The second part of the book is devoted to ethnogenetical tracing and main questions of ethnopolitical history specifically for Bulgaro-Tatars, who historically composed the Tatars of the Ural-Itil region, Siberian Tatars and Lithuanian Tatars, leaving aside the subject of Tatars in general. It also brings some clarity in several ethnogenetical aspects for the Ancient Tatars, Mongolo-Tatars, Tatars, Kipchak Khanate (Altyn Orda) Tatars, Türko-Tatars, Crimean Tatars and Dobrudja (Budjak) Tatars.

The first part of this book attempts to reveal the most ancient ethnic roots of Türkic-speaking tribes and peoples: Subars, Sumers, Kangars, Horasmians, Parthians, Sogdians, Arians, Tocharians-Taurians, Kusans-Kushans, Sakas-Scythians, Sarmatians, Etruscans, Onogurs, Alans-Ases, Huns-Süns, etc. The ethnic roots of the Türks in the ethnically Turkic states of late period are mentioned only in general, because they are relatively well addressed in other works. The first part of the book can be useful in retracing ethnic history not solely for Bulgaro-Tatars, but also for other Türkic-speaking peoples.
