The aim of forming the Islamic Democratic Party of Mosavat in Baku was to establish a large Islamic state under the leadership of Asia Minor Turks. This party announced the independence of part of Caucasus under the title of Independent Republic of Azerbaijan in Ramadan of 1336 AH- Tir of 1297 Hijri Shamsi, June, 1918. After the collapse of Mosavat Party and dominance of Bolsheviks over Causasus, Bolsheviks preserved the name of Azerbaijan for that territory and that state was named Soviet Socialist Republic of Azarbaijan, while that land was never called Azerbaijan, while that land was never called Aran.It seems that naming part of Caucasus that is Aran, as Azerbaijan in the future could become a pretext for the statesmen on the other side of Aras River to claim that Azerbaijan has been divided into two parts and if possible, fulfill their territorial intentions about Azerbaijan.This move become fruitful with the formation of Democratic Party of Azerbaijan in Tabriz led by Seyed Jafar Pishevari who was openly supported by Mir Jafar Bagherof president of Soviet Azerbaijan and Moscow leaders and revealed its true nature.The heads of the party were preparing to separate Azerbaijan from Iran. But calculated measures taken by Ahmad Ghavam AI-Saltaneh prime minister of Iran at that time who made use of political conditions, prepared the grounds for evacuating Soviet Red Army forces from Iran and eventual disintegration of the Democratic Party of Azerbaijan.
