Mangaldan, officially the Municipality of Mangaldan (; ; ), is a 1st class municipality in the province of Pangasinan, Philippines. According to the 2020 census, it has a population of 113,185 people. History Mangaldan owns the distinction as the third town in Pangasinan to be founded by the Dominican missionaries. As early as 1591, Mangaldan already existed as a Spanish encomienda. Its foundation as a town is attributed to Blessed Juan Martinez de Santo Domingo, a former missionary of Pangasinan who died a martyr's death in Japan on 19 March 1618. Mangaldan started as a "visita" of Calasiao and it remained as such until the Dominicans created it as an independent vicariate under the patronage of St. Thomas Aquinas on 2 June 1600. It is said that of all the people of Pangasinan, the Mangaldanian were the most difficult to convert. The greatest enemy of the missionaries in the town was a certain man named Casipit who tried to force them out of the town and even attempted to kill some of them. Yet, when he was converted by the first apostle, Fr. Pedro Soto, he became the principal propagator of the Faith. He contributed a great sum of money for the construction of the first church. In the second half of the 19th century, Mangaldan was the richest town in the province. This was due to the famous irrigation system which the missionaries built within the confines of the town causing its fertile fields to yield bountiful harvest of palay. Most outstanding in this gigantic task was Fr. Jose Torres who gave his life to bring it to completion in 1892. The third church to be built in Mangaldan was completed in 1812 by Fr. Lorenzo Martin. It collapsed during the great earthquake of 16 March 1892, together with the big chapel in the cemetery. The construction of the convent dates back in 1747. The construction of the sixth and present church of Mangaldan was begun in 1942 by Fr. Juan Sison, and was completed 20 years later by Fr. Leon Bitanga. During World War II, Mangaldan had an airstrip that was used by the American military. Geography Mangaldan is located in the central part of Pangasinan.
