Vittorio Emanuele Orlando was an Italian statesman, who served as the Prime Minister of Italy from October 1917 to June 1919. Orlando is best known for representing Italy in the 1919 Paris Peace Conference with his foreign minister Sidney Sonnino. He was also known as "Premier of Victory" for defeating the Central Powers along with the Entente in World War I. He was also the provisional President of the Chamber of Deputies between 1943 and 1945, and a member of the Constituent Assembly that changed the Italian form of government into a republic. Aside from his prominent political role, Orlando was a professor of law and is known for his writings on legal and judicial issues, which number over a hundred works.

The Paris Peace Conference was a set of formal and informal diplomatic meetings in 1919 and 1920 after the end of World War I, in which the victorious Allies set the peace terms for the defeated Central Powers. Dominated by the leaders of Britain, France, the United States and Italy, the conference resulted in five treaties that rearranged the maps of Europe and parts of Asia, Africa and the Pacific Islands, and also imposed financial penalties. Germany, Austria-Hungary, Turkey and the other losing nations were not given a voice in the deliberations; this later gave rise to political resentments that lasted for decades. The arrangements made by this conference are considered one of the great watersheds of 20th-century geopolitical history.
