The modern Russian Navy was created at the initiative of Peter the Great. During the Second Azov campaign of 1696 against the Ottoman Empire, the Russians employed for the first time 2 warships, 4 fireships, 23 galleys and 1300 strugs, built on the Voronezh River. After the Azov fortress was taken, at Peter I's request the Boyar Duma, understanding the vital importance of a navy for successful warfare, on 20 October 1696 adopted a decree on commencing the construction of a regular navy.
