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 over influence in Korea. In Chinese it is commonly known as the Jiawu War. After more than six 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 unequal Treaty of Shimonoseki two months later, ending the war.
