Before the invention of the name "Azerbaijan" for Aran and Shirvan, Russian imperial sources recognize only one Azarbaydzhan - A real Azarbaydzhan. The first volume of Russian Encyclopedia (pages 212 and 213), which was published in St. Petersburg nearly 102 years ago (1890), reads: "Azarbaydzhan, "Aturpatakan on pahlaviyskom language and Azarbadakan" in Armenian - a rich industrial northern province of Iran. It shares borders with the Iranian Kurdistan and the Iraqi Adjam to the south, with the Turkish Kurdistan and Armenia to the west, with Russian Armenia and South Caucasus in the north. Its boundaries are defined by the river Araks. If the name of Azerbaijan would apply to lands north of the Arax, is no doubt that this encyclopedia would use the name "Russian Azerbaijan, just as she used the notation "Turkish Kurdistan", "Iranian Kurdistan," Turkish Armenia ", or" Russian Армения”. Легко увидеть, что существовал только один Азарбайджан и это был Иранский Азарбайджан.

"As you can see, the name" Azerbaijan "was used with a specific purpose, which was revealed in subsequent years. Somewhere else in the same volume, Bartold wrote: "Where else, and whenever necessary the name, which can be called a region of Azerbaijan, one name may be used - "Aran" (page 703).
