Russian Empire
The Russian Empire, also known as Imperial Russia or simply Russia, was an empire that existed across Eurasia and North America from 1721, following the end of the Great Northern War, until the Republic was proclaimed by the Provisional Government that took power after the February Revolution of 1917.
Imperial Russian Navy
Peter the Great established a modern Russian navy. During the Second Azov campaign of 1696 against Turkey, the Russians for the first time used 2 warships, 4 fireships, 23 galleys and 1300 strugs, built on the Voronezh River. After the occupation of the Azov fortress, the Boyar Duma looked into Peter's report of this military campaign. It passed a decree on October 20, 1696 to commence construction of a navy. This date is considered the official founding of the Imperial Russian Navy.
