Italian protectorate of Albania (1939–1943) in the context of Treaty of Paris (1947)

The Italian invasion of Albania was a brief military campaign which was launched by Italy against Albania in 1939. The conflict was a result of the imperialistic policies of the Italian prime minister and dictator Benito Mussolini. Albania was rapidly occupied, its ruler King Zog I went into exile in the neighboring Kingdom of Greece, and the country was made a part of the Italian Empire as a protectorate in personal union with the Italian Crown.

The Paris Peace Treaties (French: Traités de Paris) were signed on 10 February 1947 following the end of World War II in 1945. The Paris Peace Conference lasted from 29 July until 15 October 1946. The victorious wartime Allied powers (principally the United Kingdom, Soviet Union, United States, and France) negotiated the details of peace treaties with those former Axis allies, namely Italy, Romania, Hungary, Bulgaria, and Finland, of which all but Hungary had switched sides and declared war on Germany during the war. They were allowed to fully resume their responsibilities as sovereign states in international affairs and to qualify for membership in the United Nations.

The settlement elaborated in the peace treaties included payment of war reparations, commitment to minority rights, and territorial adjustments including the end of the Italian colonial empire in North Africa, East Africa, Yugoslavia, Greece, and Albania, as well as changes to the Italian–Yugoslav, Hungarian–Czechoslovak, Soviet–Romanian, Hungarian–Romanian, French–Italian, and Soviet–Finnish borders. The treaties also obliged the various states to hand over accused war criminals to the Allied powers for war crimes trials.

The Greco-Italian War, also called the Italo-Greek War, took place between Italy and Greece from 28 October 1940 to 23 April 1941. This conflict began the Balkans campaign of World War II between the Axis powers and the Allies, and eventually turned into the Battle of Greece with British and German involvement. On 10 June 1940, Italy declared war on France and the United Kingdom. By September 1940, the Italians had invaded France, British Somaliland and Egypt. This was followed by a hostile press campaign in Italy against Greece, accused of being a British ally. A number of provocations culminated in the sinking of the Greek light cruiser Elli by the Italians on 15 August. On 28 October, Mussolini issued an ultimatum to Greece demanding the cession of Greek territory, which the Prime Minister of Greece, Ioannis Metaxas, rejected.

Italy's invasion of Greece, launched with the divisions of the Royal Army based in Italian-controlled Albania, badly armed and poorly commanded, resulted in a setback: the Italian forces encountered unexpectedly tenacious resistance by the Hellenic Army and penetrated only a few kilometers into Greek territory and had to contend with the mountainous and muddy terrain on the Albanian–Greek border. With British air and material support, the Greeks stopped the Italian invasion just inside Greek territory by mid-November and subsequently counter-attacked with the bulk of their mobilized army to push the Italians back into Albania – an advance which culminated in the Capture of Klisura Pass in January 1941, a few dozen kilometers inside the Albanian border. The defeat of the Italian invasion and the Greek counter-offensive of 1940 have been called the "first Axis setback of the entire war" by Mark Mazower.
