Injo Restoration
The Westerner faction deposed Gwanghaegun and enthroned Prince Neungyang as King Injo; the new pro-Ming stance soured relations with the Later Jin.

Gwanghaegun governed with the Northerner faction and steered a neutral course between the Ming and the Later Jin. But killing his half-brother Prince Yeongchang and confining Queen Dowager Inmok in the western palace, along with a diplomacy that seemed to betray the Ming, gave the Westerners their justification for a coup.
On the night of the 13th day of the 3rd month, 1623, Westerners such as Kim Ryu, Yi Gwi and Choe Myeong-gil, with Prince Neungyang and troops under Yi Gwal and others, passed through Changuimun Gate and entered Changdeokgung. Neungyang took the throne by the queen dowager’s order; Gwanghaegun was exiled to Ganghwa and later to Jeju, and Northerner leaders such as Yi I-cheom and Jeong In-hong were executed.
The Westerners now led the government, sharing some posts with the Southerners. The new pro-Ming, anti-Jurchen policy invited the 1627 invasion, and Yi Gwal, unhappy with his reward, rebelled the following year (1624).
