Well now, about Dracula (excuse me, I meant Vlad the Impaler)... You might be surprised to find out that many of my co-nationals think of him as a great national hero, but that's partly because of the way history used to be taught during the Communist era, when most of our "good"/famous past rulers were portrayed almost like communist precursors (which was supposed to be a great "honor" for them). I could have never imagined the man's international post-communist career as "Dracula".
Personally, I'm no expert in Vlad Tepes, and I have no intention to feed you with stuff that you can find on Wikipedia yourselves.
I'd only say that, the way I see, he was indeed a rough and bold warrior, expert in guerrilla tactics, who was once able to disseminate panic and produce heavy casualties to an invading Turkish army in a night attack, with just a handful of people on his side (he spoke perfect Turkish). In all odds, he was a just (though cruel) man, who hated injustice and reserved his famous punishment method only for criminals and invaders (not that I'm in approval of his style ). Of course, one could not expect to survive for long by defying the mighty Ottoman Empire like that. Those were the times. And if you guys ever get the chance to go through Transylvania, you should stop by the city of Sighisoara (Vlad's birthplace), it's a beautiful place and region, and it's worth paying a visit to the fortress and the surroundings.
I'm not sure if I was able to be of much help with this, fact is that Middle Ages history is not exactly my field. Still, should you have more questions, feel free to ask.
