The University of Northern Philippines holds the distinction of being the first state university in Northern Luzon. It was created through the enactment of Republic Act 4449 authored by the late Congressman FLORO S. CRISOLOGO. Approved on 19 June 1965, the Act converted the Ilocos Sur School of Arts and Trades, in the municipality of Vigan, province of Ilocos Sur, into this University.
The governance of this University is vested in a Board of Regents. The first board was constituted on October 14, 1965.
The origin of this University can be traced through the following dates:
