Laoac is the province's youngest municipality. Since the early 1900s, unsuccessful attempts to convert Laoac - then the biggest
barrio in
Manaoag - into a separate municipality were made until the revival of such movement by Westrimundo Tabayoyong. The implementation, however, was delayed by
the declaration of nationwide martial law later that year. the first municipal officials were elected, with Tabayoyong as mayor, and assumed office on March 5, 1980, formally inaugurating the corporate existence of the municipality. Tabayoyong served until his assassination at the municipal plaza on September 6, 1985. ==Geography==
