Francis II of the Two Sicilies in exile by making new grants in the same name. Those nobles who maintained allegiance to the pope became known as the Black Nobility. After the unification of Italy, its kings continued to create titles of nobility for eminent Italians, this time valid for all Italian territory. For example, General Enrico Cialdini was created Duca di Gaeta for his role during unification. The practice continued until the 20th century, when nominations would be made by the Prime Minister of Italy and approved by the Crown. In the aftermath of the First World War, most Italians who were ennobled received their titles through the patronage of the Mussolini government. Examples include General Armando Diaz (Duca della Vittoria), Admiral Paolo Thaon di Revel (Duca del Mare), Commodore Luigi Rizzo (Conte di Grado e di Premuda), Costanzo Ciano (Conte di Cortellazzo i Buccari), Dino Grandi (Conte di Mordano) and Cesare Maria de Vecchi (Conte di Val Cismon). Many of these were victory titles for services rendered to the nation in the Great War. The writer and aviator Gabriele d'Annunzio was created Principe di Montenevoso in 1924, and the physicist, inventor, and Nobel laureate Guglielmo Marconi was also ennobled in 1924 as Marchese Marconi. In 1937, Ettore Tolomei was ennobled as Conte della Vetta. When Cardinal Eugenio Pacelli became Pope in 1939, Mussolini had the title of Principe posthumously bestowed on the new Pontiff's brother Francesco Pacelli, who had already been made a Marchese by the Holy See during his lifetime. In 1929, the Lateran Treaty acknowledged all Papal titles created before that date and undertook to give unquestioned recognition to titles conferred by the Holy See on Italian citizens in the future. After the successful Italian invasion of Abyssinia, the Mussolini government recommended some Italians to the king of Italy for titles of nobility. For example, Marshal Pietro Badoglio was created Marchese del Sabotino and later Duke of Addis Abeba, while General Rodolfo Graziani became Marchese di Neghelli. Italian Republic In 1946, the Kingdom of Italy was replaced by a republic. Under the Italian Constitution adopted in 1948, titles of nobility, although still used as a courtesy, are not legally recognised. Certain predicati (territorial designations) recognised before 1922 may continue to be attached to surnames and used in legal documents. Often these were historic feudal territories of noble families. Although a high court ruling in 1967 definitively
