This Google Map shows the Shahdagh (Şahdağ) peoples of the north Caucasus, in what is today Azerbaijan.
There are four ethnic groups under the umbrella of the generic term Shahdagh, each of which has its own language.
The colour code used on the map is as follows:
Buduq (Budukh): green markers
Cek (Dzhek): red markers
Xinaliq (Khinalug): purple markers
Yergüc (Yerguj): blue markers
The regular pins on the map show the original native highland settlements. The circles show the diaspora settlements, which are mainly although not entirely in the lowlands and largely the result of Soviet era displacement.
