Libya is a country in North Africa. Bordering the Mediterranean Sea to the north, Libya lies between Egypt to the east, Sudan to the southeast, Chad and Niger to the south, and Algeria and Tunisia to the west. The three parts of the country are Tripolitania, the Fezzan and Cyrenaica. The name "Libya" is derived from the Egyptian term "Libu", which refers to one of the tribes of Berber peoples living west of the Nile. In Greek this became "Libya", although in ancient Greece the term had a broader meaning, encompassing all of North Africa west of Egypt, and sometimes referring to the entire continent of Africa.
