Palaris

Pantaleon was born to Tomas Perez, a village chief, and Catalina Ugnay, both of the town of Binalatongan (now San Carlos City), Pangasinan.

Being a family of a village chief (or cabeza de barangay, in Spanish), the Perez clan were members of Binalatongan's principalia (ruling class).

He then moved to Manila and worked as the coachman of the Spanish official Francisco Enríquez de Villacorta, a member of the Audiencia Real, which served as the privy council of the governor-general who governed the Philippines.

After the British Invasion of the Philippines during the Seven Years' War, the Spanish colonial government, including Villacorta, had relocated to Bacolor in the province of Pampanga, which was then adjacent to Pangasinan.

Pangasinenses took over all official functions and controlled the province up to the Agno River, the natural boundary between Pangasinan and neighboring Pampanga in the south.

The Spanish friars, who were allowed to stay in the province, also started a campaign to persuade Pangasinan residents of the futility of the Palaris Revolt.

By September 1763, news of the peace treaty reached Pangasinan and army of Palaris' men surrendered and returned to normal life amid the Spanish offensive.

But his presence terrified his protectors and his own sister Simeona, who was apparently threatened by the Spanish clergy, betrayed him to Agustín Matias, the gobernadorcillo (mayor) of the razed Binalatongan.
