Lezgins take the important place among the ethnoses belonging to the Caucasian language family. During the modern period it is settled in territory of the Azerbaijan Republic, basically in Kusar, Khachmaz, Geokchay, Gabala, Oguz, Ismaily areas. The name of ethnos is "lezgiyar". On historical sources ancestors of lezgins were ancient Albanian tribes called by "leg", occupied in territory between the Gudual and Samur rivers (now territory of Dagestan).

Not casually, that ethnicom "leg" meant all tribes speaking in lezgin language. One of these tribes was "lakzi". They lived in ancient historical area of Azerbaijan Maskuta to the West, in the top part of the Samur river, in territory under the "Lakz" name. Among local population, one of tribes of southern Dagestan was meant under "lakz" ethnicom. In XIX-XX centuries all population of Dagestan began to be called as lezgins, therefore the ethnos has adopted the name "lezgins". Lezgin language shares on three dialects: Kure, Akhti and the Cuba dialects.
