When Vlad II was called to a diplomatic meeting in 1442 with Sultan Murad II, he brought his young sons Vlad III and Radu along. But the meeting was actually a trap: All three were arrested and held hostage. The elder Vlad was released under the condition that he leave his sons behind.
"The sultan held Vlad and his brother as hostages to ensure that their father, Vlad II, behaved himself in the ongoing war between Turkey and Hungary," said Elizabeth Miller, a research historian and professor emeritus at Memorial University of Newfoundland in Canada.
Under the Ottomans, Vlad and his younger brother were tutored in science, philosophy and the arts. Vlad also became a skilled horseman and warrior, according to Radu Florescu and Raymond McNally, former professors of history at Boston College, who wrote several books about Vlad III — as well as his alleged connection to Stoker's Dracula — in the 1970s and 1980s.
"They were treated reasonably well by the current standards of the time," Miller said. "Still, [captivity] irked Vlad, whereas his brother sort of acquiesced and went over on the Turkish side. But Vlad held enmity, and I think it was one of his motivating factors for fighting the Turks: to get even with them for having held him captive.
