1600-1753: In 1645 a regiment was moved to Tersk (it has been re-established early in the century). Kabardia split into two factions, the pro-Russian Baksan and pro-Crimean Kashkatau (originally the alliances were opposite, but they switched sides some time after 1722.). One side brought in Russians from Astrakhan. The Nekrasov Cossacks settled on the Kuban about 1711. More Cossacks settled on the Terek and Kizlyar was founded in 1736. In 1739 Kabardia was declared a buffer state between the Russian and Ottoman empires. In 1744 Koltsov and 400 Cossacks arrived to support the Baksan faction. Another force was sent in 1753.
