Karachays and Balkars spoke similar Turkic languages. East of the Balkars were the Ossetians – Iranian speakers descended from the ancient Alans who controlled the future Georgian Military Road and had a growing Christian minority. East of the future highway was a north-south band of Ingush – NECLS similar to the Chechens. The numerous Chechens to the east were later to wage the long Murid War against the Russians. For the small groups south of the Ingush-Chechens see South Slope below. To the east along the coast were the Turkic Kumyks. Mountain Dagestan: All the peoples of mountain Dagestan were NECLS except the Tats. In the northwest were a number of small language groups (Tsez people (Dido) and Andi people), similar to the Avars. To their southeast were the numerous Avars with a khanate at Khunzakh who fought in the Murid War. Southeast were the Dargins and west of them the Laks who held the Kumukh Khanate. Southeast along the Samur were the Lezgins with many subgroups and then the Iranian-speaking Tats down to Baku. Caspian Coast: From Astrakhan to the Terek River there were the Buddhist Kalmyk nomads. Along the Terek were the isolated Terek Cossacks. From the Terek to Derbent were the Turkic-speaking Kumyks with a state at Tarki. The town of Derbent itself had a majority Persian () population, as it had for many centuries, until the late 19th century. On the coastal plain south of Derbent was a mixed population, mostly Azeri ("Transcaucasian Tatar"), and further south to Baku were the Iranian-speaking Tats. When Baku became a boom town the Tats retained a majority only in the mountains. The Mountain Jews, who had a number of villages inland from the coast, spoke a form of Tat called Judeo-Tat. The lowlands south of Baku were held by Azerbaijanis, Turkic-speaking Shiites. On both sides of the current Iranian border were the Iranian-speaking Talysh. Based on genetic studies the Gilaki and Mazanderani ethnic groups in northern Iran (near the Caspian Sea) have been proven to be genetically similar to Armenians, Georgians and Azeris. This indicates that the Gilaki and Mazanderani ethnic groups are people that immigrated from the Caucasus region to what is now northern Iran. South Slope: Black Sea coast: In the northwest the mountains came down to the sea and the population was Circassian. Southward the coastal plain broadened and the population was Abkhazians – similar to
