After
Vlad cel Tânăr, gained support for his claim on the throne of
Wallachia from the Ottomans with the help of the
Craiovești family, Mihnea cel Rău ceded the throne to his son, Mircea, on 12 October 1509. Although in the older Romanian historiography it was thought that Mircea only co-ruled with his father, this was proven false by the documents he issued. The first documents issued by Mircea were recorded from 29 October, signed with "
Io Mircea voievod, din mila lui Dumnezeu, domn" ("
Io Mircea voivode, by God's mercy, lord"). Due to his anti-Ottoman views,
Emperor Maximilian I sent him a gift in the form of a
mail cap and shirt covered with
gold cloth and
velvet, and decorated with several
sapphires and
garnets, in the hopes of securing an alliance with "the Great Wallachian", as he referred to Mircea. Mircea left Wallachia around 26 January 1510, after a battle near
Cotmeana with an
Ottoman army led by
Neagoe, the former
great postelnic. Mircea eventually met with his father in
Sibiu. Together with his soldiers, he accompanied the
Voivode of Transylvania to
Slimnic on 11 March. Following the assassination of his father, he took part in catching the assassins. Mircea himself managed to kill one of the assassins, Danciu Țepeluș, a son of
Basarab Țepeluș. ==Attempts to retake the throne==
