Like many other municipalities established during Spanish era, Zarraga had undergone the days of trial and humiliation. In the early part of 1904, it became the arrabal of the municipality of Sta. Barbara, much to the chagrin of its people. It remained as such up to the year 1940. When by virtue of Executive Order No. 295, by them President Manuel L. Quezon, it again became a municipality. Emelio Gregorius became its first municipal mayor. Mayor Porferio Pinuela was the first elected mayor, followed by Jovito Arimas. Following the death of Arimas, his vice-mayor, Emiliano Lacson succeeded him as municipal mayor.  

During the next election, Mayor Silveo Jr. was elected mayor and remained as such until the EDSA revolution in 1986 when he had to relinquish his post following the orders of the Aquino administration. Mayor Orlando replaced him. In the 1995 elections, Mayor Silveo was elected mayor and remains as such to the present.
