King Narai of the Ayutthaya Kingdom, recognizing the political complexities and threats to his reign, appointed Phetracha as regent. This decision, made in a context of increasing foreign intervention and dissatisfaction among the nobility, catalyzed a series of political upheavals. Phetracha, originally a military commander, was seen by many as a figure capable of restoring stability while also expanding his power base. His nomination was met with mixed reactions, as factions within the court feared his growing influence and the potential for tyranny.

As tensions mounted, the dissatisfaction among the military and nobility grew. Phetracha, capitalizing on this unrest, quickly organized a revolt against King Narai's administration. Aligning with various disgruntled nobility and military leaders, he led an insurrection that effectively dismantled the existing power structure. The revolutionary fervor spread throughout the kingdom, ultimately leading to the overthrow of King Narai and Phetracha’s ascension as the new king.

Phetracha’s reign marked a significant shift in the Ayutthaya Kingdom’s governance and foreign relations. He was keen on reducing foreign influence, particularly that of the French, and sought to restore traditional Thai values. His rule following the revolution proved to be one of consolidation and review of foreign policies, shaping the future direction of the kingdom in a rapidly changing regional context.
