Fregoso

The Fregoso, also called Campofregoso, were a Genoese noble house of merchants from Val Polcevera, active in the city's politics from the thirteenth century. Thirteen Fregoso became doge, beginning with Domenico di Campofregoso, who deposed Gabriele Adorno on 13 August 1370 and held the longest consecutive dogeship of the republic.

Paolo di Campofregoso, archbishop of Genoa and a cardinal, seized the dogeship three times from 1462 amid violent feuds with his own kin. Ottaviano Fregoso, raised at the humanist court of Urbino and portrayed in Castiglione's The Book of the Courtier, was the last Fregoso doge; captured by the Spaniards, he died in the prison of Ischia in 1524.

In Andrea Doria's reform of 1528 the house was merged into the alberghi of De Fornari and De Ferrari. Although it revived its name in 1576, it never regained political importance.
