Born in the first half of the 14th century in Epirus to Pietro Bua Shpata the lord of Angelokastron and Delvina (1354).
[2] Shortly before Gjin Bua Shpata died on 29 October (1399, according to Nicol;[3] 1400 according to others), he appointed his brother, Skurra, ruler of Naupactus, as his successor as the despot of Arta.
[4] While Skurra fled to Angelokastron, a short time after, possibly as early as December 1399 (or by the end of 1401[5]), Muriq Shpata, his grandnephew, managed to evict Vonko from Arta and took over the governance of the city himself, while Skurra thus took over governance of Angelokastron.
The attack, under Carlo's general Galasso Peccatore, was repulsed, but Skurra died soon after, from wounds suffered in the war,[7] leaving his possessions to his son Pal Shpata.
[8] Skurra was succeeded by his son Pal, who became an Ottoman vassal and was aided with a contingent that was defeated by Tocco in 1406, after the latter had turned on the offensive, Angelokastron was ceded to the Turks and Pal retired to Naupaktos, however he sold it in 1407 to the Republic of Venice.
