Southern Albania, again, is almost wholly mountainous, with the exception of the plains of Iannina and Arta; the most noteworthy feature is the rugged range of the Tchika, or Khimara mountains, which skirt the sea-coast from south-west to northeast, terminating in the lofty promontory of Glossa (ancient Acroceraunia).
The principal rivers are the Boyana, issuing from Lake Scutari, and consequently regarded as a continuation of the Montenegrin Moratcha, the Drin, formed by the confluence of the White and Black Drin, which, flowing respectively to the south and north through a long valley at the foot of the Shar range, take a westerly direction after their junction, the Matia, the Arzen, the Shkumb (ancient Genusos), the Simen (Apsos), formed by the junction of the Devol and Ergene, the Viossa (Aous), which owing to the trend of the Khimara range takes a north-westerly direction, the Kalamas (Thyamis) and the Arta (Arachthos), flowing south into the Ambracian Gulf.
In some districts there is a fixed price of blood; at Argyrokastro, for instance, the compensation paid by the homicide to the relatives of his victim is 1200 piastres (about £10), at Khimara 2000 piastres; once the debt has been acquitted amicable relations are restored.
Since the time of Ali Pasha, who broke the power of the local chieftains, southern Albania has been subject to the central Turkish power; before that period the mountaineers of Suli and Khimara enjoyed an independence similar to that of the Gheg tribes.
At Khimara (anc. Chimaera) the remains of an old Greek city may still be seen; at Santi Quaranta (anc. Onchesmos) the walls and towers of a later town are in good preservation.
The Bulgarians conquered the southern portion of the country and Epirus as far as Khimara; under their powerful tsar Simeon (893-927), who defeated the Servians, they established their rule on the Adriatic littoral, except at Durazzo, which remained Byzantine, and colonized these regions in great numbers.
