Few of the more distinguished Italian men of letters have been able to keep themselves clear of public employment. Dante’s wealth and social eminence in the days of his prosperity did not allow him to decline the invidious office of Prior, to which he was raised in 1300. It was only tenable for two months, but this was long enough for his ruin. Florence was then rent by dissensions between two factions, the Whites and Blacks. The Government, by Dante’s courageous and probably wise advice, resolved to banish the leaders of both. As the chiefs of the Guelfic Blacks were Dante’s own connections, the Donati, while the Ghibelline Whites included Guido Cavalcanti, his most intimate friend, his counsel must have been patriotic and disinterested. Unfortunately, it was not unflinchingly carried out, some of the Whites being shortly afterwards allowed to return. Pope Boniface VIII., fearing that the Ghibelline or Imperialist party would thus obtain the upper hand in the city, incited Charles de Valois, brother of the French King, Philip the Fair, whom he had allured into Italy to attack the King of Naples, to make himself master of Florence. This he accomplished, and the consequent return of Dante’s adversaries led to the sacking of his house, the ruin of his fortune, and his life-long exile from his native city. He was at the time absent on an embassy at the Papal Court, from which he retired to Arezzo, where the other exiles had assembled, and must henceforth be reckoned among the Ghibellines.
