Seonjo of Joseon

Seonjo (Korean: 선조; Hanja: 宣祖; 6 December 1552 – 6 March 1608), personal name Yi Yeon (이연; 李昖), was the 14th monarch of the Joseon dynasty of Korea. He was known for promoting Confucianism and attempting reforms at the beginning of his reign. However, he later gained infamy from the political discord and his incompetent leadership during the Japanese invasions of Korea.

King Seonjo was born Yi Yeon in 1552 in Hanseong (today, Seoul), capital of Korea, as the third son of Prince Deokheung (덕흥군), himself son of King Jungjong and Royal Noble Consort Chang of the Ansan An clan (창빈 안씨).

He was given the title of Prince Haseong, and was eventually adopted by Queen Insun. When King Myeongjong died young without an heir, Prince Haseong was the next in the line of succession. Then, by decision of the royal court, he was crowned king in 1567 at the age of 16. His father had the status of Grand Internal Prince (대원군, Daewongun, 'Great Prince of the Court).

According to imperial sources, King Seonjo focused on the improvement of the lives of the common people, as well as rebuilding the nation after the political corruption during the chaotic reign of Yeonsangun and King Jungjong. He encouraged Sarim scholars, who had been persecuted by entrenched aristocrats in four different purges between 1498 and 1545 during reign of Yeonsangun and Jungjong. Seonjo continued the political reforms of King Myeongjong, and put many famous Confucian scholars, including Yi Hwang, Yi I, Chŏng Ch'ŏl, and Yu Sŏngnyong, in office.

Seonjo also reformed the civil service examination system, particularly the civil official qualification exam. The previous exam was mainly concerned with literature, not with politics or history. The king himself ordered the system to be reformed by increasing the importance of these other subjects. He also restored the reputations of executed scholars such as Cho Kwangjo, who died in Third Literati Purge of 1519, and denounced the accomplishments of corrupt aristocrats, notably Nam Kon, who instigated the purge under Jungjong and contributed greatly to the corruption of the era. These acts earned the king the respect of the general populace, and the country enjoyed a brief era of peace.

Among the scholars King Seonjo called to the government were Sim Ŭigyŏm and Kim Hyowŏn. Sim was a relative of the queen and heavily conservative. Kim was the leading figure of the new generation of officials and called for liberal reforms. The scholars who supported King Seonjo began to split into two factions, headed by Sim and Kim. Members of the two factions even lived in the same neighborhood; Sim's faction lived on west side of the city while Kim's followers gathered on the east side. Consequently, the two factions began to be called the Westerners and the Easterners ; this two-faction based political system lasted 200 years and later helped bring about the collapse of the Joseon dynasty.

At first the Westerners earned the favor of the king, since Sim was related to the queen and also had larger support from wealthy nobles. However, their attitudes on reformation and Sim's indecisiveness helped the Easterners take power, and the Westerners fell out of favor. Reforms were accelerated during the first period of influence of the Easterners, but then many Easterners began to urge others to slow down the reforms. The Easterners were once again divided into the Northern and the Southern Faction. Yu Sŏngnyong led the Southern faction while the Northerners divided even further after arguments over many issues; the greater Northern faction came to become extremely liberal in the scope of their reform goals, while the "lesser" Northern faction was less reformist but still more open to reform than the Southerners.

The political divisions caused the nation to be weakened, since the size of the military was also one of the issues on the reform agenda. Yi I, a neutral conservative, urged the king to increase the size of the army to prepare against future invasions from the Jurchens and Japanese. However, both factions rejected Yi's suggestions, and the size of the army was decreased further since many believed the peaceful period would last. The Jurchens and Japanese used this opportunity to expand their influence in East Asia, resulting in the Seven-Year War, and the foundation of the Qing dynasty in China, both of which would lead to devastation on the Korean Peninsula.
