Frederic, however, the faithful guardian of the young prince, was devoting the utmost care to his education, and refused to accede to the urgent and reiterated requests to send the young monarch to his realms. When Ladislaus was about ten years of age the Emperor Frederic visited the pope at Rome, and took Ladislaus in his glittering suite. The precocious child here astonished the learned men of the court, by delivering an oration in Latin before the consistory, and by giving many other indications of originality and vigor of mind far above his years. The pope became much attached to the youthful sovereign of three such important realms, and as Frederic was about to visit Naples, Ladislaus remained a guest in the imperial palace. Deputies from the three nations repaired to Rome to urge the pope to restore to them their young sovereign. Failing in this, they endeavored to induce Ladislaus to escape with them. This plan also was discovered and foiled. The nobles were much irritated by these disappointments, and they resolved to rescue him by force of arms. All over Hungary, Bohemia and Austria there was a general rising of the nobles, nationalities being merged in the common cause, and all hearts united and throbbing with a common desire. An army of sixteen thousand men was raised. Frederic, alarmed by these formidable preparations for war, surrendered Ladislaus and he was conveyed in triumph to Vienna. A numerous assemblage of the nobles of the three nations was convened, and it was settled that the young king, during his minority, should remain at Vienna, under the care of his maternal uncle, Count Cilli, who, in the meantime, was to administer the government of Austria. George Podiebrad was intrusted with the regency of Bohemia; and John Hunniades was appointed regent of Hungary. Ladislaus was now thirteen years of age. The most learned men of the age were appointed as his teachers, and he pursued his studies with great vigor. 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.
