La Union and part of Mountain Province as his hacienda (estate), and was accorded the title of Justicia Mayor de esta Provincia de Ylocos (Province Mayor of Ilocos). In 1574, Salcedo returned to the capital of his encomienda (trusteeship), Vigan, bringing with him his soldiers and some Augustinian missionaries to pioneer the evangelization of the Ilocos region. He established a Spanish city for the purpose of controlling the neighboring country. Governor General Gómez Pérez Dasmariñas, in his account of encomienda dated in Manila on May 31, 1591, states: "The town of Vigan called Villa Fernandina consisted of Spanish settlers; a priest; a Justice Alcalde Mayor (Governor); and a Deputy. The King collects 800 tributes (equivalent to 3,200 subjects)." During this period, Vigan was composed of 19 barrios (districts). Between 1645 and 1660, Vigan was divided into 21 Cabezas de Barrio (Town Mayors) as mentioned in the Libro de Casamiento (Book of Marriage); from the records of the parish house of Vigan found in its archives. Separated from the indigenous population, the Chinese migrants were residents in a neighbourhood called El Pariancillo, los Sangleyes del parian (The Sangleyes of the Parian); and the Spanish settlers were residents in a town called Los Españoles de la Villa (The Town Spaniards). During the Philippine Revolution, revolutionary forces under Manuel Tinio, supported by the Ilocano rebels, attacked and defeated the Spanish colonial forces and captured the city in the Siege of Vigan.

At the start of World War II, Vigan was one of the first places in the Philippines invaded by Japan on December 10, 1941. In 1945, combined U.S. and Philippine Commonwealth ground troops, aided by Ilocano resistance fighters, defeated the Japanese Imperial forces and liberated Vigan. In 1999, Vigan was listed by UNESCO as the best preserved example of Spanish colonial towns in Asia.

Recent history Cityhood On December 27, 2000, then President Joseph Estrada signed Republic Act No. 8988, that "revalidated and recognized" Vigan's city status granted by virtue of the Royal Decree of September 7, 1757, issued by Ferdinand VI, King of Spain.
