See it on the Korean History map →What happened
China and Japan both sent troops to Korea during the 1894 peasant uprising, and neither would leave. On July 23 Japanese troops occupied Gyeongbokgung palace; two days later Japan sank a Chinese troop transport off Pungdo. Japan's modernized forces won at Seonghwan, Pyongyang and the mouth of the Yalu, then pushed into Manchuria and Shandong. The Treaty of Shimonoseki (April 1895) made China recognize Korea's "full and complete independence," cede Taiwan and pay a huge indemnity. Koreans call it Cheong-il jeonjaeng (청일전쟁).
Why it matters
It ended China's centuries-old role as Korea's overlord and made Japan the leading power in Korea, a decisive step toward annexation in 1910.
How we know
Military and diplomatic archives of both countries, the treaty text, and journalists' and Korean officials' accounts of fighting on Korean soil.
Still debated
Whether Japan's leaders planned the war in advance or seized an opportunity is debated; Korean civilian losses were poorly recorded.
Connections (4)
▸Donghak Peasant Revolution drew in Qing and Japanese troops, triggering First Sino-Japanese WarWell documented
The connection
After the rebels took Jeonju, the court asked China for troops. Under the 1885 Tianjin Convention, Japan could send troops too, and it landed a larger force. When the rebels agreed a truce, Japan refused to withdraw, demanded reforms, seized the palace and attacked Chinese forces.
When and how
June–July 1894; Qing troops landed at Asan, Japanese at Incheon; fighting began off Pungdo on July 25.
How we know
Diplomatic records of Korea's request, China's notice to Japan and Japan's response under the Tianjin Convention.
Debates and open questions
Whether Japan would have found another pretext without the uprising is debated; many historians think it was already seeking war.
▸First Sino-Japanese War ended Qing suzerainty over JoseonWell documented
The connection
For centuries Joseon kings received investiture from Chinese emperors and sent tribute missions. The Treaty of Shimonoseki (1895) made China accept Korea's 'full and complete independence' and end the tribute. In practice it swapped Chinese oversight for Japanese pressure.
When and how
Shimonoseki, Japan, April 17, 1895; Li Hongzhang for China, Itō Hirobumi for Japan.
How we know
Article 1 of the treaty; soon after, Koreans tore down Yeongeunmun, the gate where Chinese envoys had been received, and later built Independence Gate there.
Debates and open questions
How much the tributary tie limited Korea's real independence before the 1880s is debated; many see it as largely ritual until then.
▸Gabo Reform was pushed by Japan during First Sino-Japanese WarWell documented
The connection
After occupying Gyeongbokgung on July 23, 1894, Japan installed a reform cabinet, with the Daewongun briefly as figurehead, and the Deliberative Council began issuing decrees as the war started. Japanese minister Inoue Kaoru later pressed a 20-point reform plan, and battlefield wins gave Japan leverage.
When and how
Seoul, from July 1894; Japanese ministers Ōtori Keisuke and then Inoue Kaoru.
How we know
Japanese legation records and the timing: the Council began work on July 27, two days after fighting started.
Debates and open questions
The balance between Japanese direction and Korean reformers' own initiative is the core debate about the Gabo Reform.
▸Assassination of Empress Myeongseong (Eulmi Incident) came in the aftermath of First Sino-Japanese WarWell documented
The connection
Japan's victory should have left it dominant, but in April 1895 Russia, France and Germany forced it to hand back the Liaodong peninsula. Seeing Japan humbled, Queen Min's circle turned to Russia and pushed out pro-Japanese ministers. Japan's new minister, Miura Gorō, answered with the plot to kill her.
When and how
Seoul, April–October 1895; the Triple Intervention came on April 23, 1895.
How we know
Diplomatic records of the court's Russian contacts and the Japanese consul Uchida Sadatsuchi's report on the plot.
Debates and open questions
Whether Miura's plot was his own initiative or approved by leaders in Tokyo remains debated.
