Nakh peoples are a group of historical and modern ethnic groups speaking (or historically speaking) Nakh languages and sharing certain cultural traits. Today, they reside almost completely in the eastern parts of North Caucasus, but historically, certain areas of the South Caucasus may have also been Nakh.
The only healthy, living branch of the Nakh languages are now the Vainakh languages (spoken by the Vainakh peoples, namely Chechens, Ingush and Kist), due to the extinction of other peoples. The only non-Vainakh modern Nakh people are the Bats people in Northeast Georgia, but they are largely assimilated and their language is highly endangered.
Although the Vainakh are only a branch of Nakh peoples, due to the present-day situation, where the only well-known Nakh are Vainakh, the words Vainakh and Nakh are frequently confused. Hence the word Vainakh is frequently, but mistakenly applied to historical non-Vainakh peoples.
The early history of the Nakh peoples has been tentatively reconstructed from linguistic analysis and archaeological evidence.
A characteristic feature of Vainakh architecture in the Middle Ages, rarely seen outside Chechnya and Ingushetia, was the Vainakh tower, a kind of multi-floor structure that was used for dwelling or defense (or both). Nakh tower architecture and construction techniques reached their peak in the 15th–17th centuries.
Residential towers had two or three floors, supported by a central pillar of stone blocks, and were topped with a flat shale roofing. These towers have been compared to the prehistoric mountain settlements dating back to 8000 BC.
Military ("combat") towers were 25 meter high or more, with four of five floors and a square base approximately six meters wide. Access to the second floor was through a ladder. The defenders fired at the enemy through loopholes and the top of the tower had mashikul – overhanging small balconies without a floor. These towers were usually crowned with pyramid-shaped roofing built in steps and topping with a sharpened capstone.
