The area, known today as Azerbaijan, was known to the ancients as "ATROPAT"ATAR and PATAR. "Atar" means fire and "Patar" means nation in the ancient Pars(Farsi) language. When the words are joined, they mean the "Nation of Fire". Thisname was given to the region, according to the well-known Arab historian, Tabari,because of the great fire that was fed by natural gases coming out of the earth.Therefore, in remote antiquity, Azerbaijan was the holy land of the worshippers ofthe eternal fire, and the rich coast near Baku (the capital city) was the place ofpilgrimage for many believers. (Altstadt, Audrey L., 1992.) The origin of AzerbaijaniTurks is still somewhat controversial among historians despite that many resenthistorical studies have been present. Some relate them to Persians, some to Hun-Khazars who were called as Turks in time, according to Tabari. Russian andAzerbaijani historians relate Azeris to the Caucasian Albanians who might be theancestors of Azeris. (Audrey L. Altstadt’s,) A well-known traveler Tur Heyerdal whofinds a possible historical relationship between Norwegians and Azerbaijanis,claiming that both nations might share the historical relationship with CaucasianAlbanias, has conducted an archeological research in Azerbaijan, especially, in theGobustan caves and in Sheki region where Caucasian Albanians ruled until 9thcentury. The same Albanians according to historical traces that were found in oldCaucasian Albanian ( present Caucasian areas) areas today thought to be related tothe Vikings.
