The emperor, in his vexation, foolishly sent an army of five thousand men into Hungary, insanely hoping to take the crown by force of arms, but he was soon compelled to relinquish the hopeless enterprise.

The capital was divided into hostile factions, and the whole country was ravaged by the sweep of armies.
