Gapsin Coup
During the reign of Gojong, real power initially belonged to his father the Heungseon Daewongun, who on one hand sought to reform corrupt state institutions but on the other hand pursued a policy of isolationism, opposing the opening of the country to Western and Japanese influences. From the 1870s onwards, Queen Min (known posthumously as Empress Myeongseong) became more dominant and pursued a policy of cautious modernisation and opening up. Her dominance was opposed by reactionaries and progressives alike. The Enlightenment Party (also known as Progressives) sought to modernise the country along Western and Japanese lines. These factional struggles led to the Imo Incident and Gapsin Coup, as well as increased foreign interference in Korean affairs.
