Analysis of information sources in references of the Wikipedia article "葉里溫汗國" in Chinese language version.
Serious historians and geographers agree that after the fall of the Safavids, and especially from the mid-eighteenth century, the territory of the South Caucasus was composed of the khanates of Ganja, Kuba, Shirvan, Baku, Talesh, Sheki, Karabagh, Nakhichivan and Yerevan, all of which were under Iranian suzerainty.
Indeed, since the formation of the Ghaznavids state in the tenth century until the fall of Qajars at the beginning of the twentieth century, most parts of the Iranian cultural regions were ruled by Turkic-speaking dynasties most of the time. At the same time, the official language was Persian, the court literature was in Persian, and most of the chancellors, ministers, and mandarins were Persian speakers of the highest learning and ability.
