Paul of Segni was an Italian nobleman and Franciscan friar who served as the bishop of Tripoli in the Levant from 1261 until 1285 and as a papal legate to the kingdoms of Germany and Sicily in 1279–1280.
Paul was born into the Roman noble family of the counts of Segni and owned land in the Papal State.
[1] Opizo had excommunicated Bohemond VI, but Pope Urban IV granted Paul wide latitude in dealing with his nephew while the case was sub judice.
Since Bartholomew was also the vicar of the absentee patriarch of Antioch, Opizo dei Fieschi, this brought him into conflict with Paul.
By 1277, this had led to open warfare between the lord of Gibelet and the Templars on one side and Bohemond's government under Bartholomew and Sibyl on the other.
In a letter to Pope Nicholas III, Paul accused Bohemond of seizing his goods, imprisoning his servants and attacking his safehouse.
[1] In the fall of 1278, Roger of San Severino and Nicolas Lorgne arrived in Tripoli to mediate between the prince and the bishop.
Both Paul and Pope Nicholas had died by the time Bartholomew, belatedly obeying the summons, arrived in Rome in 1285.
