With the fall of the Spanish regime during the Philippine Revolution in 1898, a short-lived provincial government was set up under the revolutionary regime. This was soon displaced by an American military established in April 26, 1901 then civil government. At this time, Albay included the formerly independent island-province of Catanduanes as a municipality. In 1905, Catanduanes was made a sub-province of Albay, and in 1945, it was separated and organized again into a separate province. Albay was created as a province under Act 2711 on March 10, 1917, which comprised the following municipalities; Bacacay, Camalig, Daraga, Guinobatan, Jovellar, Legazpi, Libong (Sto. Domingo), Libon, Ligao, Malilipot, Malinao, Manito, Oas, Polangui, Rapu-Rapu, Tabaco and Tiwi. Legazpi was the former town of Albay, which had been renamed Legazpi in 1836, changed to Albay again in 1908, and finally back to Legazpi when it became a chartered city in 1948. In 1963 the additional municipality of Pioduran was created.
