Qarku_i_Prevezës
Demografia
Në rajonin e Çamërisë gjatë epokës vonë osmane, zona shqipfolës filloj prej pellgu i lumit Kalamai dhe duke zbritur në drejtim të jugut midis malit Kurilla dhe detit Jon, që përfshin qarkun moderne të Çamërisë. Ajo zonë të gjuhës shqipe vazhdoi më tej drejt jugut në drejtim të krahinës Frar dhe në lindje në drejtim të pellgut së lumit Llur dhe malin Sul, ose domethënë në qarkun e sotme të Prevezës. Chirol. Twixt Greek and Turk. 1881. f. 231-232. "The limits of the Albanian-speaking districts of Epirus south of the Kalamas may be roughly defined as follows: Starting from the Kalamas near the sharp bend which that river takes to the north at the foot of Mount Lubinitza, they follow the crest of the amphitheatrical range of Suli as far as the gorge of the Acheron. In that neighbourhood, probably owing to the influence which the Suliote tribe at one time enjoyed, they drop over to the east into the valley of the Luro, and follow its basin as far as the peninsula on which Prevesa, is situated, where the Greek element resumes its preponderancy. Within these outer limits of the Albanian tongue the Greek element is not unrepresented, and in some places, as about Paramythia, for instance, it predominates; but, on the whole, the above- defined region may be looked upon as essentially Albanian. In this, again, there is an inner triangle which is purely Albanian—viz., that which lies between the sea and the Kalamas on the one hand and the waters of the Vuvo on the other. With the exception of Parga and one or two small hamlets along the shore, and a few Greek chifligis on Albanian estates, the inhabitants of this country are pure Tchamis—a name which, notwithstanding Von Hahn’s more elaborate interpretation. I am inclined to derive simply from the ancient appellation of the Kalamas, the Thyamis, on both banks of which stream the Albanian tribe of the Tchamis, itself a subdivision of the Tosks, has been settled from times immemorial. From the mountain fastnesses which enclose this inner triangle, the Tchamis spread out and extended their influence east and south; and the name of Tchamouria, which is especially applied to the southernmost Albanian settlements in Epirus, was probably given to that district by themselves as an emphatic monument of their supremacy; but it cannot belong less rightfully to the centre, where they hold undivided sway."

"Τα αλβανικά αποτελούσαν την κυρίαρχη ομιλούμενη γλώσσα προς τα βόρεια μιας γραμμής που άρχιζε από την περιοχή των Αγίων Σαράντα, περνούσε δίπλα από τις πόλεις Δέλβινο και Αργυρόκαστρο (ανάμεσα στα χωριά Κολορτσί και Δερβιτσάνη) και φτάνοντας στην Πολίτσανη, όπου και το βορειότερο άκρο της επαρχίας του Πωγωνιού, στρεφόταν προς τα νοτιοανατολικά και ακολουθούσε περίπου την πορεία των σημερινών ελληνοαλβανικών συνόρων. Τα εδάφη που βρίσκονται νότια απ' αυτή τη γραμμή, δηλαδή το μεγαλύτερο τμήμα της κοιλάδας της Δρόπολης, τα βορινά χωριά του Πωγωνιού, τα περισσότερα χωριά της Ρίζας του Δελβίνου (Δρόβιανη, Μάλτσανη, Δίβρη, Λεσινίτσα) και ο κάμπος του Βούρκου μεταξύ Δελβίνου και Αγίων Σαράντα ορίζουν μέχρι σήμερα την έκταση των ελληνικών μειονοτικών περιοχών στην Αλβανία.
