The Aouzou Strip (/ˈaʊzuː/; Arabic قطاع أوزو Qiṭāʿ Awzū, French: Bande d'Aozou) is a strip of land in northern Chad which lies along the border with Libya, extending south to a depth of about 100 kilometers into Chad's Borkou-Ennedi-Tibesti Region for an area of 114,000 km² and is named after the small town and oasis Aouzou. The region played a significant role in the Chadian–Libyan conflict.
The Aouzou strip was defined for the first time in the discussions between France and Italy after World War I, in relation to an award to Italy for the victory in that war. At the Paris Peace Conference, 1919, the Kingdom of Italy did not receive any of the German colonies, but instead was given the Oltre Giuba from the United Kingdom, and France agreed to give some Saharan territories to Italian Libya.
After many discussions during the 1920s, in 1935 the Franco-Italian Agreement was signed between Benito Mussolini and Pierre Laval, which included a provision under which Italy would receive the Aouzou strip, which was to be added to Libya. France's other motivations in concluding this agreement with Italy were to settle the status of the Italian Tunisian community in its protectorate of the country, to remove irredentist Italian claims to Nice, and to prevent Italy from growing closer to Nazi Germany by keeping it closely aligned with France and the United Kingdom (the Stresa Front).
