The Inner Court gained power over the formal Outer Court—the official civil service—by leveraging direct access to the emperor to circumvent established administrative protocols.12

This secondary seat of power originated from the secretariat, which began as a subordinate agency within the Privy Treasury. As secretariat officials—often including eunuchs and the emperor's favorites—grew in influence, they utilized their proximity to the throne to bypass the formal, rigid procedures required of senior ministers like the chancellor.132

The shift in power was solidified when these individuals were granted privileged, honorary titles, such as "supreme commander." When this title was paired with the authority to lead the secretariat, the incumbent could effectively control state decisions, often overshadowing the highest-ranking officials of the Outer Court. This mechanism allowed figures such as Wang Mang to assert significant political control without the checks and balances intended by the traditional government structure.13
