Filipino traders settled in Malolos starting in 1670 for economic opportunity. The settlers increased, and Malolos began engaging with textile, rice production. However, the Chinese are expelled from the town on June 30, 1755, due to political and social issues. On August 31, 1859, Malolos was divided into three independent towns; "Malolos", "Barasoain, and "Santa Isabel". These new towns are former districts of Malolos, with own respective Presidente Municipal and Parish priests. With the beginning of American rule in 1903, these towns were again reunited into a single municipality. The two other districts became barangays under the political jurisdiction of Malolos. A major factor in the progress of Malolos was the opening of the Manila–Dagupan railways in April 1892. Malolos was first organized into a formal municipal unit in 1822 when the first "alcalde constitucional" or municipal head was appointed. He was Jorge de Victoria, a Filipino, who like all succeeding "alcaldes", served for one year. He was followed by thirty-one other "alcaldes", with Juan Dimagiba as the thirty-first. In 1859, Malolos was subdivided into three administrative districts; Malolos, Barasoain and Santa Isabel. Juan Dimagiba became the first "alcalde" of the down-scaled Malolos. There were 12 others who served as "alcaldes" from 1859 to 1879, the first one being Mariano C. Cristobal and the second being Capitan Tomas Tanchanco, whose term marked the start of civil turmoil in the town.

Malolos served as the capital of the short-lived republic from 1898 to 1899. In 1899, after the Malolos Constitution was ratified, the Universidad Scientifico Literaria de Filipinas was established in Malolos, Bulacan. It offered Law as well as Medicine, Surgery and Notary Public; Academia Militar,(the Philippine's First Military School) which was established on October 25, 1898; and The Burgos Institute, (the Philippine's first law school) and an exclusive school for boys. The Congress of the Revolutionary Government of the Philippines convened in Barasoain Church in Malolos on September 15, 1898. On the 18th, Aguinaldo proclaimed Malolos as the capital of the Philippines. The first important act of the Congress was the ratification on September 29, 1898, of the independence proclamation at Kawit, Cavite of June 12, 1898. On October 19, 1898, by virtue of an act of Congress,
