The Republic of Macedonia occupies the western half of the ancient Kingdom of Macedonia. The part of the southern Balkan Peninsula traditionally known as Macedonia is bounded to the south by the Aegean Sea and the Aliákmon River; to the west by Lakes Prespa and Ohrid, the watershed west of the Crni Drim River, and the Sar Mountains; and to the north by the mountains of the Skopska Crna Gora and the watershed between the Morava and Vardar basins. The Pirin Mountains mark its eastern edge. Since 1913 this geographic and historical region has been divided between Greece, Serbia and Bulgaria, and only some 40 percent of its area is occupied by the independent state – REPUBLIC OF MACEDONIA.
