In the beginning, Sampaloc was a barrio of Lucban called Dingin, consisting of three (3) sitios. It was named after a big tamarind tree found in the center of the settlement. Later the name was changed to Alfonso Trece in honor of the then King of Spain. Through the efforts of Juan Pineda who became “absolute’ in 1892, Sampaloc became a municipality. A year later, the first election was held, the electors being the parish priest, the Tenyente Mayores, the ex-cabezas and prominent citizens of the town. Juan Pineda was elected the first Captain or the town’s head. Diego Gagan succeeded Juan Pineda as Capitan. When the impact of the Philippine-American War reached the town, Capitan Diego Gagan was forced to leave, and Juan Saludades, then Leader of the local insurrectos, took over.
Juan de Asis became president in 1904. Some improvements were made: a new church, later destroyed by a storm in 1934, was constructed. After Jose de Asis, Capitan Diego came to power again as president, followed by Mateo Almozara, Mateo Apordo, Sisenando Pineda and Andres Jardin.
