However, the queen consort had begun to secretly form a powerful faction against the Heungseon Daewongun, once she reached adulthood; now, with the backing of high officials, scholars, and members of her clan, she sought to remove the Heungseon Daewongun from power. Min Seung-ho, the queen consort's adoptive older brother, along with court scholar Choe Ik-hyeon, devised a formal impeachment of the Heungseon Daewongun to be presented to the Royal Council of Administration, arguing that Gojong, now 22, should rule in his own right. In 1873, with the approval of Gojong and the Royal Council, the Heungseon Daewongun was forced to retire to Unhyeongung, his estate at Yangju. The queen consort then banished the royal concubine along with her child to a village outside the capital, stripped of royal titles. The child died on 12 January 1880.
