Vlad Tepes

Vlad III Dracula, also known as Vlad III the Impaler, was a Voievod of Wallachia, ruling between 1456 - 1462.

Historically
In 1462, Mehmed II was driven back by Vlad III Dracula near Bucharest. However, the latter was betrayed imprisoned by the Hungarian king Matthias Corvinus. This caused outrage among many influential Hungarian figures and Western admirers of Vlad's success in the battle against the Ottoman Empire (and his early recognition of the threat it posed), including high-ranking members of the Vatican and the remenants of the Byzantine nobility. Because of this, Matthias granted him the status of distinguished prisoner. Eventually, Dracula was freed in late 1475 and was sent with an army of Hungarian and Serbian soldiers to recover Bosnia from the Ottomans. He defeated Ottoman Forces and he gained his first victory against the Ottoman Empire. Upon this victory, Ottoman Forces entered Bucharest in 1476 under the command of Mehmed II. During a fierce battle, Vlad was killed and, according to some sources, his head and ceremonial dagger were sent to Constantinople to discourage the other rebellions.

In 1511, the Assassin Ezio Auditore da Firenze went on a quest to find his sword hidden in his prison in Constantinople, which was rumored to be a weapon that could defeat any foe.
