During the early Spanish Era, the municipality of Marabut was a mere sitio of Basey, which evolved into a barrio. In 1949, Ysidro M. Ferreras who was then the Mayor of Basey submitted to President Elpidio Quirino a proposal to convert Barrio Sto. Niño into a separate municipality. Thus on July 22, 1949, Executive Order No. 247 was signed creating the Municipality of Marabut, named in honor of Congressman Serafin Marabut who was a native of Basey. Ysidro Ferreras was elected as the first municipal mayor.
