Balkans

The Balkans is a peninsula, or group of countries, in Europe. The region has a combined area of 550,000 km2 and an approximate population of 55 million people. The region takes its name from the Balkan Mountains, which run through the centre of Bulgaria into eastern Serbia and then continue to Slovenia as the Dinaric Alps.
Definitions and boundaries
Name
Balkans comes from the Turkish language meaning "chain of wooded mountains" or 'swampy forest'.
Geography
The Balkans are bordered by water on three sides: the Black Sea to the east and branches of the Mediterranean Sea to the south and west (including the Adriatic, Ionian, Aegean and Marmara seas). The Balkan Peninsula is bordered on the north by the Danube, Sava, and Krca rivers.
History
Shortly before the medieval period in the 5th and 6th centuries, the Balkans were invaded by the Romans. The Romans were said not to be like other conquerors. They were said to be very powerful and robust. They won and spread the Roman culture through the Balkan peninsula. The Balkan peninsula was completely under Roman control by 1000 CE.
