Azerbaijan (pronounced /ˌæzərbaɪˈdʒɑːn/; Azerbaijani: Azərbaycan), formally the Republic of Azerbaijan (Azerbaijani: Azərbaycan Respublikası), is a country in the Caucasus region of Eurasia. Located at the crossroads of Western Asia and Eastern Europe, it is bounded by the Caspian Sea to the east, Russia to the north, Georgia to the northwest, Armenia to the west, and Iran to the south. The exclave of Nakhichevan is bounded by Armenia to the north and east, Iran to the south and west, while having a short borderline with Turkey to the northwest. The Nagorno-Karabakh region in the southwest of Azerbaijan proper declared itself independent from Azerbaijan in 1991, but it is not recognized by any nation and considered a legal part of Azerbaijan.
