Q. In which year, the first Sino-Japanese war was started?
Answer: 1894
Notes: The first Sino-Japanese War began in 1894 and ended in 1895. The conflict arose from a dispute over control of Korea, which was a tributary state of China at the time. Japan, which had rapidly modernized and was seeking to expand its influence in the region, ultimately defeated China and gained control of Korea, Taiwan, and the Liaodong Peninsula as a result of the war. The war marked the beginning of Japan's rise as a major world power and the decline of the Qing dynasty in China.
