Iranian Azerbaijan - Iran
Iranian Azerbaijan is traditionally inhabited by Azeri people, an Iranian ethnic group speaking a Turkic language, Dating back to the Turkmanchay Treaty of 1828. Iran, known as Persia, ceded to Russian control of several Iranian Azerbaijani areas in the South Caucasus, now an independent country known as the Azerbaijan Republic.
The boundary between the Russian Empire and Iran was set at the Aras river, and this region, especially the eastern parts is probably one of the most beautiful places in the country, known for its friendly people, and great food.
Iranian Azerbaijan is now comprised of four provinces: Ardabil, Zanjan, East Azerbaijan and West Azerbaijan.
