Count Cilli, however, an ambitious and able man, soon gained almost unlimited control over the mind of his young ward, and became so arrogant and dictatorial, filling every important office with his own especial friends, and removing those who displeased him, that general discontent was excited and conspiracy was formed against him.

Cilli was driven from Vienna with insults and threats, and the conspirators placed the regency in the hands of a select number of their adherents.
While affairs were in this condition, John Hunniades, as regent, was administering the government of Hungary with great vigor and sagacity.
He was acquiring so much renown that Count Cilli regarded him with a very jealous eye, and excited the suspicions of the young king that Hunniades was seeking for himself the sovereignty of Hungary.

Cilli endeavored to lure Hunniades to Vienna, that he might seize his person, but the sagacious warrior was too wily to be thus entrapped.
The Turks were now in the full tide of victory.

They had conquered Constantinople, fortified both sides of the Bosporus and the Hellespont, overrun Greece and planted themselves firmly and impregnably on the shores of Europe.
