Boniface quickly sent away the other representatives and asked Dante alone to remain in Rome. At the same time (November 1, 1301), Charles de Valois was entering Florence with Black Guelphs, who in the next six days destroyed much of the city and killed many of their enemies. A new government was installed of Black Guelphs, and Messer Cante dei Gabrielli di Gubbio was appointed PodestĂ of Florence. Dante was condemned to exile for two years, and to pay a large fine. The poet was still in Rome, where the Pope had "suggested" he stay, and was therefore considered an absconder. He did not pay the fine, in part because he believed he was not guilty, and in part because all his assets in Florence had been seized by the Black Guelphs. He was condemned to perpetual exile, and if he returned to Florence without paying the fine, he could be burned at the stake.
The poet took part in several attempts by the White Guelphs to regain the power they had lost, but these failed due to treachery. Dante, bitter at the treatment he had received at the hands of his enemies, also grew disgusted with the infighting and ineffectiveness of his erstwhile allies, and vowed to become a party of one. At this point, he began sketching the foundations for the Divine Comedy, a work in 100 cantos, divided into three books of thirty-three cantos each, with a single introductory canto.
He went to Verona as a guest of Bartolomeo della Scala, then moved to Sarzana (Liguria). After this, he is supposed to have lived for some time in Lucca with Madame Gentucca, who made his stay comfortable (and was later gratefully mentioned in Purgatorio, XXIV, 37). Some speculative sources say that he was also in Paris between 1308 and 1310. Other sources, even less trustworthy, take him to Oxford.
In 1310 Henry VII of Luxembourg, King of the Romans (Germany), marched with 5,000 troops into Italy. Dante saw in him a new Charlemagne who would restore the former glory of the office of the Holy Roman Emperor, and also re-take Florence from the Black Guelphs; he wrote to him and to several Italian princes public letters inciting them to destroy the Black Guelphs. Mixing religion and private concerns, he invoked the worst anger of God against his town, suggesting several particular targets that coincided with his personal enemies. It was during this period that he wrote the first two books of the Divine Comedy.
In Florence, Baldo d'Aguglione pardoned most of the White Guelphs in exile and allowed them to come back; however, Dante had gone beyond the pale in his violent letters to Arrigo (Henry VII), and he was not recalled.
In 1312, Henry VII assaulted Florence and defeated the Black Guelphs, but there is no evidence that Dante was involved. Some say he refused to participate in the assault on his city by a foreigner; others suggest that his name had become unpleasant for White Guelphs too and that any trace of his passage had carefully been removed. In 1313 Henry VII died, and with him any residual hope for Dante to see Florence again. He returned to Verona, where Cangrande I della Scala allowed him to live in a certain security and, presumably, in a fair amount of prosperity. Cangrande was admitted to Dante's Paradise (Paradiso, XVII, 76).

In 1315, Florence was forced by Uguccione della Faggiuola (the military officer controlling the town) to grant an amnesty to people in exile. Dante too was in the list of citizens to be pardoned. But Florence required that, apart from paying a sum of money, these citizens agreed to be treated as public offenders in a religious ceremony. Dante refused this outrageous formula, preferring to remain in exile.
When Uguccione finally defeated Florence, Dante's death sentence was converted into confinement, at the sole condition that he go to Florence to swear that he would never enter the town again. Dante didn't go. His condemnation to death was confirmed and extended to his sons.
Dante still hoped late in life that he might be invited back to Florence on honourable terms. For Dante, exile was nearly a form of death, stripping him of much of his identity. He addresses the pain of exile in Paradiso, XVII (55-60), where Cacciaguida, his great-great-grandfather, warns him what to expect:
| | ". . . You shall leave everything you love most: |
| | this is the arrow that the bow of exile |
| | shoots first. You are to know the bitter taste |
| | of others' bread, how salty it is, and know |
| | how hard a path it is for one who goes |
| | ascending and descending others' stairs . . ." |
As for the hope of returning to Florence, he describes it wistfully, as if he had already accepted its impossibility, (Paradiso, XXV, 1–9):
| | If it ever come to pass that the sacred poem |
| | to which both heaven and earth have set their hand |
| | so as to have made me lean for many years |
| | should overcome the cruelty that bars me |
| | from the fair sheepfold where I slept as a lamb, |
| | an enemy to the wolves that make war on it, |
| | with another voice now and other fleece |
| | I shall return a poet and at the font |
| | of my baptism take the laurel crown... |
His 1780 tomb in Ravenna.
Of course it never happened. Prince Guido Novello da Polenta invited him to Ravenna in 1318, and he accepted. He finished Paradiso, and died in 1321 (at the age of 56) while on the way back to Ravenna from a diplomatic mission in Venice, perhaps of malaria contracted there. Dante was buried in Ravenna at the Church of San Pier Maggiore (later called San Francesco). Bernardo Bembo, praetor of Venice in 1483, took care of his remains by organizing a better tomb.
On the grave, some verses of Bernardo Canaccio, a friend of Dante, dedicated to Florence:
parvi Florentia mater amoris
"Florence, mother of little love"
Eventually, Florence came to regret Dante's exile, and made repeated demands for the return of his remains. The custodians of the body at Ravenna refused to comply, at one point going so far as to conceal the bones in a false wall of the monastery. Nevertheless, in 1829, a tomb was built for him in Florence in the basilica of Santa Croce. That tomb has been empty ever since, with Dante's body still remaining in its tomb in Ravenna, far from the land he loved so dearly. The front of his tomb in Florence reads Onorate l'altissimo poeta - which roughly translates as Honour the most exalted poet.
Recently, a recreation of Dante's face was made, showing that his features were much more ordinary than once thought.
