The territory where the town existed corresponded to modern northeastern Dagestan (Kizlyarsky District, the left bank of the Stary Terek channel northeast of Kizlyar).
[2] The town of Terek was a stronghold serving the expansion of the Russian state in the North Caucasus and the Western Caspian region, its location made it an important military and strategic point on the southern outskirts of the country.
In the first years of the 18th century, the successful development of the Terek city was interrupted as a result of the raid of the Lesser Nogai Horde (Old Russian "Kuban Tatars").
[3][4] In 1708, North Caucasian rebels led by the Bashkir prince Murat Kuchukov stormed the fortress and captured most of it, but failed to take the citadel.
In 1721, a large army of Chechens and Kumyks led by the Turlov prince Aidemir Bardykhanov attacked the fortress again, but were repelled by the garrison with heavy losses.
