or "Caucasian Albania" was an ancient empire
that covered what is now southern Dagestan
and northern Azerbaijan
Some historians say that the Albanians of the Balkans and the Lezgins of the Caucasus are the same people, and that the Albanians moved to the Balkans from the Caucasus around the 10th century.
