Note 201 — Chapter X · LANGUAGE PROBLEMS OF THE BALKAN PENINSULA
Reading edition
On the Asiatic side the valley of the Sakaria and a long fault revealed by the line of lakes east of the Marmora provide ready-made frontiers which could be conveniently extended to the Gulf of Adramyt on the Ægean. This line constituted the Asiatic boundary of the Latin Empire of Constantinople in the period intervening between the years 1204 and 1261.
