in the north to Namacpacan in the south were part of a region called the Ylokos. It lies between the West Philippine Sea in the west and the
Northern Cordilleras in the east. On the western side, the land is sandy; while on the eastern side (near the mountains that separate the region from the
Mountain Province) the land is rocky. This left a narrow strip of plains for cultivation. The mountains come so close to the sea that the highway is carved into them. The pressure of an increasing population and the need for land made the people thrifty, and they built their villages near small bays and coves called ''looc'' in the local dialect. These coastal inhabitants were known as ''Ylocos'', which means "from the lowlands". The region was then called by the ancient name Samtoy, from ''sao mi ditoy'' ("our language" in
Ilocano).
Spanish colonial era
The Ilocos region was a thriving and fairly advanced cluster of towns and settlements familiar to Chinese, Japanese, and Malay traders when the Spanish explorer
Juan de Salcedo arrived in

on June 13, 1572. The Spanish made Cabigbigaan their headquarters, which Salcedo called Villa Fernandina. It also became known as the ''Intramuros de Ilocandia''. Salcedo declared all of Northern Luzón an ''

'' (land grant). He was the ''encomendero'' of Vigan and lieutenant governor of Ylokos until his death in July 1574.
Augustinian missionaries evangelized the region, establishing parishes and building churches that still stand. Three centuries later, Vigan became the seat of the
Archdiocese of Nueva Segovia.
The coast of Samtoy was known to the Spanish colonizers in 1572, when Juan de Salcedo traveled along it. Sent by
Miguel López de Legazpi
Miguel López de Legazpi (12 June 1502 – 20 August 1572), also known as ''Adelantado, El Adelantado'' and ''El Viejo'' (The Elder), was a Spanish conquistador who financed and led an expedition to conquer the Philippines, Philippine islan ...
to explore the island of Luzón, Salcedo founded ''Ciudad Fernandina'' in 1574 in Bigan, in present-day Ilocos Sur. It became the center of Spanish rule and influence, including the evangelization and pacification movements. Due to Salcedo's efforts, the settlements in Tagurín, Santa Lucía, Nalbacán, Bantay, Candón and Sinayt were pacified and paid tribute to the King of Spain.
Conversions
According to the Spanish chronicler Pigafetta, "The Ilocos are all Christians and are the humblest and most tractable". The Augustinians established parishes in Santa in 1576, Tagurín in 1586, Santa Lucía in 1586, Nalbacán in 1587, Candón in 1591, and Bantay in 1590. They built a church in Bigan in 1641 which later became the Cathedral of the Episcopal See of Nueva Segovia after 117 years.
Partition of Ylokos
Ylokos consisted of the present-day provinces of
Ilocos Norte, Ilocos Sur,
Abra and part of
Mountain Province. A royal decree of February 2, 1818 separated Ilocos Norte from Ilocos Sur, the latter including northern La Union (as far as Namacpacan, present-day Luna) and present-day Abra.
The sub-provinces of Lepanto and Amburayan in Mountain Province were annexed by Ilocos Sur.
The passage of Act No. 2683 by the
Philippine Legislature in March 1917 defined the province's current geographical boundaries.

Juan de Salcedo as the capital of Ylocos. The town, with a population of 8,000 (greater than that of Manila at the time), was the center of Ilocano civilization before Salcedo's arrival. It was somewhat prosperous, trading with the Chinese and Japanese who brought jars, silk and crockery through the nearby port of Pandan,
Caoayan.
In the 19th century, Vigan traded with Europe. Ships loaded with indigo delivered their goods to textile mills. The invention of chemical dyes in Germany eliminated this industry. Affluent citizens of Vigan stocked their homes with statuettes of brass and iron, dinnerware, and other artifacts of European civilization, including fine ivory, inlaid furniture, and Chinese wares.
Social institutions
Salcedo bequeathed his ''encomienda'' to a select group who continued the tenancy system which developed into the practice of
caciquism,
landlordism and
usury
Usury () is the practice of making loans that are seen as unfairly enriching the lender. The term may be used in a moral sense—condemning taking advantage of others' misfortunes—or in a legal sense, where an interest rate is charged in e ...
. The ''kaillanes'' revolted against the aristocracy in 1762. Vigan's two sections during the mid-19th-century indigo boom—one for the ''meztizo''s and the other for the ''naturales''—remain distinct.
Migration
Spanish colonizers used free labor in the development of Ilocos Sur. Resentment of free labor triggered sporadic revolts, and those who refused to be slaves or tenants left the region for
Abra and the
Cagayan Valley. From 1898 to the first decade of the 20th century, covered oxcarts moved to the rich plains of

Economic prosperity
The first half of the 19th century was an economic boom for Ilocos Sur. During this period, the cotton, tobacco and indigo industries were encouraged by the government. With the operations of the
Royal Company of the Philippines (), the textile industry was developed on a large scale and the abolition of the tobacco monopoly accelerated economic progress.
Revolts
The beginning of Spanish rule to the first decade of the nineteenth century was characterized by revolts against tribute, forced labor and monopolies. The Ilocos revolt (1762–1763), better known as Silang's Revolt, was aimed at the ''babaknangs'' and the ''alcalde-mayor'' of Vigan. After
Diego Silang's assassination on May 28, 1763, his wife
Maria Josefa Gabriela continued the fight until she was captured and hanged on September 20, 1763. A revolt against the government monopoly of ''basi'', the native wine, began on September 16, 1807. Regular troops and recruits defeated the rebels.
On March 25, 1898, Isabelo Abaya began an uprising in Candón and raised a red flag in the town plaza as a response to Spanish abuses and oppression. A revolutionary government was established, and several other revolts followed. The Spanish sent shock troops to re-occupy Candon, and most of the leaders and participants in the uprising who surrendered were arrested and executed.

