[3] During the reign of Andrew II, he was a faithful supporter of crown prince Béla, who held the title of Duke of Transylvania after 1226, following the agreement between the king and his son after a series of conflicts for the throne.
Sometime Duke Béla acted independently of his father, as it is demonstrated by his grant of tax exemption to Transylvanian knights in 1231 and by his donation of lands situated in Wallachia in 1233.
[2] According to László Markó, he held the office between 1226 and 1229, however existing charters only prove the term of voivodeship in 1227.
[7] When Béla ascended the throne in 1235, Pousa was appointed voivode of Transylvania for the second time.
Voivode Pousa fought them with his royal army near Burzenland (Hungarian: Barcaság), where he fell in battle on 31 March 1241.
