The First Sino-Japanese War, or the First China–Japan War, was a conflict between the Qing dynasty of China and the Empire of Japan primarily for influence over Korea. In China it is commonly known as the Jiawu War. After 6 to 7 months of unbroken successes by Japanese land and naval forces and the loss of the ports of Lüshunkou and Weihaiwei, the Qing government sued for peace in February 1895 and signed the Treaty of Shimonoseki two months later, ending the war.
