The Priciplality of Wallachia: The Princedom of Dracula

As you can see on the map above, this is the general area of the principality of Wallachia, whose long history is linked with that of Transylvania and Modolva, and Hungary. 

During the Turkish wars, it was used by the Hungarian army and the Transylvanian armies as means to get to the armies, and fight over land.  This is also the land where the famous Vlad Tepes was rules, along with his father and brothers.

This was the land that was destined to be one of two Principlalities to form the Princedom and future Kingdom of Romania.  (Transylvania would join in 1919)
