History
The municipality of Mallig was named after the Mallig river that traverses it. The area was first mentioned by Fray Pedro de Santo Tomas as the area to which the Irray/Gaddang fled after the revolt of Dayag and Catabay in 1621 in what is now Ilagan City. In 1939, then President Manuel L. Quezon declared the westernmost part of the province as a resettlement area, historically known as the Mallig Plains Resettlement Area. From then on, the influx of settlers from the Central Plains and the Ilocos Region encouraged more other settlers to migrate westward in these Kalinga-dominated plains. Mallig was created by virtue of RA 678 authored in 1952 by congressman Samuel F. Reyes. The act was approved on April 8, 1953 with the former barrio Olango as the seat of government. The territory comprising Mallig was taken from several neighboring towns:
from Ilagan City: barrios of Casili, Olango Primero, Olango Segundo, San Jose Nuevo, and Manano
from Tumauini: barrios of Barucbuc, Siempre Viva, Bimmonton, Pasurgong, Manga, and Settlement No. 1
from Santo Tomas: barrios of Abut and Minagbag
Mallig was never a ready haven and abode for the migrants at the beginning, particularly because of the hostile natives who formerly dominated the area, and also because of the occurrence of endemic malaria. It took the settlers gradual adaptation and acclimatization before they finally convinced their relatives and other migrants to settle permanently.
