Brancaleone Doria

Brancaleone Doria (1337–1409), a Genoese Doria born illegitimate in Sardinia, was caught between Aragon and Arborea. In 1357 Peter IV of Aragon legitimised him and granted him his ancestral lands, including Castelgenovese and Monteleone. In 1376 he married Eleanor of Arborea, sister of Hugh III, in a political match.

After Hugh's murder in 1383, Eleanor ruled for their son Frederick, while Brancaleone went to Barcelona to negotiate peace, but was arrested and held at Cagliari until 1390.

Freed, he turned against Aragon: in 1391 he and his son Mariano took Sassari and Osilo, and in February 1392 announced that all territory held in 1388 was recovered. After Mariano died in 1407 he withdrew to Castelgenovese, where he was killed in 1409, before the Battle of Sanluri.
