 When Arabs conquered Armenia and Caucasus a new administrative and political unit formed known as Emirate of Armenia. This Emirate was divided itself to four subunits. Armenia I, II , III and also the special Emirate of Tiflis/Tbilisi. The internal borders were mostly the same as during the division of Armenia at 387 by Rome and Persia. So they not reflect necessarily ethnic borders but rather the political choices of Sassanian Persia. In fact it is during this period that the last Caucasian Albanian texts were written.While with the emergence of Tiflis Emirate many Iberians moved to west, where the nucleus of future unified Georgian kingdom emerged in the form of Tao-Klarjeti curopalate/kingdom.

Initially the Emirs were Armenians but later Arab Emirs were appointed.

Anyway the Emirate was enjoying large degree of autonomy.
