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. [Sidenote: Revolution in Portugal] [Sidenote: End of Lisbon regency] The contagion of Spain and Sicily proved too much for the people of Portugal. The continued absence of the royal family in Brazil, and the unwelcome prolongation of the British regency had long caused dissatisfaction in Portugal.

The officers of the army, the magistrates, the priests and townspeople united in declaring against the regency. They established a provisional Junta to govern in the name of the King until the Cortes of Portugal could be convened to frame a constitution. The authority of the regency in Oporto was lost without a blow. The Junta immediately seized the reins of government, and began its career by dismissing all English officers and paying the arrears of the soldiers. In Lisbon the regency itself tried to stem the storm by giving its formal approval to the measures of the Junta of Oporto. The troops of Lisbon, however, would no longer recognize the authority of the government. Within a fortnight the regency was deposed, and a Junta installed in its place. Beresford was forbidden to return to Portugal. He went to England, but found there that the British Ministry did not deem it advisable to
