Libya extends over 1,759,540 square kilometres (679,362 sq mi), making it the 17th largest nation in the world by size. Libya is somewhat smaller than Indonesia in land area, and roughly the size of the US state of Alaska. It is bound to the north by the Mediterranean Sea, the west by Tunisia and Algeria, the southwest by Niger, the south by Chad and Sudan and to the east by Egypt. Libya lies between latitudes 19° and 34°N, and longitudes 9° and 26°E.
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.
