The House of Romanov (Russian: Рома́нов, ro-MAHN-off) was the second and last imperial dynasty to rule over Russia, reigning from 1613 until the 1917 overthrow of the monarchy during the February Revolution. The later history of the Imperial House is sometimes referred to informally as the House of Holstein-Gottorp-Romanov.
The Duke of Holstein-Gottorp, who was himself a member of a cadet branch of the Oldenburgs, married into the Romanov family early in the 18th century; all Romanov Tsars from the middle of that century to the revolution of 1917 were descended from that marriage. Though officially known as the House of Romanov, these descendants of the Romanov and Oldenburg Houses are sometimes referred to as Holstein-Gottorp-Romanov.
