Ethnically it was "Turkic" and Azerbaijani ethnogenesis did not occur. I think I can find random sources to match with word "independent" but they lack context. The authors mention the topic in one sentence nor is work peer editted or credibility of authors established in relation Iranica. Like i said, how is source reliable that khanate was founded in 1747 if these persons were given a right to rule since 1604 by Safavi shahs???
