Pope Boniface quickly dismissed the other delegates and asked Dante alone to remain in Rome. At the same time (November 1, 1301), Charles of Valois entered Florence with the Black Guelphs, who in the next six days destroyed much of the city and killed many of their enemies. A new Black Guelph government was installed, and
Cante dei Gabrielli da
Gubbio was appointed of the city. In March 1302, Dante, a White Guelph by affiliation, along with the
Gherardini family, was condemned to exile for two years and ordered to pay a large fine. Dante was accused of corruption and financial wrongdoing by the Black Guelphs for the time that Dante was serving as city prior (Florence's highest position) for two months in 1300. The poet was still in Rome in 1302, as the Pope, who had backed the Black Guelphs, had "suggested" that Dante stay there. Florence under the Black Guelphs, therefore, considered Dante an absconder. Dante 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; if he had returned to Florence without paying the fine, he could have been burned at the stake. (In June 2008, nearly seven centuries after his death, the city council of Florence passed a motion rescinding Dante's sentence.) In 1306–07, Dante was a guest of in the region of
Lunigiana. Dante took part in several attempts by the White Guelphs to regain power, but these failed due to treachery. Bitter at the treatment he received from his enemies, he grew disgusted with the infighting and ineffectiveness of his former allies and vowed to become a party of one. He went to
Verona as a guest of
Bartolomeo I della Scala, then moved to
Sarzana in Liguria. Later he is supposed to have lived in
Lucca with a woman named Gentucca. She apparently made his stay comfortable (and he later gratefully mentioned her in
Purgatorio, XXIV, 37). Some speculative sources claim he visited Paris between 1308 and 1310, and other sources even less trustworthy say he went to
Oxford; these claims, first made in
Giovanni Boccaccio's book on Dante several decades after his death, seem inspired by readers who were impressed with the poet's wide learning and erudition. No longer occupied with the day-to-day affairs of Florentine politics after his exile, Dante deepened his engagement with philosophy and literature, as seen in the intellectual rigor and thematic scope of his prose works from this period. Yet, while his ideas traveled widely, there is no definitive evidence that he ever left Italy. Dante's to Henry VII of Luxembourg confirms his residence "beneath the springs of Arno, near Tuscany" in April 1311. In 1310, Holy Roman Emperor
Henry VII of
Luxembourg marched into Italy at the head of 5,000 troops. Dante saw in him a new
Charlemagne who would restore the office of the Holy Roman Emperor to its former glory and also retake Florence from the Black Guelphs. He wrote to Henry and several Italian princes, demanding that they destroy the Black Guelphs. Mixing religion and private concerns in his writings, he invoked the worst anger of God against his city and suggested several particular targets, who were also his personal enemies. It was during this time that he wrote , proposing a
universal monarchy under Henry VII. At some point during his exile, he conceived of the
Comedy, but the date is uncertain. The work is far more assured and ambitious than anything he had written in Florence. It is likely that he would have undertaken such a project only after accepting that his political ambitions, which had been central to him before his banishment, may have been indefinitely disrupted. It is also noticeable that Beatrice has returned to his imagination with renewed force and with a wider meaning than in the ; in (written –07) he had declared that the memory of this youthful romance belonged to the past. An early indication that the poem was underway is a notice by
Francesco da Barberino, tucked into his (
Lessons of Love), probably written in 1314 or early 1315. Francesco notes that Dante followed the
Aeneid in a poem called "Comedy" and that the setting of this poem (or part of it) was the underworld; i.e., hell. The brief note gives no incontestable indication that Barberino had read or even seen the
Inferno, or that this part had been published at the time, but it indicates composition was well underway and that the sketching of the poem might have begun some years before. (It has been suggested that a knowledge of Dante's work also underlies some of the illuminations in Francesco da Barberino's earlier
Officiolum [c. 1305–08], a manuscript that came to light in 2003.) It is known that the
Inferno had been published by 1317; this is established by quoted lines interspersed in the margins of contemporary dated records from
Bologna, but there is no certainty as to whether the three parts of the poem were each published in full or, rather, a few cantos at a time.
Paradiso was likely finished before he died, but it may have been published posthumously. In 1312, Henry assaulted Florence and defeated the Black Guelphs, but there is no evidence that Dante was involved. Some say he refused to participate in the attack on his city by a foreigner; others suggest that he had become unpopular with the White Guelphs, too, and that any trace of his passage had carefully been removed. Henry VII died (from a fever) in 1313 and with him any hope for Dante to see Florence again. He returned to Verona, where
Cangrande I della Scala allowed him to live in certain security and, presumably, in a fair degree of prosperity. Cangrande was admitted to Dante's Paradise (
Paradiso, XVII, 76). During the period of his exile, Dante corresponded with Dominican theologian Fr. Nicholas Brunacci (1240–1322), who had been a student of
Thomas Aquinas at the Santa Sabina
studium in Rome, later at Paris, and of
Albert the Great at the Cologne
studium. Brunacci became lector at the Santa Sabina
studium, forerunner of the
Pontifical University of Saint Thomas Aquinas, and later served in the
papal curia. In 1315, Florence was forced by
Uguccione della Faggiuola (the military officer controlling the town) to grant an amnesty to those in exile, including Dante. But for this, Florence required public penance in addition to payment of a high fine. Dante refused, preferring to remain in exile. When Uguccione defeated Florence, Dante's death sentence was commuted to house arrest, on condition that he go to Florence to swear he would never enter the town again. He refused to go, and his death sentence was confirmed and extended to his sons. Despite this, he still hoped late in life that he might be invited back to Florence on honorable terms, particularly in praise of his poetry. ==Death and burial==
