[Sidenote: Bourbon duplicity]
In Naples and Sicily the recent events in Spain and France exerted a powerful influence over the minds of the people. In southern Italy the secret society of the Carbonari had become a power in the land. The members of this society, after the manner of Freemasons, took their name and the symbolism of their rites from the calling of the charcoal burners. Since the revolt against Bourbon tyranny in 1799, the Carbonari had played their part as revolutionary conspirators. By the year 1820 it was believed that one person out of every twenty-five in Naples belonged to the society. To offset their hidden power, the government encouraged the foundation of a rival society, known as the Calderari, or Braziers. This only made matters worse. After the success of the revolution in Spain, the head lodge of the Carbonari in Salerno issued orders for a rising in June. Later the date was postponed. A score of Carbonari serving in the ranks of a cavalry regiment at Nola, persuaded one of the officers, Lieutenant Morelli, to head a revolt in favor of a constitutional government. On July 2, Morelli marched out with a squadron of 150 men, and proclaimed for the Constitution. Only one trooper refused to follow his standard. The others rode along the road to Avellino and were received with enthusiasm all along the way. The country was ripe for revolt. At Avellino the commandant with all his garrison and the Bishop with the townspeople gave them a magnificent reception. The news of the revolt spread like wildfire throughout the kingdom of the Two Sicilies. Everywhere the Carbonari declared in its favor. Before the government had taken a single step, the Constitution was generally proclaimed and joyfully accepted by the populace. From Naples the King sent General Carrascosa to negotiate with the insurgents. In the meanwhile General Pepe, himself a Carbonaro of high rank, hastened to Avellino and placed himself at the head of the revolution. On July 6, the King published an edict promising a constitution within eight days, and then, feigning illness, committed the royal authority to his son, the Duke of Calabria. The Carbonari, recalling the fact that the King, in order to preserve his contingent rights to the Spanish crown, had but recently helped to sign the Spanish Constitution of 1812, insisted that this same Constitution should be proclaimed for Naples. Old King Ferdinand yielded and signed an edict to that effect. General Pepe and Morelli, at the head of the garrison of Avellino, and the national guards of Naples, triumphantly entered the city with public honors, and were received by the Duke of Calabria, in his capacity as viceroy. On July 13, the King in person swore to support the Constitution. Standing before the altar in the royal chapel, he raised his eyes to the crucifix and prayed that the vengeance of God might fall upon him if ever he broke his oath. Immediately afterward he wrote to the Emperors of Austria and Russia, declaring that his conduct on this occasion was a mere farce and that he regarded his obligations as null and void.
