(Redirected from Ganghwa Island affair)
The 'Ganghwa Island incident' (Japanese: 江華島事件, Korean: 운요호 사건 "Unyo-ho sageon" meaning "Unyo incident") was an armed encounter between the
Joseon Dynasty (Yi Dynasty, Korea) and Japan which occurred in the vicinity of
Ganghwa Island on September, 20 1875.
Background
In the second half of the 19th century, Korea was the scene for a power struggle between several imperial powers including the
Russians and the
French, as well as the Chinese and the Japanese.
The
Meiji Restoration of
1868 ended the 265-year-old feudalistic
Tokugawa shogunate in Japan. The new government of Japan sent a messenger holding a letter with the sovereign's message which informed of the founding of a new administration of Japan to the government of the
Joseon Dynasty of the Korean Peninsula on December, 19th 1868.

The characters in the sovereign letter which
Joseon(Korea) refused.
However, the Joseon Dynasty refused to receive the letter because it contained the
Chinese characters '' and ''. According to the political system of the day, only the
Chinese emperor was allowed to use these characters, as they signified the imperial authority of China in the region. Hence, their use by a Japanese sovereign was considered unacceptable by Joseon, as it implied he was an equal of the Chinese emperor.
The
Qing Dynasty prompted Joseon to receive the sovereign letter from Japan, because Qing knew the power of Japan at that moment. Despite government-level negotiations held
1875 in
Busan, no substantial progress was made. Instead, tension grew as Joseon continued to refuse to recognize Japan's claims of equality with China.
The incident

Japanese landing from the ''Unyo'' at Ganghwa island.
In
1875, the
''Unyo'', a small Japanese warship under the command of
Inoue Yoshika, was dispatched to survey coastal waters without Korean permission.
On September 20 the ship reached
Ganghwa Island, which had been a site of violent confrontations between Korean forces and foreign forces in the previous decade. In 1866, the island was briefly occupied during the
French Campaign against Korea, and also in 1871 subject to an
American intervention. The memories of those confrontations were very fresh, and there was little question that the Korean garrison would shoot at any approaching foreign ship. Nonetheless, Commander Inoue ordered a small boat launched – allegedly in search of drinkable water. The Korean forts opened fire. The Unyo brought its superior firepower to bear and silenced the Korean guns. Then it attacked another Korean port and withdrew back to Japan.
After the incident, the
Imperial Japanese Navy blockaded the immediate area and demanded an official apology from the Joseon government, which was concluded with the signing of
Treaty of Ganghwa.
