Imperial Russian Navy

The Imperial Russian Navy (Russian: Российский императорский флот) operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until dissolved in the wake of the February Revolution of 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Second Azov campaign in 1696. It expanded in the second half of the 18th century and reached its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size.

The Imperial Navy drew its officers from the aristocracy of the Empire, who belonged to the state Russian Orthodox Church. Young aristocrats began to be trained for leadership at a national naval school. From 1818 on, only officers of the Imperial Russian Navy were appointed to the position of Chief Manager of the Russian-American Company, based in Russian America (present-day Alaska) for colonization and fur-trade development. Although the early Imperial Navy initially employed paid foreign sailors, the government began to recruit native-born sailors as conscripts, drafted (as were men to serve in the army). Service in the navy was lifelong. Many naval commanders and recruits came from Imperial Russia's non-Russian lands with maritime traditions—Finland and (especially) the Baltic governorates.

The Russian Navy went into a period of decline due to the Empire's slow technical and economic development in the first half of the 19th century. It had a revival in the latter part of the century during the reign of Emperor Nicholas II (r. 1894–1917), but most of its Pacific Fleet (along with the Baltic Fleet sent to the Far East) was destroyed in the humiliating Russo-Japanese War of 1904-1905.

The navy had mixed experiences during the First World War, with the Germans generally gaining the upper hand in the Baltic Sea, while the Russians took control of the Black Sea. The Russian Revolution marked the end of the Imperial Navy; its officers had mostly aligned with the emperor, and the sailors split to fight on either side during the Russian Civil War of 1917-1922. The Soviet Navy, established as the Red Fleet in 1918 after the Revolution, took over the available surviving ships.

Strategically, the Imperial Russian Navy faced two overarching issues: the use of ice-free ports and open access to the high seas. Saint Petersburg and the other Baltic ports, as well as Vladivostok, could not operate in winter, hence the push for Russia to establish naval facilities on the Black Sea coast and (eventually) at Murmansk. And even substantial naval forces in the Baltic Sea remained confined by the lack of free access to the Atlantic via the Øresund, just as the Black Sea Fleet could not always rely on passage through the Bosphorus and the Dardanelles. As a result, separate naval groupings developed in relative isolation in the Baltic, the Black Sea, the Russian Far East and the Arctic.
