갑오개혁
July 23, 1894, Japanese troops attacked Gyeongbokgung Palace and took over the armory to help Hong-jip's forces. Hong-jip organized the First Cabinet and became the prime minister. He brought back Heungseon Daewongun from Qing, then proceeded with the Gabo Reform. He set up an organization for reform,'Gungukkimucheo', and became a governor of that organization. During the Gabo Reform, his cabinet abolished Gwageo, which was Joseon's imperial examination. Also, they reformed the monetary system, government system, and the weights and measures system.
