The Lezgians are an ethnic group, living predominantly in southern Dagestan and north-eastern Azerbaijan, who speak the Lezgian language. In the 19th century, the term was used more broadly for all ethnic groups speaking non-Nakh Northeast Caucasian languages, including Caucasian Avars, Laks, and many others (although the Vainakh peoples, who were Northeast Caucasian language speakers were referred to as "Circassians").
