The war developed from Russia’s and Japan’s rivalry for dominance in Korea and Manchuria. After the First Sino-Japanese War, Japan acquired the Liaodong Peninsula from China, but European powers forced Japan to return it. China subsequently leased it to Russia. The Russo-Japanese War began when Japan attacked Russian warships at Port Arthur, on the peninsula.
