Trần Thánh Tông, having ascended to the throne in 1258 and ruling effectively over the Trần dynasty, recognized the importance of a smooth succession for the prosperity of the realm. After more than two decades of stable governance, he decided that the time had come to pass the throne to Trần Khâm, his chosen crown prince. This move was characterized by the thoughtful consideration of both national security and political stability, ensuring that the power transition would be seamless in the face of challenges from external and internal factions. The court witnessed a grand ceremony where Trần Khâm was officially proclaimed as the new emperor, marking the end of Trần Thánh Tông's direct rule, but not his influence on the upcoming reign. The transfer of power emphasized the necessity of preparing the next generation for leadership roles in governing the nation. Following the ceremony, Trần Thánh Tông adopted the title of Retired Emperor, which allowed him a ceremonial, advisory role while preserving the integrity of the new emperor's authority. This approach was a strategic maneuver to maintain the strength of the Trần dynasty against regional challenges and internal power struggles. It symbolized stability and continuity within the leadership structure while ensuring that Trần Khâm could benefit from his father's wisdom and experience. Such careful planning caught the attention of neighboring kingdoms and affirmed the Trần dynasty’s commitment to strong governance.
