Philip II of Spain recognized the sovereign rights of the principalía, local Philippine nobles and chieftains who had converted to Catholicism.

Philip II, sometimes known in Spain as Philip the Prudent, was King of Spain from 1556, King of Portugal from 1580, and King of Naples and Sicily from 1554 until his death in 1598. He was also jure uxoris King of England and Ireland from his marriage to Queen Mary I in 1554 until her death in 1558. Further, he was Duke of Milan from 1540. From 1555, he was Lord of the Seventeen Provinces of the Netherlands.

The principalía or noble class was the ruling and usually educated upper class in the pueblos of Spanish Philippines, comprising the gobernadorcillo, tenientes de justicia, and the cabezas de barangay who governed the districts. Also included in this class were former gobernadorcillos or municipal captains, and municipal lieutenants in good standing during their term of office.
