Consolidation

The circumstances and the date of Vlad's return to Wallachia are uncertain. He invaded Wallachia with Hungarian support either in April, July or August 1456. Vladislav II died during the invasion. Vlad sent his first extant letter as voivode of Wallachia to the burghers of Brașov on 10 September. He promised to protect them in case of an Ottoman invasion of Transylvania, but he also sought their assistance if the Ottomans occupied Wallachia. In the same letter, he stated that "when a man or a prince is strong and powerful he can make peace as he wants to; but when he is weak, a stronger one will come and do what he wants to him", showing his authoritarian personality.

Multiple sources (including Laonikos Chalkokondyles 's chronicle) recorded that hundreds or thousands of people were executed at Vlad's order at the beginning of his reign. He began a purge against the boyars who had participated in the murder of his father and elder brother or whom he suspected of plotting against him. Chalkokondyles stated that Vlad "quickly effected a great change and utterly revolutionized the affairs of Wallachia" through granting the "money, property, and other goods" of his victims to his retainers. The lists of the members of the princely council during Vlad's reign also show that only two of them (Voico Dobrița and Iova) were able to retain their positions between 1457 and 1461.
