Vlad the Impaler - Hero or Villain

He was the second son of Vlad Dracul, who became the ruler of Wallachia in 1436. Vlad and his younger brother, Radu, were held as hostages in the Ottoman Empire in 1442 to secure their father's loyalty. Vlad's eldest brother Mircea and their father were murdered after John Hunyadi, regent-governor of Hungary, invaded Wallachia in 1447. Hunyadi installed Vlad's second cousin, Vladislav II, as the new voivode. Hunyadi launched a military campaign against the Ottomans in the autumn of 1448, and Vladislav accompanied him. Vlad broke into Wallachia with Ottoman support in October, but Vladislav returned, and Vlad sought refuge in the Ottoman Empire before the end of the year. Vlad went to Moldavia in 1449 or 1450 and later to Hungary.
Relations between Hungary and Vladislav later deteriorated, and in 1456 Vlad invaded Wallachia with Hungarian support. Vladislav died fighting against him. Vlad began a purge among the Wallachian boyars to strengthen his position. He came into conflict with the Transylvanian Saxons, who supported his opponents, Dan and Basarab Laiotă (who were Vladislav's brothers), and Vlad's illegitimate half-brother, Vlad Călugărul. Vlad plundered the Saxon villages, taking the captured people to Wallachia, where he had them impaled (which inspired his cognomen). Peace was restored in 1460.
