The Italo-Turkish War between the Kingdom of Italy and the Ottoman Empire over Italian claims in Libya is ongoing. While Italian conscripts faced death in the Libyan desert, a new electoral law grants almost universal male suffrage; the electorate, below 3 million in 1909, rises to nearly 8.5 million.
January 7 – The Battle of Kunfuda Bay, the largest naval battle of the Italo-Turkish War in the Red Sea. the Italian cruiser Piemonte, with the Soldati Artigliere class destroyers Artigliere and Garibaldino, sank seven Turkish gunboats. Successively the Italians blocked and damaged the main ports of Yemen.
February 24 – Battle of Beirut: Italy launches a surprise attack on the Ottoman port of Beirut; the cruiser Giuseppe Garibaldi and the gunboat Volturno bombard the harbour, killing 97 sailors and civilians. As a result of the battle all Ottoman naval forces in the region were annihilated, thus ensuring the approaches to the Suez Canal were open to the Italians. The Ottoman naval presence at Beirut was completely annihilated and casualties on the Ottoman side were heavy. The Italian navy gained complete naval dominance of the southern Mediterranean for the rest of the war.
March 6 – Italian forces are the first to use airships in war, as two dirigibles drop bombs on Turkish troops encamped at Janzur in north-western Libya, from an altitude of 6,000 feet. Although Italy could extend its control to almost all of the 2,000 km of the Libyan coast between April and early August 1912, its ground forces could not venture beyond the protection of the navy's guns and were thus limited to a thin coastal strip.
May – Italy occupies 13 Turkish-held Dodecanese islands, including Rhodes, in the Aegean Sea.
July 10 – The Italian Reformist Socialist Party is founded by leading reformists Leonida Bissolati and Ivanoe Bonomi who had been expelled from the Italian Socialist Party because of their desire of entering in the majority supporting Prime Minister Giovanni Giolitti. Bissolati's refusal to oppose the war with Turkey for the conquest of Libya triggered his resignation as socialist Member of Parliament in February 1912.
October 18 – With the Treaty of Lausanne in Ouchy near Lausanne the Italo-Turkish War ends. The war costs Italy 1.3 billion lire, nearly a billion more than Prime Minister Giovanni Giolitti estimated before the war, ruining ten years of fiscal prudence. Italy obtains control over the colonies of Cyrenaica and Tripolitania, as well as the Dodecanese islands. After the withdrawal of the Ottoman army the Italians could easily extend their occupation of Libya, seizing East Tripolitania, Ghadames, the Djebel and Fezzan with Murzuk during 1913.
