throne of Naples and the island of Sicily (where the constitution of 1812 virtually had disempowered him) was returned to him. In 1816 he annulled the constitution and Sicily became fully reintegrated into the new state, which was now officially called the Regno delle Due Sicilie (Kingdom of Two Sicilies). Ferdinand IV became Ferdinand I. A number of accomplishments under the administration of Kings Joseph and Joachim Murat, such as the Code Civil, the penal and commercial code, were kept (and extended to Sicily). In the mainland parts of the Kingdom, the power and influence of both nobility and clergy had been greatly reduced, though at the expense of law and order. Brigandage and the forceful occupation of lands were problems the restored Kingdom inherited from its predecessors. The Vienna Congress had granted Austria the right to station troops in the kingdom, and Austria, as well as Russia and Prussia, insisted that no written constitution was to be granted to the kingdom. In October 1815, Joachim Murat landed in Calabria, in an attempt to regain his kingdom. The government responded to acts of collaboration or of terrorism with severe repression and by June 1816 Murat's attempt had failed and the situation was under government control. However, the Neapolitan administration had changed from conciliatory to reactionary policies. The French novelist Henri de Stendhal, who visited Naples in 1817, called the kingdom "an absurd monarchy in the style of Philip II". As open political activity was suppressed, liberals organized themselves in secret societies, such as the Carbonari, an organization whose origins date back into the French period and which had been outlawed in 1816. In 1820 a revolution planned by Carbonari and their supporters, aimed at obtaining a written constitution (the Spanish constitution of 1812), did not work out as planned. Nevertheless, King Ferdinand felt compelled to grant the constitution sought by the liberals (13 July). That same month, a revolution broke out in Palermo, Sicily, but was quickly suppressed. Rebels from Naples occupied Benevento and Pontecorvo, two enclaves belonging to the Papal States. At the Congress of Troppau (Nov. 19th), the Holy Alliance (Metternich being the driving force) decided to intervene. On 23 February 1821, in front of 50,000 Austrian troops paraded outside his capital, King Ferdinand cancelled the constitution.
