The Admiral Lazarev class was a pair of monitors built for the Imperial Russian Navy in the late 1860s, which designated them as armored turret frigates. Four ships were ordered, but the last two were significantly modified during construction and became the separate Admiral Spiridov class. The sister ships were assigned to the Baltic Fleet upon completion and remained there for their entire careers. Aside from one accidental collision, their careers were uneventful. They were reclassified as coast-defense ironclads in 1892 before they became training ships later that decade. The Admiral Lazarevs were stricken from the Navy List in 1907 and 1909; both were sold for scrap in 1912.
By late 1863, the Russian Admiralty Board had begun planning for the second generation of ironclads to succeed those ships then under construction. They ordered eight ships, two fully rigged seagoing types and six coastal defense ships, in March 1864. The British shipbuilder Charles Mitchell submitted four different designs for the coastal defense vessels, two broadside ironclads and two turret ships. The Shipbuilding Technical Committee decided in August that the broadside designs would be based on the hull shape of the earlier Pervenets-class ironclad for better seaworthiness, but they would be armed with fewer, but more powerful guns, than the numerous smoothbore guns of the older ships. Two variants were worked out that differed in the fineness of the hull and draft.
