After some time, in imitation of Rienzi, Francesco Baroncegli seized upon the tribunate of Rome, and expelled the senators; and the pope, as the most effectual means of repressing him, drew Niccolo from his prison, sent him to Rome, and restored to him the office of tribune; so that he reoccupied the state and put Francesco to death; but the Colonnesi becoming his enemies, he too, after a short time, shared the same fate, and the senators were again restored to their office.

The king of Hungary, having driven out Queen Joan, returned to his kingdom; but the pope, who chose to have the queen in the neighborhood of Rome rather than the king, effected her restoration to the sovereignty, on the condition that her husband, contenting himself with the title of prince of Tarento, should not be called king.

Being the year 1350, the pope thought that the jubilee, appointed by Boniface VIII.

to take place at the conclusion of each century, might be renewed at the end of each fifty years; and having issued a decree for the establishment of it, the Romans, in acknowledgment of the benefit, consented that he should send four cardinals to reform the government of the city, and appoint senators according to his own pleasure.

The pope again declared Louis of Tarento, king, and in gratitude for the benefit, Queen Joan gave Avignon, her inheritance, to the church.
