What happened

Foreign merchants and rising taxes to fund reform efforts had pushed Korean peasants toward the breaking point by the early 1890s. The Donghak (Tonghak) movement, a religious sect founded in 1860 blending Confucian teaching with Daoism, Buddhism, and some Christian influence, provided the organizing framework. In 1894 an attack on a corrupt local magistrate in the south swelled into a mass uprising against corrupt officials nationwide. A panicked Korean government requested Chinese military help, but the rebellion was already largely under control by the time Chinese troops arrived. Japan seized the opening to send its own troops and install a pro-reform, pro-Japanese government, then drove out the Chinese forces already present, launching the First Sino-Japanese War. China was defeated and signed the Treaty of Shimonoseki in April 1895, formally recognizing Korea as fully independent and surrendering all Chinese claims to suzerainty over it.

Why it matters

The Donghak Rebellion was a genuine grassroots peasant uprising against corruption, but its real historical consequence was to give Japan the pretext to eliminate Chinese influence over Korea entirely, clearing the way for unchecked Japanese domination of the peninsula that would end in outright annexation sixteen years later.

How we know

The Donghak Rebellion and the resulting Sino-Japanese War are documented in Korean, Japanese, and Chinese government records of 1894-1895, including the text of the Treaty of Shimonoseki itself, which explicitly ended China's centuries-old claim to suzerainty over Korea.
