[1] He contributed to the Antologia, a celebrated Florentine review, and in 1847 founded a newspaper called L'Italia, the programme of which was "Reform and Nationality".
In 1848, Montanelli served with the Tuscan student volunteers at the battle of Curtatone, where he was wounded and taken prisoner by the Austrians.
[2] After being liberated, Montanelli returned to Tuscany, and the grand duke Leopold II, knowing that he was popular with the masses, sent him to Livorno to quell the disturbances.
But Leopold, alarmed at the turn affairs were taking, fled from Florence, and Montanelli, Guerrazzi and Mazzini were elected "triumvirs" of Tuscany.
[2] After the restoration of the grand duke, Montanelli, who was in exile in Paris, was tried and condemned by default; he remained some years in France, where he became a partizan of Napoleon III.
