The Emperor and Autocrat of all Russia (Russian: Император и Самодержец Всероссийский), also translated as Emperor and Autocrat of all the Russias, was the official title of the Russian monarch from 1721 to 1917. The title originated in connection with Russia's victory in the Great Northern War (1700–1721) and appeared as an adaptation of the tsar's title under the accepted system of titling in Europe. The title was transformed from the previous title of tsar and grand prince of all Russia. The old title tsar (or tsaritsa) continued to be popularly used to refer to the emperor (or empress) until the monarchy was abolished in 1917. Source: Wikipedia (en)
