"Prior to 1912, Libya was a province within the Ottoman Empire and subdivided into two regions (Tripolitania in the west and Cyrenaica in the east) reflecting a long-standing ethnic and geographic division in the country. Although not administered separately, the large region reaching south into the Sahara had a different ethnic make-up compared to the rest of the country and was more connected to sub-Saharan Africa than to the Mediterranean.
