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 Madame Gentucca. Some not sure sources say that he was also in Paris between 1308 and 1310. In 1310, the Holy Roman Emperor Henry VII of Luxembourg, marched 5,000 troops into Italy. Dante saw in him a new Charlemagne who would restore the office of the Holy Roman Emperor for re-take 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, he invoked the worst anger of God against his city, suggesting several particular targets that coincided with his personal enemies. It was during this time that he wrote the first two books of the "Divine Comedy".
