The Balkans (/ˈbɔːlkənz/ BAWL-kənz), also known as the Balkan Peninsula, is a geographic area in Southeast Europe with various geographical and historical definitions.[1][2][3] The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish Straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined.[4] The highest point of the Balkans is Mount Musala, 2,925 metres (9,596 ft), in the Rila mountain range, Bulgaria.
The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808,[5] who mistakenly considered the Balkan Mountains the dominant mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. The term Balkan Peninsula was a synonym for Rumelia in the 19th century, the European provinces of the Ottoman Empire. It had a geopolitical rather than a geographical definition, which was further promoted during the creation of the Kingdom of Yugoslavia in the early 20th century. The definition of the Balkan Peninsula's natural borders does not coincide with the technical definition of a peninsula; hence modern geographers reject the idea of a Balkan peninsula, while historical scholars usually discuss the Balkans as a region. The term has acquired a stigmatized and pejorative meaning related to the process of Balkanization,[4][6] and hence the preferred alternative term used for the region is Southeast Europe.
The origin of the word Balkan is obscure; it may be related to Persian bālk 'mud', and the Turkish suffix an 'swampy forest'[7] or Persian balā-khāna 'big high house'.[8] Related words are also found in Turkic languages.[9] It was used mainly during the time of the Ottoman Empire. In modern Turkish balkan means 'chain of wooded mountains'.[10][11]
From classical antiquity through the Middle Ages, the Balkan Mountains were called by the local Thracian[12] name Haemus.[13] According to Greek mythology, the Thracian king Haemus was turned into a mountain by Zeus as a punishment and the mountain has remained with his name. A reverse name scheme has also been suggested. D. Dechev considers that Haemus (Αἷμος) is derived from a Thracian word *saimon, 'mountain ridge'.[14] A third possibility is that "Haemus" (Αἵμος) derives from the Greek word "haima" (αἷμα) meaning 'blood'. The myth relates to a fight between Zeus and the monster/titan Typhon. Zeus injured Typhon with a thunder bolt and Typhon's blood fell on the mountains, from which they got their name.[15]
