ETHNIC AND POLITICAL HISTORY OF NAKHCHIVAN: ARMENIAN FIGMENTS AND HISTORICAL REALITIES
Suitable natural geographical features of Nakhchivan created an opportunity for the humans to inhabit here since Stone Age. Material culture samples of Stone Age found in Sabir-Diza (Ordubad region), Shahtakhti (Kangarli region) and Ovchulartapasi (Sharur region) settlements during archeological researches prove the fact that old humans had settled in Nakhchivan million years ago. Excavations in Gazma cave show that life in Nakhchivan still existed in the middle and last phases of Paleolithic period. The study of the signs characteristic for upper Paleolithic period prove that ancient Gazma inhabitants were on the eve of tribal society formation.
