the Latins, who live in the Italian regions of our Empire beyond Western Rome, quite suddenly became enemies when Michael Dokeianos insanely directed his command against their leaders..." Caucasian theory One of the earliest theories on the origins of the Albanians, now considered obsolete, incorrectly identified the proto-Albanians with an area of the eastern Caucasus, separately referred to by classical geographers as Caucasian Albania, located in what roughly corresponds to modern-day southern Dagestan, northern Azerbaijan and bordering Caucasian Iberia to its west. This theory conflated the two Albanias supposing that the ancestors of the Balkan Albanians (Shqiptarët) had migrated westward in the late classical or early medieval period. The Caucasian theory was first proposed by Renaissance humanists who were familiar with the works of classical geographers, and later developed by early 19th-century French consul and writer François Pouqueville. It was soon rendered obsolete in the 19th century when linguists proved Albanian as being an Indo-European, rather than Caucasian language. Pelasgian theory In terms of historical theories, an outdated theory is the 19th century theory that Albanians specifically descend from the Pelasgians, a broad term used by classical authors to denote the autochthonous, pre-Indo-European inhabitants of Greece and the southern Balkans in general. However, there is no evidence about the possible language, customs and existence of the Pelasgians as a distinct and homogeneous people and thus any particular connection to this population is unfounded. This theory was developed by the Austrian linguist Johann Georg von Hahn in his work Albanesische Studien in 1854. According to Hahn, the Pelasgians were the original proto-Albanians and the language spoken by the Pelasgians, Illyrians, Epirotes and ancient Macedonians were closely related. In Hahn's theory the term Pelasgians was mostly used as a synonym for Illyrians. This theory quickly attracted support in Albanian circles, as it established a claim of predecence over other Balkan nations, particularly the Greeks. In addition to establishing "historic right" to territory this theory also established that the ancient Greek civilization and its achievements had an "Albanian" origin. The theory gained staunch support among early 20th-century Albanian publicists. This theory is rejected by scholars today. In contemporary times with the Arvanite revival of the Pelasgian theory, it has also been recently borrowed by other Albanian speaking populations within and from Albania in Greece to counter the negative image of their communities.
