When he grew up, he became a Guelph, because his father had been one before him, just as an American boy might become a Democrat or a Republican, simply because his father had happened to be a Democrat or a Republican. But after a few years, Dante saw that Italy, unless united under a single head, threatened to perish as a victim of the disordered jealousies of a thousand little cities. Then he became a Ghilbeiline.
He looked for help beyond the Alps. He hoped that a mighty emperor might come and re-establish unity and order. Alas! he hoped in vain. The Ghibellines were driven out of Florence in the year 1802. From that time on until the day of his death amidst the dreary ruins of Ravenna, in the year 1321, Dante was a homeless wanderer, eating the bread of charity at the table of rich patrons whose names would have sunk into the deepest pit of oblivion but for this single fact, that they had been kind to a poet in his misery. During the many years of exile, Dante felt compelled to justify himself and his actions when he had been a political leader in his home-town, and when he had spent his days walking along the banks of the Arno that he might catch a glimpse of the lovely Beatrice Portinari, who died the wife of another man, a dozen years before the Ghibelline disaster.
