Then the city, in 1416, submitted to Braccio da Montone, who raised it to unprecedented power and glory.

On his death it fell back into new discords, from which it was rescued again by the Baglioni in 1466, now finally successful in their prolonged warfare with the rival family of Oddi.

But they did not hold their despotism in tranquillity.
In 1500 one of the members of the house, Grifonetto degli Baglioni, conspired against his kinsmen and slew them in their palaces at night.
As told by Matarazzo, this tragedy offers an epitome of all that is most, brilliant and terrible in the domestic feuds of the Italian tyrants.[3] The vicissitudes of the Bentivogli at Bologna present another series of catastrophes, due less to their personal crimes than to the fury of the civil strife that raged around them.

Giovanni Bentivoglio began the dynasty in 1400.

The next year he was stabbed to death and pounded in a wine-vat by the infuriated populace, who thought he had betrayed their interests in battle.
