24January 1458. He ordered the burghers of Sibiu to keep the peace with Vlad on 3March. Vlad styled himself "Lord and ruler over all of Wallachia, and the duchies of Amlaș and Făgăraș" on 20September 1459, showing that he had taken possession of both of these traditional Transylvanian fiefs of the rulers of Wallachia. Michael Szilágyi allowed the boyar Michael (an official of VladislavII of Wallachia) and other Wallachian boyars to settle in Transylvania in late March 1458. Before long, Vlad had the boyar Michael killed. In May, Vlad asked the burghers of Brașov to send craftsmen to Wallachia, but his relationship with the Saxons deteriorated before the end of the year. According to a scholarly theory, the conflict emerged after Vlad forbade the Saxons to enter Wallachia, forcing them to sell their goods to Wallachian merchants at compulsory border fairs. Vlad's protectionist tendencies or border fairs are not documented. Instead, in 1476, Vlad emphasized that he had always promoted free trade during his reign. The Saxons confiscated the steel that a Wallachian merchant had bought in Brașov without repaying the price to him. In response, Vlad "ransacked and tortured" some Saxon merchants, according to a letter that Basarab Laiotă (a son of DanII of Wallachia) wrote on 21January 1459. Basarab had settled in Sighișoara and laid claim to Wallachia. However, Matthias Corvinus supported DanIII (who was again in Brașov) against Vlad. DanIII stated that Vlad had Saxon merchants and their children impaled or burnt alive in Wallachia. Dan III broke into Wallachia, but Vlad defeated and executed him before 22April 1460. Vlad invaded southern Transylvania and destroyed the suburbs of Brașov, ordering the impalement of all men and women who had been captured. During the ensuing negotiations, Vlad demanded the expulsion or punishment of all Wallachian refugees from Brașov. Peace had been restored before 26July 1460, when Vlad addressed the burghers of Brașov as his "brothers and friends". Vlad invaded the region around Amlaș and Făgăraș on 24August to punish the local inhabitants who had supported DanIII. Ottoman war Konstantin Mihailović (who served as a janissary in the sultan's army) recorded that Vlad refused to pay homage to the sultan in an unspecified year. The Renaissance historian Giovanni Maria degli Angiolelli likewise wrote that Vlad had failed to pay tribute to the sultan for three years. Both records suggest that Vlad ignored the suzerainty of the Ottoman Sultan, Mehmed
