He was a knez and the head of Radinović-Pavlović noble family, a powerful magnate clan whose initially possessions spread from central to eastern Bosnia, gravitating around the Prača - Miljacka river axis, between the Krivaja Drina and the Upper Bosna rivers, with the seat in Borač and Pavlovac between Prača and Rogatica, and also held mines in Olovo and Fojnica.

The circumstances surrounding the assassination were recorded by Ivan Gundulić, Ragusan diplomat at the Bosnian court in Sutjeska, who was present on the scene to witness entire affair.

[7] When Stephen Dabiša (r. 1391–1395) died in September 1395, he had designated King Sigismund of Hungary, the husband of his cousin, Queen Mary, as his successor.

In foreign politics, he, as the other magnates of the Kingdom of Bosnia, supported Ladislaus of Naples in his struggle to wrestle the crown of Hungary from Sigismund of Luxemburg.

A plot to assassinate Pavle played out during the King Ostoja's 2nd reign, and the best source for the circumstances surrounding the event is a letter written by Ivan Gundulić, Ragusan diplomatic representative who was in Sutjeska in August 1415, where he attended a meeting of Bosnian noblemen at the stanak.

[13] A conspiracy against Pavle must have been hatched in the background of the stanak, held in Sutjeska in August 1415 and attended by all the major noblemen except for Hrvoje Vukčić.

During a walk, at the location called Parena Poljana, somewhere in the canyon of Bukovica between the royal court and the city-fortress Bobovac, a brawl erupted when Sandalj suddenly drew his sword, which was a cue to King Ostoja, who jumped on Pavle's son Petar and bound him, and Vukmir Zlatonosović, who immediately attacked Pavle who tried to escape but was caught by Sandalj's men, led by his brother, Vuk Hranić, and decapitated on site.

Vuk Hranić tied up Pavle's protovestijar, Brailo Tezalović, while a merchant from Prača, Pribislav Muržić, was captured by other Sandalj's men.

Pavle's lands were promptly divided between the conspirators,[13][2] but Petar and his brother Knez Radosav Pavlović will successfully repel all attempts of takeover from happening.

This means that Tvrtko II, who was pro-Ottman, had the support of Pavlović's However, there were other reasons to account for, such as Pavle's politics toward Konavle which differed from Sandalj's significantly.
