Biography

Political factions

There were two political factions at the time Myeongjong came to power; Greater Yun, headed by Yun Im, Injong's maternal uncle, and Lesser Yun, headed by Myeongjong's maternal uncles, Yun Wŏnhyŏng and Yun Wollo. (Yun Im and Yun Brothers were close relatives by that period's standards - Yun Im was a third cousin once removed of Yun Brothers.) Greater Yun took power in 1544, when Injong succeeded Jungjong; but they failed to wipe out their opposition, since Queen Munjeong protected the Lesser Yun faction and other opposition officials.

After the death of Injong in 1545, Lesser Yun replaced Greater Yun as the majority in the royal court and brutally ousted their adversaries in the Fourth Literati Purge of 1545. Yun Im was executed, as were many of his followers.

Rise of Yun Wŏnhyŏng

The Lesser Yun faction continued to attack their opposition. In 1546, Yun Wŏnhyŏng impeached his older brother, Yun Wollo, who was executed a few days later along with his followers. Facing no opposition from the government, Yun Wŏnhyŏng became Minister of Personnel 이조판서 in 1548, Left State Councilor in 1551 and ultimately Chief State Councilor 영의정 in 1563.

Despite Yun Wŏnhyŏng's violent rule, Queen Munjeong was an effective administrator, distributing to the common people land formerly owned by the nobility. However, she held on to rule even after the king reached his majority at the age of 20.

Death of Queen Munjeong

After the death of Queen Munjeong in 1565, the king decided to rule the kingdom by himself and had his uncle, Yun Wŏnhyŏng, put to death, along with his second wife^[2] Jeong Nan-jeong, who also rose to power due to her close friendship and being the second sister-in-law to Queen Munjeong. Yun Wŏnhyŏng allowed corruption to flourish in the government. And while the kingdom was unstable, Jurchens, Japanese, and rebellious troops rampaged at will and threatened the government itself. Rebel leader Im Kkeok-jeong was arrested and executed in 1552, but outside invasion continued; the Joseon Dynasty had to re-mobilize its army and navy along to protect its borders.

Death and succession

Myeongjong tried to reform the government after taking power into his own hands by recalling and reinstating Sarim scholars who were exiled in the purge, but died only two years later without any male issue. Yi Gyun, Prince Haseong (later known as Yi Yeon, Seonjo of Joseon), his half-nephew from his older half-brother Grand Internal Prince Deokheung, was adopted by his wife, the now Queen Dowager Uiseong, to succeed the throne in 1567.
