The Russo-Japanese War of 1904-5 was the outcome of competition between two imperial empires seeking to dominate the area around Manchuria and Korea. The war was fought at the end of Russia’s supply line and was made more difficult for the Russians by the 1905 Revolution in Russia. Japan suffered heavy casualties, about 100,000, but Russia lost more heavily, including the Baltic Fleet which was sunk in the Battle of Tsushima. As a consequence, the two nations continued to view each other as potential enemies until World War II.
