Giorgio Carlo Calvi, Count of Bergolo (Athens, 15 March 1887 – Rome, 25 February 1977) was an Italian general during World War II and the husband of Princess Yolanda of Savoy, the eldest daughter of King Victor Emmanuel III.

He was born into a family of the Piedmontese nobility, as the eldest son and second child of Giorgio Lorenzo Calvi Conte di Bergolo (1852-1924) and his wife, Baroness Anna Guidobono-Cavalchini-Roero-San Severino (1862-1929).

[1] His elder sister, Matilda Emilia Francesca Maria Calvi dei conti di Bergolo (1885-1949) married Prince Aage of Denmark.

In June 1940, after Italy's entry into World War II, he was given command of the Libyan Cavalry Group; he was promoted to brigadier general on 1 October 1940, and in February 1941 he became chief of staff of the liaison office with Panzer Army Africa, a post he held for a year.

[3][6][7] After the proclamation of the Armistice on 8 September, the start of Operation Achse and the flight of the king and government from Rome, Calvi di Bergolo made contact with the German commander Albert Kesselring, on behalf of Marshal Enrico Caviglia, for the cessation of the fighting that had broken out in and around the capital.

On 11 September Calvi di Bergolo issued a statement according to which German troops would have to remain outside of the city; on the same day, however, Field Marshal Kesselring declared that Rome was to be considered war zone, was subject to the German code of war, and that "strike organizers, saboteurs and snipers [would be] shot" and that Italian authorities should "prevent any act of sabotage and passive resistance".
