Italy was a formal member of the
Triple Alliance, alongside Germany and Austria-Hungary. However it also maintained good relations with France and Russia. The other countries understood this duality, and did not expect Italy to join in the war in 1914. Its treaty obligations did not require it to join with Germany and Austria, and it saw very little to gain from doing so. Public opinion wanted peace, and the leadership in Rome realized how poorly prepared the nation was in contrast to the powerhouses at war. By late 1914, however, Prime Minister Antonio Salandra and Foreign Minister Sidney Sonnino decided that major territorial gains were possible by joining
the Allies, and would help calm extremely serious internal dissension, by bringing glory to the victorious army, as well as satisfying popular feeling by freeing Italian-speaking territories from Austrian rule. There were also new patronage opportunities and political victories for the politicians. They planned to argue, plausibly, that these results would be the triumphant climax of "
Risorgimento" (that is, Italian unification). In December 1914 Sonnino opened negotiations in Vienna, asking for territorial compensation in return for remaining neutral. These talks were designed to conceal the government's true intentions from the Italian public opinion, and from the countries at war. In March 1915 Sonnino began serious negotiations with London and France . The
Treaty of London was signed on 26 April 1915 and Italy declared war against Austria-Hungary on 23 May 1915. Salandra boasted that the Pact of London was "the greatest, if not the first completely spontaneous act of foreign policy executed by Italy since the Risorgimento." From the standpoint of its erstwhile allies, Italy's recent success in occupying
Libya as a result of the
Italo-Turkish War had sparked tension with its
Triple Alliance allies, who had been seeking closer relations with the
Ottoman Empire. Germans reacted to Italy's aggression by singing anti-Italian songs. Italy's relations with
France remained tense: France still felt betrayed by Italy's refusal to help in the
Franco-Prussian War back in 1870.
Italy's relations with Great Britain had been impaired by constant Italian demands for more recognition in the international stage following its occupation of Libya and its demands that other nations accept its spheres of influence in Eastern Africa and the Mediterranean Sea. In the Mediterranean,
Italy's relations with Greece were aggravated when Italy occupied the Greek-populated
Dodecanese Islands, including
Rhodes, from 1912 to 1914. These islands had been formerly controlled by the Ottoman Empire. Italy and Greece were also in open rivalry over the desire to occupy
Albania. King Victor Emmanuel III himself was uneasy about Italy pursuing distant colonial adventures and said that Italy should prepare to take back Italian-populated land from
Austria-Hungary as the "completion of the Risorgimento". This idea put Italy at odds with Austria-Hungary.
Freemasonry was an influential semi-secret force in Italian politics with a strong presence among professionals and the middle class across Italy, as well as among the leadership in parliament, public administration, and the army. The two main organization were the Grand Orient and the Grand Lodge of Italy. They had 25,000 members in 500 or more lodges. Freemasons took on the challenge of mobilizing the press, public opinion, and the leading political parties in support of Italy's joining the war as an ally of France and Great Britain. In 1914–15 they temporarily dropped their traditional pacifistic rhetoric and adopted the objectives of the nationalists. Freemasonry had historically promoted cosmopolitan universal values, and by 1917 onwards they reverted to their internationalist stance and pressed for the creation of a
League of Nations to promote a new post-war universal order based upon the peaceful coexistence of independent and democratic nations. ==Internal instability==
