamed the
hinterlands and built their huts at the heart of the jungle. Aside from the Negritos, the area was also inhabited by
Ilongot people, who were feared for their headhunting raids against enemy tribes and Spanish-controlled settlements. Throughout the period of Spanish colonization, the province was one of the few remaining unconquered areas in the Philippines due to its remoteness, having only seen a Spanish military expedition in 1848 and the brief presence of Spanish missionaries in 1891.
Colonial era
During the American period, the territory of Quirino was administered by the province of Isabela before Congressman Leon Cabarroguis of Nueva Vizcaya pushed for its return to Nueva Vizcaya by authoring Republic Act No. 236, which was signed into law in 1948.

On June 21, 1969, Republic Act No. 5554 was enacted, amending RA 4734, and creating the municipality of
Cabarroguis (now the provincial capital town), which was taken from portions of Diffun, Saguday, and Aglipay.
Republic Act No. 6394, authored by then-Congressman Leonardo B. Perez (
Nueva Vizcaya–Lone), was passed on September 10, 1971, further amending RA 5554 and separating the sub-province of Quirino from its mother province, Nueva Vizcaya, constituting it into a
regular province.
The province of Quirino was formally established on February 10, 1972, upon the assumption to office of the first elected provincial and municipal officials headed by Dionisio Sarandi as Provincial Governor.
On February 25, 1983, Batas Pambansa Blg. 345 was enacted, creating within Quirino the municipality of
Nagtipunan, a division of the municipality of

Marcos dictatorship era
The beginning months of the 1970s marked a period of turmoil and change in the Philippines, as well as in the localities which would later become the Province of Quirino.
In February 1972, the efforts of Quirino's legislators finally managed to see its establishment as a separate province.
During his
bid to be the first Philippine president to be re-elected for a second term, Ferdinand Marcos launched an unprecedented number of public works projects that caused the Philippine economy to take a sudden downwards turn known as the

in September 1972 and thus retained the position for fourteen more years as a dictator.
In Quirino, one of the most significant events of this period were the logging concessions in the areas of the Sierra Madre region awarded to various
Marcos cronies, which marked the beginning of widespread deforestation and other environmental problems in the province.
When the
1986 snap election came along, Quirino was noted as a site of political violence with the
murder of UNIDO opposition party organizers Francisco Laurella and Fernando Pastor Sr., and Pastor's son Fernando Pastor Jr., later attributed to Marcos party-mate and Quirino province assemblyman
Orlando Dulay, who was convicted of the three murders in 1990.
