Bornio Samaritani

Bornio Samaritani was a Bolognese politician and diplomat and a leader of the Scacchesi, the Guelph faction around the Pepoli. In 1306 he and the banker Romeo Pepoli led a piazza rising against the moderate Guelph government; it failed and Romeo was briefly imprisoned. In 1308 his sister married Romeo's son Taddeo.

The papal legate Bertrando del Poggetto denied the city self-government, and in December 1332 jailed Bornio, Taddeo and Brandelisio Gozzadini in the Castel Galliera; a popular revolt forced him to free them within hours. The legate was driven out in 1334.

In May 1336 Bornio sat with Taddeo and Brandelisio on the extraordinary balìa that governed the city, and Taddeo became lord of Bologna in 1337.
