of Naples died, and was succeeded by his son Robert.

Henry of Luxemburg had been elected to the empire, and came to Rome for his coronation, although the pope was not there.

His coming occasioned great excitement in Lombardy; for he sent all the banished to their homes, whether they were Guelphs or Ghibellines; and in consequence of this, one faction endeavoring to drive out the other, the whole province was filled with war; nor could the emperor with all his endeavors abate its fury.

Leaving Lombardy by way of Genoa, he came to Pisa, where he endeavored to take Tuscany from King Robert; but not being successful, he went to Rome, where he remained only a few days, being driven away by the Orsini with the consent of King Robert, and returned to Pisa; and that he might more securely make war upon Tuscany, and wrest the country from the hands of the king, he caused it to be assailed by Frederick, monarch of Sicily.
