In July 1894, the 8,000 Japanese troops captured the Korean king Gojong and occupied the Gyeongbokgung in Seoul. By 25 July, they had replaced the existing Korean government with members of the pro-Japanese faction. Even though Qing forces were already leaving Korea after they found themselves unneeded there, the new pro-Japanese Korean government granted Japan the right to expel Qing forces, and Japan dispatched more troops to Korea. The Qing Empire rejected the new Korean government as illegitimate.
