However, the reforms faced much opposition from conservative nobles who led the coup in 1506 that placed Jungjong in power. After four years of reformist agenda, Jungjong abruptly abandoned Jo Gwang-jo's programs because he either lost confidence in Jo's programs or feared that Jo was becoming too powerful. While Jungjong and Jo Gwang-jo shared the reformist agenda, Jungjong was also chiefly interested in solidifying royal authority whereas the latter was more concerned with neo-Confucian ideology, according to which those who rule must be a virtuous example to the rest. Finally in November 1519, when conservative officials slandered Jo Gwang-jo to be disloyal by writing "Jo will become the king" () with honey on leaves so that caterpillars left behind the same phrase as if in supernatural manifestation, Jungjong executed Jo Gwang-jo on charge of factionalism and exiled many of his followers, abruptly abandoning his reforms. This incident is known as the Third Literati Purge of 1519 or Gimyo massacre of scholars.
