Japanese occupation of Gyeongbokgung
The Japanese occupation of Gyeongbokgung Palace (Korean: 일본군의 경복궁 점령) or the Gabo Incident occurred on 23 July 1894, during the ceasefire of the Donghak Peasant Revolution and the beginning of the First Sino-Japanese War. Imperial Japanese forces led by Japanese Minister Plenipotentiary to Korea Ōtori Keisuke and Ōshima Yoshimasa occupied Gyeongbokgung palace to restore King Gojong's father Heungseon Daewongun and establish a pro-Japanese government under Kim Hong-jip and the Enlightenment Party's administration.
