Gilbert, Count of Gravina

Gilbert was a Norman Count of Gravina from 1159 until 1167. His father Bertrand was the illegitimate son of Rotrou III, Count of Perche. He was a cousin of Margaret of Navarre, the queen of Sicily. He arrived in Sicily sometime around 1159 and, through Margaret's influence, was created Count of Gravina in Apulia immediately.

Late in that same year, Gilbert joined a conspiracy of nobles, including Richard of Aquila, Roger of Acerra, and Bohemond of Tarsia, Count of Manoppello. The conspiracy was of only minor lords, but it gained traction. The aim of the conspirators was to assassinate Maio of Bari and in this they succeeded on 10 November 1160. The rebellion which followed was short-lived in Sicily, and Gilbert was one of the barons restored to favour, along with Bohemond.

However, on the peninsula, the rebels, led by Andrew of Rupecanina, Robert of Loritello and Tancred of Lecce, marched on Butera and burned it. King William himself entered the field against Tancred, his nephew, while Gilbert held the Campania for him.

Gilbert took advantage of the death of William in 1166 to pressure his cousin, the regent, into giving him a high position at court. Gilbert became the personal enemy of Margaret's chief minister, the caïd Peter, and plotted his downfall and death. Peter fled Sicily and reconverted to Islam. However, Margaret still ignored her cousin and appointed one Richard of Mandra, who had saved her late husband's life, count of Molise and chancellor. Gilbert promptly turned on him and the two met for a duel, but were separated before combat could begin. At that point, to rid Palermo of him, Margaret sent Gilbert to the peninsula as catepan of Apulia and Campania to prepare for a possible invasion of Frederick Barbarossa.
