The young king was very ambitious, and tried to reform the government of the time that was rife with corruption, a legacy of the failed reforms during his father's reign. He rehabilitated Jo Gwang-jo and recruited Sarim scholars who turned away from politics after Third Literati Purge of 1519. His maternal uncle Yun Im exercised great power during this period. However, Injong was too often ill and died in 1545, just one year after coming to the throne. Following his death, Yun Im was executed by Yun Won-Hyung in the Fourth Purge of 1545 when King Myeongjong (son of the ambitious Queen Munjeong) succeeded the throne.
