1904 – 1905
An imperial war between Japan and Russia over dominance in Korea and Manchuria, fought largely on Chinese and Korean territory without meaningful consent from either society. Japan opened hostilities with a surprise naval attack at Port Arthur and won costly land campaigns and a decisive naval victory at Tsushima. The Treaty of Portsmouth recognized Japan’s paramount interests in Korea and transferred Russian leases and railway rights in southern Manchuria, helping enable Japan’s 1910 annexation of Korea. Defeat intensified Russia’s 1905 revolutionary crisis but did not alone cause it. Japan’s victory over a European empire resonated globally, even as it expanded Japan’s own colonial empire.
