Dissatisfied with the Pope's decision, Kaloyan sent a new letter to Rome, asking Innocent to send cardinals who could crown him emperor. He also informed the Pope that Emeric of Hungary had seized five Bulgarian bishoprics, asking Innocent to arbitrate in the dispute and determine the boundary between Bulgaria and Hungary. In the letter, he styled himself the "Emperor of the Bulgarians". The Pope did not accept Kaloyan's claim to an imperial crown, but dispatched Cardinal Leo Brancaleoni to Bulgaria in early 1204 to crown him king.
