Precolonial period Caboloan's capital, Binalatongan (modern-day San Carlos), located near the Agno River delta, was said to be the largest settlement in the entire region, with over two thousand houses. However, historian Erwin Fernandez (2010) notes that:Pangasinan history writers had propagated the names Kasilag and Kasikis as the two kings ruling in the coastal and interior communities contemporaneous with Rajahs Soliman and Lakandula but this contact period account did not cite any of these names. The reason might have been the 1920 source, on which these authors had relied, which mentioned Kasikis – the Census of the Philippine Islands…in the year 1918. Without going to the original sources, historical writers with the exception of historians are liable to writing fiction, not history. This situation similarly applies to the search for the founding date of Pangasinan. Kasikis and Kasilag might be another Urduja or Thalamasin.
Spanish conquest and occupation After the conquest of Pangasinan by
Juan de Salcedo in 1572, the encomienda of Pangasinan was founded as an
encomienda. However this did not yet include Caboloan. In 1574, the Chinese pirate
Limahong landed in Pangasinan to establish his own kingdom. In reaction, the Spaniards landed at
San Fabian on 23 March 1575. Afterwards, it was said that the Spaniards climbed at the foot of the
Zambales Mountains to observe the kingdom of Ari Kasikis, where they witnessed a highly organized
animistic ritual. In 1587, Binalatongan was founded by Spanish Dominicans as well as Augustinian missionaries such as Fr. Francisco dela Rama who evangelized the natives and established a church known as the Saint Dominic Church. It was reported to be the first town founded by the Dominicans in the Philippines. The mission of Binalatongan was officially accepted as a vicariate of the
Dominican Order in its First Provincial Chapter in 1588, with Fr. Bernardo de Santa Catalina, OP, as its first Vicar (equivalent to the office of the parish priest), together with Fr. Juan de Castro, OP, Fr. Marcos de San Antonio, and Bro. Juan Deza, OP as his assistants. At the start of the foundation, Binalatongan formerly included the towns of
Calasiao,
Binmaley,
Bayambang,
Malasiqui,
Aguilar,
San Carlos City,
Urbiztondo, and
Basista. In a letter of Fr. Diego de Rojas to the colonial governor in 29 March 1591, that the people of Caboloan preferred to dwell into the interior rather than settle at the royal encomiendas at the coasts, which were sandy and not suitable for their lifestyle. In a 1591 report about the various encomiendas of the archipelago, it was reported that Binalatongan had a population of around 3,200 people in total. In 1611, the province of Pangasinan was made, annexing both the settlements around the Lingayen Gulf excluding Bolinao, as well as the interior settlements, which included Binalatongan, ending its independence as a politically separate territory from Pangasinan. During the mid Spanish period, Binalatongan was well known as a site of many rebellions within Pangasinan, which included the revolts of
Don Andres Malong (1660) and
Juan de la Cruz Palaris (1762) during the
Seven Years’ War. On 4 November 1718, in the aftermath of the rebellious period, the capital of Binalatongan would be transferred in what is now known as the poblacion of San Carlos, in which the town would also be renamed the same date. == Culture and Religion ==
