Guicciardini, it is well known, had governed Bologna and Romagna for the Medicean Popes.

He too was instrumental in placing Duke Cosimo at the head of the republic in 1536.
At Naples, in 1535, he pleaded the cause of Duke Alessandro against the exiles before Charles V.Nardi on this occasion acted as secretary and advocate for Filippo Strozzi and the exiles; his own history was composed in exile at Venice, where he died.

Segni was nephew of the Gonfalonier Capponi, and shared the anxieties of the moderate liberals during the siege of Florence.

Pitti was a member of the great house who contested the leadership of the republic with the Medici in the fifteenth century; his zeal for the popular party and his hatred of the Palleschi may still perhaps be tinctured with ancestral animosity.
Giannotti, in whose critique of the Florentine republic we trace a spirit no less democratic than Pitti's, was also an actor in the events of the siege, and afterwards appeared among the exiles.

In the attempt made by the Cardinal Salviati (1537) to reconcile Duke Cosimo and the adherents of Filippo Strozzi, Giannotti was chosen as the spokesman for the latter.
