What is the Balkan region?

The Balkan region is the area between the Black Sea and the Adriatic Sea. It is also called the Balkan Peninsula. It consists of a large variety of peoples speaking a wide group of languages and practicing several different religions. There are the Greeks speaking ancient Greek. The Romanians speak a language similar to Italian. The Serbians speak a Slavic language similar to Russian. The Hungarians speak a language similar to Mongolian. And the Albanians speak a Germanic language.
That area constantly divides into smaller and smaller nations making it easy for a large foreign empire to conquer them. That is called Balkanizing.
