Province of Ilocos Sur - Bicentennial Anniversary
Ilocos Sur is a province located in the Ilocos Region in Luzon. The
Ilocos Region was already a thriving, fairly advanced cluster of
towns and settlements when the Spanish explorer, Juan de Salcedo,
and members of his expedition arrived in Vigan on June 13, 1572.
Augustinians came to conquer the region through evangelization. They
established parishes and built churches that still stand today.
Three centuries later, Vigan became the seat of the Archdiocese of
A royal decree dated February 2, 1818 separated the northern section
of Ilocos which became the province of Ilocos Norte. The southern
portion, called Ilocos Sur, included the northern part of La Union
and all of Abra. It was the union of portions of Ilocos Sur from the
Amburayan were taken from the Mountain Province and incorporated
with Ilocos Sur.
The history of Ilocos Sur was characterized by revolts in protest
against tributes and forced labor. The best-known of these revolts
was the Ilocos Revolt (1762-1763) led by Diego Silang. It was a
revolt of the masses against the Babaknangs and the alcalde-mayor of
Vigan. After Silang’s assassination, his wife Gabriela continued the
fight until she was hanged publicly in 1763. On March 25, 1898,
Isabelo Abaya started a revolt in Candon and raised a red flag in
the town plaza. This was the start of several
revolutions in the Ilocos Region.
Ilocos Sur figured prominently during the Philippine Revolution in
1896 and Philippine-American War in 1899. The Battle of Tirad Pass
elevated the heroic death of General Gregorio del Pilar who covered
the retreat of General Emilio Aguinaldo to the Cordilleras and to
Palanan. During World War II, the Battle of Bessang Pass in Candon,
fought between the forces of General Yamashita and U.S. 21st
Infantry, was the climax in the fight for liberation.
