Republic of Artsakh
Armenian people have lived there since classical antiquity. In the 11th century the Seljuk invasion swept over the Middle East, including the South Caucasus. Nomadic Turkic Oghuz Seljuk tribes, which also include the Azerbaijanis, came during this invasion. They became dominant in Nagorno-Karabakh. From this time, until the beginning of the 20th century, these tribes used Mountainous Karabakh as their summer pastures. They stayed there for about four to five months per year, and in fact, they owned the region.
