Question: In what war did the Royal Navy include the Condottieri-class light cruiser Eugenio di Savoia?

full_context: Document 1: List of battleships of Italy: Starting in the 1890s, the Italian "Regia Marina" (Royal Navy) began building a series of modern battleships. Early designs were marked by their small size, light armor, and high speed compared to contemporary foreign counterparts. The first pre-dreadnought battleship design, the "Ammiraglio di Saint Bon" class , was constrained by budgetary limits imposed by the legislature. Two ships were ordered by the class's namesake, Admiral Simone de Pacoret Saint Bon, though the design was also influenced by Benedetto Brin, who replaced di Saint Bon as naval minister after his death. Brin designed the next pair of battleships, the "Regina Margherita" class . These ships were larger than the preceding class, and were intended to challenge the Austro-Hungarian "Habsburg"-class battleship s then under construction. Brin himself died during the construction process. Vittorio Cuniberti designed the next class of small pre-dreadnoughts, the "Regina Elena" class , which were the fastest battleships in the world at the time of their completion. These ships all served in the Italo-Turkish War of 1911–12, where they were primarily used to provide naval gunfire support for the Italian ground troops, as the Ottoman Navy largely confined itself to port.
Document 2: Marshal of Italy: Marshal of Italy (Italian: "Maresciallo d'Italia") was a rank in the Italian Royal Army ("Regio Esercito"). Originally created in 1924 by Italian dictator Benito Mussolini for the purpose of honoring Generals Luigi Cadorna and Armando Diaz, the rank was granted to several other general officers from 1926 to 1943. The rank was the highest in the Italian Army prior to the creation of the rank of First Marshal of the Empire in 1938. The rank of Marshal of Italy was abolished in 1946 with the creation of the Republic of Italy. The equivalent Royal Navy ("Regia Marina") rank was Grand Admiral ("Grande Ammiraglio"), while the equivalent Air Force ("Regia Aeronautica") rank was Marshal of the Air Force ("Maresciallo dell'Aria"), all of them abolished for the Armed Forces of the Republic of Italy.
Document 3: Kingdom of Italy: The Kingdom of Italy (Italian: "Regno d'Italia" ) was a state which existed from 1861, when King Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 1946, when a constitutional referendum led civil discontent to abandon the monarchy and form the Italian Republic. The state was founded as a result of the unification of Italy under the influence of the Kingdom of Sardinia, which can be considered its legal predecessor state.
Document 4: Parliament of the Kingdom of Italy: The Parliament of the Kingdom of Italy was the bicameral parliament of the Kingdom of Italy. It was established in 1861 to replace the Parliament of the Kingdom of Sardinia and lasted until 18 June 1946, when it was replaced by the present-day Italian Parliament. It was formed of a lower house (the Chamber of Deputies or after 1939 the Chamber of Fasci and Corporations) and an upper house (Senate of the Kingdom of Italy).
Document 5: Italian cruiser San Marco: The Italian cruiser "San Marco" was a "San Giorgio"-class armoured cruiser built for the Royal Italian Navy ("Regia Marina") in the first decade of the 20th century. She was the first large Italian ship fitted with steam turbines and the first turbine-powered ship in any navy to have four propeller shafts. The ship participated in the Italo-Turkish War of 1911–12, during which time she supported the occupations of Benghazi and Derna, the island of Rhodes, and bombarded the fortifications defending the entrance to the Dardanelles. During World War I, "San Marco"' s activities were limited by the threat of Austro-Hungarian submarines, although the ship did participate in the bombardment of Durazzo, Albania in late 1918. She played a minor role in the Corfu incident in 1923 and was converted into a target ship in the first half of the 1930s. "San Marco" was captured by the Germans when they occupied northern Italy in 1943 and was found sunk at the end of the war. The ship was broken up and scrapped in 1949.
Document 6: Italian cruiser Muzio Attendolo: Muzio Attendolo was a Condottieri-class light cruiser of the Italian Regia Marina, which fought in World War II. She was sunk in Naples by bombers of the United States Army Air Forces (USAAF) on 4 December 1942. Although salvaged after the war she was damaged beyond repair and was scrapped.
Document 7: Italian cruiser Luigi Cadorna: Luigi Cadorna was an Italian Condottieri-class light cruiser, which served in the "Regia Marina" during World War II; named after Italian Field Marshal Luigi Cadorna who was commander in Chief of the Italian Army during World War I.
