Historically the area of Libya was considered three provinces (or states), Tripolitania in the northwest, Barka (Cyrenaica) in the east, and Fezzan in the southwest. It was the conquest by Italy in the Italo-Turkish War that united them in a single political unit.
Libya is a large country with a relatively small population, but the population is concentrated very narrowly along the coast. Population density is about 50 persons per km² (130/sq. mi.) in the two northern regions of Tripolitania and Cyrenaica, but falls to less than one person per km² (2.6/sq. mi.) elsewhere.
Sunni Islam of Maliki school of jurisprudence is the dominant religion in Libya. Other than the overwhelming majority of Sunni Muslims, there are also small Christian communities, composed exclusively of foreigners. Coptic Orthodox Christianity, which is the Christian Church of Egypt, is the largest and most historical Christian denomination in Libya.
