Imo Incident
Old-style soldiers angry over unpaid wages rose up and attacked the Japanese legation. The Daewongun briefly returned to power until Qing troops seized him.

While the new-style Special Skills Force was favoured, the old-style soldiers went unpaid for 13 months. When the rice they finally received was mixed with chaff and sand, they wrecked the house of Min Gyeom-ho, head of the Seonhyecheong, attacked the Japanese legation and killed the Japanese instructor of the new force. Joined by the urban poor they broke into the palace, and the queen fled to Janghowon in Chungju.
Gojong handed power to the Daewongun, who abolished the new reform office (Tongni gimu amun) and the Special Skills Force and restored the five old army commands. But Qing troops arrived, took the Daewongun away to Tianjin and restored the Min faction.
Qing troops then stayed in Seoul and advisers Ma Jianchang and Paul Georg von Möllendorff were sent to steer policy, while new trade regulations let Chinese merchants trade inland. With Japan, Joseon signed the Treaty of Jemulpo, paying an indemnity and allowing legation guards.
