Political map of Northern Africa 10 October 1911 (Italo-Turkish War): In 1902 Italy had signed a secret treaty with France, giving it the right to intervene in Ottoman Tripolitania (Libya) (Ottoman Tripolitania) in return for supporting the French in Morocco. With the eruption of the Agadir Crisis over Morocco in 1911, Italy seized its opportunity, declaring war on the Ottoman Empire (Italo-Turkish War) and quickly occupying the coast of Tripolitania (Italian invasion of Libya).
