Azerbaijan, Russian suzerainty

After a series of wars between the Russian Empire and Iran, the treaties of Gulistan (1813) and Turkmenchai (1828) established a new border between the empires. Russia acquired Baku, Shirvan, Ganja, Nakhichevan (Nax�ivan), and Yerevan. Henceforth the Azerbaijani Turks of Caucasia were separated from the majority of their linguistic and religious compatriots, who remained in Iran.
