Seonjo of Joseon

Seonjo was the 14th monarch of the Joseon kingdom in Korea.

He was born Yi Yeon in 1552 in Hanseong, which is now Seoul. His biological father was Prince Deokheung. His grandfather was King Jungjong. Seonjo was eventually adopted by Queen Insun. When King Myeongjong died without an heir, Seonjo became the next in line. He was crowned king in 1567 at the age of 16. His reign would eventually be marked by both reform and intense conflict.

At the beginning of his rule, Seonjo focused on rebuilding the nation. He wanted to fix political corruption from previous eras. He supported the Sarim scholars, who were often persecuted by the aristocracy. These scholars followed Confucianism, a system of ethics and philosophy. Seonjo appointed famous scholars like Yi Hwang and Yi I to government offices. He also reformed the civil service examination system. Previously, these exams focused mostly on literature. Seonjo changed the rules to make history and politics more important. These actions earned him respect and brought a short period of peace.

However, political unity did not last long. The government eventually split into two major factions. These groups were known as the Westerners and the Easterners.

The Westerners were led by Shim Eui-gyeom, who was a conservative relative of the queen. The Easterners were led by Kim Hyowon, who pushed for liberal reforms. The two groups even lived in different parts of the city. The Easterners later split further into Northern and Southern factions. This intense factionalism lasted for 200 years. It eventually contributed to the collapse of the state.

These political divisions made the country vulnerable to invasion. In 1592, Hideyoshi unified Japan and sought to conquer Asia. He asked to march through Korea to reach China. Seonjo refused this request and alerted China to the danger. However, the two political factions could not agree on the threat.

One delegate warned of a massive troop buildup. Another delegate argued the forces were only for internal Japanese control. Because the Easterners held more power, the king ignored the warning. The military remained unprepared for the coming conflict.

In April 1592, the Imjin War began with a massive Japanese invasion.

Roughly 18,700 troops under Konishi Yukinaga landed at Busan. Other large forces under Katō Kiyomasa and Kuroda Nagamasa also invaded. The Japanese forces marched toward the capital, Hanyang. Many Korean cities and forts were burned during the advance. As the Japanese encroached, Seonjo moved north to Pyongyang and then to Uiju. During this time, many public buildings, including Gyeongbokgung, were destroyed by people who had lost hope.

Seonjo made several significant decisions during the war. He wrote the first public government documents in Hangul. Hangul is the Korean phonetic alphabet. He chose this instead of Hanja, the complex Chinese characters. This ensured commoners could read the messages. He also issued an edict promising government titles to anyone who helped fight. This included people who captured invaders or rescued prisoners. This policy applied regardless of a person's social class.

While the land suffered, the navy under Admiral Yi Sun-sin provided crucial defense. He defeated Japanese fleets and blocked their supply ships.

After the death of Hideyoshi in 1598, the Japanese withdrew from Korea. The war had left the land devastated and the people starving. Seonjo attempted to rebuild the nation through new laws. He established army training facilities and reformed taxation. Under his new system, people could gain higher social status or legal exemptions by paying taxes in rice.

Despite these efforts, political fighting and famine slowed the recovery. Successors also faced tension regarding the royal lineage. Seonjo died in 1608, leaving a kingdom in the midst of a difficult reconstruction.
