Analysis of information sources in references of the Wikipedia article "Arran (Caucasus)" in English language version.
The province of Arran, classical Albania, lay within the great triangle of land formed by the junction of the Kur and the Aras, of which the greater portion now forms part of the Soviet Socialist Republic of Azerbaijan, the remainder belonging to the Republic of Armenia
The origin of the name Arrān, Georgian Rani, Greek 'Αλβανοὶ, and Armenian Alwankʿ (people), is unknown. (In some Classical authors one finds the form Arian/Aryan, and in Arabic sources one can find al-Ran).
The name Azerbaijan was also adopted for Arrān, historically an Iranian region, by anti-Russian separatist forces of the area when, on 26 May 1918, they declared its independence and called it the Democratic Republic of Azerbaijan.
