During the Russo-Japanese War, sailors start a mutiny aboard the Russian battleship Potemkin.
The Russian battleship Potemkin (Russian: , romanized: Kniaz Potyomkin Tavricheskiy, "Prince Potemkin of Taurida") was a pre-dreadnought battleship built for the Imperial Russian Navy's Black Sea Fleet. She became famous when the crew rebelled against the officers in June 1905 (during that year's revolution), which is now viewed as a first step towards the Russian Revolution of 1917. The mutiny later formed the basis of Sergei Eisenstein's 1925 silent film Battleship Potemkin.
After the mutineers sought asylum in Constana, Romania, and after the Russians recovered the ship, her name was changed to Panteleimon. She accidentally sank a Russian submarine in 1909 and was badly damaged when she ran aground in 1911. During World War I, Panteleimon participated in the Battle of Cape Sarych in late 1914. She covered several bombardments of the Bosphorus fortifications in early 1915, including one where the ship was attacked by the Ottoman battlecruiser Yavuz Sultan Selim Panteleimon and the other Russian pre-dreadnoughts present drove her off before she could inflict any serious damage. The ship was relegated to secondary roles after Russia's first dreadnought battleship entered service in late 1915. She was by then obsolete and was reduced to reserve in 1918 in Sevastopol.
Panteleimon was captured when the Germans took Sevastopol in May 1918 and was handed over to the Allies after the Armistice in November 1918. Her engines were destroyed by the British in 1919 when they withdrew from Sevastopol to prevent the advancing Bolsheviks from using them against the White Russians. The ship was abandoned when the Whites evacuated the Crimea in 1920 and was finally scrapped by the Soviets in 1923.
The Russo-Japanese War ( Japanese: 日露戦争, romanized: Nichiro sensō, lit. 'Japanese-Russian War';Russian: Ру́сско-япóнская войнá, romanized: Rússko-yapónskaya voyná) was fought between the Empire of Japan and the Russian Empire during 1904 and 1905 over rival imperial ambitions in Manchuria and the Korean Empire. The major theatres of military operations were located in Liaodong Peninsula and Mukden in Southern Manchuria, and the seas around Korea, Japan, and the Yellow Sea.
Russia sought a warm-water port on the Pacific Ocean both for its navy and for maritime trade. Vladivostok remained ice-free and operational only during the summer; Port Arthur, a naval base in Liaodong Province leased to Russia by the Qing dynasty of China from 1897, was operational year round. Since the end of the First Sino-Japanese War in 1895, Japan had feared Russian encroachment would interfere with its plans to establish a sphere of influence in Korea and Manchuria. Russia had pursued an expansionist policy east of the Urals, in Siberia and the Far East, since the reign of Ivan the Terrible in the 16th century.Seeing Russia as a rival, Japan offered to recognize Russian dominance in Manchuria in exchange for recognition of Korea as within the Japanese sphere of influence. Russia refused and demanded the establishment of a neutral buffer zone between Russia and Japan in Korea north of the 39th parallel. The Imperial Japanese Government perceived this as obstructing their plans for expansion into mainland Asia and chose to go to war. After negotiations broke down in 1904, the Imperial Japanese Navy opened hostilities in a surprise attack on the Russian Eastern Fleet at Port Arthur, China on 9 February [O.S. 27 January] 1904.
Although Russia suffered a number of defeats, Emperor Nicholas II remained convinced that Russia could still win if it fought on; he chose to remain engaged in the war and await the outcomes of key naval battles. As hope of victory dissipated, he continued the war to preserve the dignity of Russia by averting a "humiliating peace". Russia ignored Japan's willingness early on to agree to an armistice and rejected the idea of bringing the dispute to the Permanent Court of Arbitration at the Hague. The war was eventually concluded with the Treaty of Portsmouth (5 September [O.S. 23 August] 1905), mediated by US President Theodore Roosevelt. The complete victory of the Japanese military surprised international observers and transformed the balance of power in both East Asia and Eastern Europe, resulting in Japan's emergence as a great power and a decline in the Russian Empire's prestige and influence in eastern Europe. Russia's incurrence of substantial casualties and losses for a cause that resulted in humiliating defeat contributed to a growing domestic unrest which culminated in the 1905 Russian Revolution, and severely damaged the prestige of the Russian autocracy. The war also marked the first victory of an Asian country against a Western power in modern times.
