Branca Doria

Branca Doria (c. 1233–1325) was a Genoese patrician with lands and offices in Sardinian Logudoro. By marrying Caterina, daughter of Michele Zanche, governor of Logudoro, he claimed the region, and around 1275 he had his father-in-law murdered at a banquet in the Nurra and seized his power.

Dante places his soul in Hell while still alive, in the Ptolomaea of Inferno Canto XXXIII, for betraying a guest. When the Ghibellines were expelled from Genoa in 1317 he directed his politics from Savona, and he may have been killed in Sardinia in 1325 as Aragonese power grew.