Document 8: Italian Air Force: The Italian Air Force (Italian: Aeronautica Militare; AM) is the aerial defence force of the Italian Republic. The Air Force was founded as an independent service arm on 28 March 1923, by King Victor Emmanuel III as the "Regia Aeronautica" (which equates to "Royal Air Force"). After World War II, when Italy was made a republic by referendum, the "Regia Aeronautica" was given its current name. Since its formation the service has held a prominent role in modern Italian military history. The aerobatic display team is the Frecce Tricolori.
Document 9: Italian cruiser Eugenio di Savoia: Eugenio di Savoia was a Condottieri-class light cruiser, which served in the "Regia Marina" during World War II. She survived the war but was given as a war reparation to the Hellenic Navy in 1947. She was renamed Elli and served until 1964.
Document 10: Italian cruiser Duca degli Abruzzi: Luigi di Savoia Duca Degli Abruzzi was an Italian "Duca degli Abruzzi"-class light cruiser, which served in the Regia Marina during World War II. After the war, she was retained by the Marina Militare and decommissioned in 1961. She was built by OTO at La Spezia and named after Luigi Amedeo, Duke of the Abruzzi, an Italian explorer and Admiral of World War I.
Document 11: 1st Cavalry Division Eugenio di Savoia: The 1st Cavalry Division "Eugenio di Savoia" was an cavalry division of the Royal Italian Army during World War II. The "Eugenio di Savoia" was mobilized in 1940, as a cavalry division and took part in the Invasion of Yugoslavia. The division remained in Yugoslavia in the XI Corps (Ljubljana) as an occupying force on the coast of Dalmatia.
Document 12: Regia Marina: The Royal Navy (Italian: Regia Marina, ] ) was the navy of the Kingdom of Italy ("Regno d'Italia") from 1861 to 1946. In 1946, with the birth of the Italian Republic ("Repubblica Italiana"), the Royal Navy changed its name to Military Navy ("Marina Militare").
Document 13: Italian cruiser Coatit: Coatit was a torpedo cruiser of the Italian "Regia Marina" built in the late 1890s. She was the second and final member of the "Agordat" class . The ship, which was armed with twelve 76 mm guns and two 450 mm torpedo tubes, was too slow and short-ranged to be able to scout effectively for the fleet, so her career was limited. She saw action during the Italo-Turkish War in 1911–12, where she provided gunfire support to Italian troops in North Africa. She also caused a minor diplomatic incident from an attack on retreating Ottoman soldiers in Anatolia. "Coatit" was part of an international fleet sent to Constantinople when the city appeared to be at risk of falling to the Bulgarian Army during the First Balkan War. In 1919, she was converted into a minelayer and was sold for scrap in 1920.
Document 14: Italian institutional referendum, 1946: An institutional referendum ("referendum istituzionale", or "referendum sulla forma istituzionale dello Stato", in Italian) was held in Italy on 2 June 1946, a key event of Italian contemporary history. Until 1946, Italy was a kingdom ruled by the House of Savoy, kings of Italy since the Risorgimento and previously rulers of Savoy. However, Benito Mussolini, enjoying the support of the reigning monarch, imposed fascism after the 28 October 1922 March on Rome, eventually engaging Italy in World War II alongside Nazi Germany. In 1946, Italy became a republic after the results of a popular referendum. Monarchists had suspicions of fraud, but were never able to prove these. A Constituent Assembly was elected at the same time.
Document 15: List of marquesses in Italy: Italy, as a single nation state, began only in 1861, after the Piedmont-based Kingdom of Sardinia conquered most of present-day Italy. At that point, titles were recognized to all who held them according to the law of so-called "pre-unitarian" States. Consequently, the Kingdom of Italy had several different nobility traditions, one for each pre-unitarian State and one for the unified state (that was actually the Piedmontese-Savoyard one). That is why the Italian College of Arms, called "Consulta araldica" (heraldic council), was organized in 14 "regional" commissions. Common rules concerning all titles were established only in 1926. That is why a list of Italian marquisates has to be divided into different pre-unitarian lists, plus a unified list for titles granted after 1861. The latter should be completed with titles granted by the last King of Italy, Humbert II, during his exile and after the proclamation of the republic (1946), until his death in 1983: these concessions base upon the fact that he was not defeated in war and thus remained a king, that is a "fons honorum", but this issue is controversial, titles granted by a non-reigning king not being recognized by most noble and royal families in Europe. Only the Sovereign Military Order of Malta and the Corpo della Nobiltà Italiana recognize these titles, while the CILANE treats them as mere titles of courtesy.
