Four pillars (Vietnamese bureaucrats)

The "Four Pillars" (Vietnamese: Tứ trụ) refers to a high-ranking group of officials during certain periods of Vietnamese dynastic history, primarily during the Nguyễn dynasty (1802-1945). This council consisted of four of the most powerful mandarins in the imperial court, holding significant influence over policy and governance. These individuals typically occupied positions such as Grand Tutor to the Crown Prince, Grand Protector of the Heir Apparent, or held key ministries.

The composition and specific titles of the "Four Pillars" could vary depending on the reigning emperor and the prevailing political climate. The system aimed to provide checks and balances on power, although in practice, rivalries and factionalism among the "Four Pillars" could and often did occur. Their influence stemmed from their close proximity to the emperor and their control over important bureaucratic functions. The "Four Pillars" played a critical role in advising the emperor on matters of state, overseeing the implementation of policies, and managing the day-to-day affairs of the court. They were expected to be men of high intellect, moral character, and extensive experience in government. The existence of the "Four Pillars" system reflects the Confucian ideals of governance that heavily influenced the Vietnamese court. Their actions, both individually and collectively, had a profound impact on the course of Vietnamese history.
