The Pungyang Jo clan saw that Yi Myeongbok was only 12 years old and would not be able to rule in his own name until he came of age, and that they could easily influence Yi Ha-eung, who would be acting as regent for his son. As soon as news of Cheoljong's death reached Yi Ha-eung through his intricate network of spies in the palace, he and the Pungyang Jo clan took the hereditary royal seal (considered necessary for a legitimate reign to take place and aristocratic recognition to be received), effectively giving Queen Sinjeong absolute power to select the successor to the throne. By the time Cheoljong's death became a known fact, the Andong Kim clan was powerless to act according to law because the seal already lay in the hands of Grand Royal Dowager Queen Shinjeong.
