son of Seonjo, and Grand Prince Yeongchang (永昌大君, 영창대군), the queen's son. It was not Gwanghaegun's plan to keep his throne; and in fact, he actually tried to bring minor factions into the government, but was blocked by opposition from members of the Greater Northerners, such as Jeong In-hong and Yi I-cheom. The actions made Gwanghaegun even more unpopular among wealthy aristocrats, and they finally began plotting against him. In 1623, members of the ultra-conservative Westerners faction, Kim Ja-jeom, Kim Ryu, Yi Gwi and Yi Gwal, launched a coup that resulted in the dethroning of Gwanghaegun, who was sent into exile on Jeju Island. Jeong In-hong and Yi Yicheom were killed, and followed suddenly by the Westerners replacing the Greater Northerners as the ruling political faction. The Westerners brought Injo to the palace and crowned him as the new King of Joseon. Although Injo was king, he did not have any authority since almost all of the power was held by the Western faction that dethroned Gwanghaegun. Yi Gwal's Rebellion Yi Gwal thought he was mistreated and received too small a reward for his role in the coup. In 1624, he rebelled against Injo after being sent to the Northern front as military commander of Pyongyang to fight against the expanding Manchus, while other significant leaders of the coup were rewarded with positions in the King's court. Yi Gwal led 12,000 troops, including 100 Japanese (who defected to Joseon during Japanese invasions of Korea), to the capital, Hanseong, where Yi Gwal defeated a regular army under the command of General Jang Man (张晚) and surrounded Hanseong in what is known as the Battle of Jeotan. Injo fled to Gongju, and Hanseong fell into the hands of the rebels. On February 11, 1624, Yi Gwal enthroned Prince Heungan (興安君, 흥안군) as the new King. However, General Jang Man soon returned with another regiment and defeated Yi Gwal's forces. The Korean army recaptured the capital soon after, and Yi Gwal was murdered by his bodyguard, resulting in the rebellion's end. Even though Injo was able to keep his throne, the uprising displayed the weaknesses of royal authority while asserting the superiority of the aristocrats, who had gained even more power by fighting against the rebellion. The economy, which was experiencing a slight recovery from Gwanghaegun's reconstruction, was again ruined, and Korea would remain in a poor economic state for a few centuries.
