Writing: Dracula

Is this a real, true story? Or part of it? Which elements are real and which fiction?

Dracula is not a real story, but part of it is. The author, Bram Stoker, inspired the character of Count Dracula in a prince who lived at that time in Transylvania, called Dracula. A lot of stories were told about Dracula and his cruelty to the people he killed. After his death, his tomb was opened and his body wasn’t found there. People believed that Dracula was not dead.
Another fictitious thing based in the truth is the existence of Vampires. All the characteristics we learn throughout the story about vampires weren’t invented by the writer, they were believed at the time of the story by people in Transylvania. The three things that had to be done to destroy vampires, used in the story against the vampire of Lucy and against Dracula at the end, were believed too.
However, all the characters except Count Dracula and the entire story are fiction, invented and written by the author.