Marcos era
Much of the history of Ilocos Sur during the 21 years of the
Marcos dictatorship are not well-documented, with the most prominent portrayals of Ilocos Sur history preferring to skip from the years immediately after Philippine independence in the 1940s, jumping straight to contemporary times.
In Ilocos Sur, the most prominent protests and incidents of the Marcos era – such as the infamous "Bantay incident: and the assassination of Reoresentative Floro Crisologo - actually took place before the declaration of martial law in 1972, and involved the Marcos administration's support for local strongmen
[McCoy, A. “Global Populism: A Lineage of Filipino Strongmen from Quezon to Marcos and Duterte,” in Kasarinlan (Quezon City) 32, Issue nos. 1–2, 2017.] rather than national controversies.
Organizations such as the Federation of Free Farmers (FFF) and Federation of Free Workers (FFW), sometimes supported by progressive elements of the Catholic Church, continued to fight for the labor rights of the poor until the 1972 declaration of Martial law made it illegal to peaceful protests.
Some of the frustrated protesters then opted to pursue an armed resistance against the dictatorship,
many of whom only returned to peaceful life after the Marcoses were finally deposed by the civilian-led
People Power revolution of 1986.
[Davis, Leonard. Revolutionary Struggle in the Philippines. London: Palgrave Macmillan, 1989]
There were numerous
human rights violations documented in Ilocos Sur in connection to the
Marcos martial law era,
[McCoy, A. “Dark Legacy: Human Rights Under the Marcos Regime” in Memory, Truth Telling, and the Pursuit of Justice: A Conference on the Legacies of the Marcos Dictatorship. Quezon City: Ateneo De Manila University Press, 2001.] and there was at least one camp in the province that held political Prisoners during the Marcos era - a "Camp Diego Silang",
which is different from the Police Camp established in La Union in 1989.
Bantay incident
Marcos' victory in the 1965 Presidential Elections had required that he gain political control of the north as a solid voting block, which meant forming alliances with the most prominent local "warlords" of the time
[ - Ilocos Norte 1st District Representative Antonio Raquiza whom Marcos would later appoint as Secretary of Public Works and Highways;][ La Union 2nd District Representative Manuel T. Cases;][ and Ilocos Sur 1st District Representative Floro Singson Crisologo.] Crisologo's cousin, Captain Fabian Ver of the Philippine Constabulary's Criminal Investigation Service, became part of Marcos' inner circle and eventually became one of Marcos' most trusted lieutenants. Historian Alfred McCoy noted in a 2017 article that "The Crisologos were one of the political families that was buoyed by the rise of Marcos to power, and that they were able to dominate their political rivals in Ilocos Sur as Marcos solidified his hold on power. McCoy also noted that Crisologo created a private army, which residents called the ''saka-saka'', which literally means "barefooted" in Ilocano; controlled electoral offices; and used blockades to create a monopoly on the tobacco that came out of the province.
But a turning point took place in May 1970 with the so-called "Bantay Incident". The ''saka-saka'' assassinated a former mayor of Bantay, the town next to Vigan, in 1969, and then in May 1970, burned the villages of Ora Este and Ora Centro in retaliation for their residents' support for Crisologo's opponent Chavit Singson during the 1996 elections. One elderly woman who was killed in the blaze. Public opinion compelled Marcos to investigate the incident and arrest Crisologo's son Vincent
Vincent (Latin: ''Vincentius'') is a masculine given name originating from the Roman name ''Vincentius'', which itself comes from the Latin verb ''vincere'', meaning "to conquer."

, who was reported to be the leader the ''saka-saka'' at the time. McCoy notes that Crisologo reportedly went to Marcos and appealed for help, while demanding a greater share of rewards that Marcos had promised him in exchange for supporting his presidential reelection campaign in 1969. When Marcos refused, Crisologo reportedly then threatened to expose Marcos's and Ver's participation in cornering the tobacco monopoly in the Ilocos Region

Crisologo's murder and the defeat of his wife Carmeling to Chavit Singson in the gubernatorial race and that of his son Vincent in the mayoralty contest in Vigan to a brother of Chavit in 1971 led to the end of his family's political dominance in the province and the rise of the Singson family to prominence.

Inhabitants
Ilocos Sur is inhabited mostly by Ilocanos belonging to the third largest ethnic group of Austronesian origin. A Spanish chronicler wrote that "the people are very simple, domestic and peaceful, large of body and very strong. "They are highly civilized. They are a most clean race, especially the women in their homes which they keep very neat and clean."
Miguel de Loarca records around 1582 that the Ilocanos are intelligent as the Zambaleños for they are farmers. The main occupation of the people is agriculture.
Father Juan de Medina noted in 1630 that the natives are 'the humblest and most tractable known and lived in nest and large settlements'.

Agriculture
Ilocos Sur's economy is agrarian, but its of unfertile land is not enough to support a population of 338,579.
Agricultural crops such as rice, corn tobacco and fruit trees dominate their farm industries. Secondary crops are camote and cassava, sugar cane and onions.
The rapidly growing population, the decreasing fertility of the soil, and the long period between the planting and harvesting season, have forced the people to turn to manufacture and trade. Many Ilocanos go to the Cagayán valley, Central Plains and Mindanao to sell Ilocano woven cloth.
Virginia leaf tobacco is still a premier cash crop, after a windfall brought about by the Tobacco Subsidy Law authored by Congressman Floro Crisologo in 1964, and later enhanced by the Republic Act No. 7171 authored by Congressman Luis "Chavit" Singson.
Weaving is the most extensive handicraft, once bolstered by the installation of the NDC Textile Mills in Narvacan which supplied the weavers with yarn.
