Where did vampires originated?

It originated in Transylvania, With Vlad Dracula. No I'm not talking about Bram Strokers Vampire, but Vlad the Impaler. He was a real life person born in the winter of 1431, in Transylvania. The reason why peole called him the Impaler is because if he captured war prisoners they would be put onto stakes and they would die from being impaled through the heart. He also would drink the blood of those people.
