On October 6, 1306, Dante, expelled from Bologna, had concluded peace at Sarzana between Marchese Franceschino Malaspina and the Bishop of Luni. In 1308 he was probably in Lucca, where the presence in that year of his eldest son, Giovanni, is confirmed by a reference to Gentucca, a girl of Lucca, in Purgatory, XXIV, the second part of the Divine Comedy. Having returned to the Casentino (the country north of Arezzo), he sent shortly afterward to Moroello Malaspina, a Guelf leader, the canzone "Love, Since After All I Am Forced to Grieve" with an explanatory Epistle IV. He was probably in the Casentino when he learned of the election of Henry of Luxembourg as German king (1308). In exile he had long meditated the events that had overtaken him and had become convinced that those events and the ensuing disorder had occurred only because there was no Holy Roman emperor. The heart of the exile exulted, therefore, while the deliverer prepared to come to Italy. And when Clement V agreed to crown the new emperor in Rome, the poet made himself the sounding board of the general expectation and delight, in Epistle V ("Universìs et singulìs," 1310). Only Florence, allied to Robert of Naples, opposed the emperor; and the poet expressed his indignation in Epistle VI (March 31, 1311). He then turned to Henry, to whom homage had already been paid in Milan (Epistle VII, April 17, 1311). For this plea, Dante was excluded from an amnesty granted by Florence to other exiles on September 2, 1311, as Henry was approaching the city to besiege it. Out of reverence for his native city, which he described in Paradise as an "evil stepmother," he did not appear among the exiles who encamped with the imperial troops on the plain of San Salvi, and his name is missing from a list of the condemned published by the commune in March 1313. In the years immediately following the arrival of Henry VII in Italy, Dante composed the Monarchia, a treatise of political philosophy. A rift that soon opened between Henry and Clement V and the sudden death of the Emperor dashed the poet's hopes; after staying for some time in Tuscany he returned about 1316 to Verona, where Cangrande della Scala (imperial vicar nominated by Henry VII in 1312) was founding a powerful Ghibelline state in northern Italy.
