Libya (/ˈlɪbiə/ ; Arabic: ليبيا, romanized: Lībiyā), officially the State of Libya (Arabic: دولة ليبيا, romanized: Dawlat Lībiyā), is a country in the Maghreb region in North Africa. It is bordered by the Mediterranean Sea to the north, Egypt to the east, Sudan to the southeast, Chad to the south, Niger to the southwest, Algeria to the west, and Tunisia to the northwest. Libya is made of three historical regions: Tripolitania, Fezzan, and Cyrenaica. With an area of almost 700,000 square miles (1.8 million km2), it is the fourth-largest country in Africa and the Arab world, and the 16th-largest in the world. Libya has the 10th-largest proven oil reserves in the world. The largest city and capital, Tripoli, is located in western Libya and contains over three million of Libya's seven million people. Libya has been inhabited by Berbers since the late Bronze Age as descendants from Iberomaurusian and Capsian cultures. In ancient times, the Phoenicians established city-states and trading posts in western Libya, while more recently the Ottoman Empire controlled the northern coastline of Libya. Parts of Libya were variously ruled by Carthaginians, Persians, Egyptians and Macedonians before the entire region becoming a part of the Roman Empire. Libya was an early center of Christianity. After the fall of the Western Roman Empire, the area of Libya was mostly occupied by the Vandals until the 7th century when invasions brought Islam to the region. In the 16th century, the Spanish Empire and the Knights of St John occupied Tripoli until Ottoman rule began in 1551. Libya was involved in the Barbary Wars of the 18th and 19th centuries. Ottoman rule continued until the Italo-Turkish War, which resulted in the Italian occupation of Libya and the establishment of two colonies, Italian Tripolitania and Italian Cyrenaica (1911–1934), later unified in the Italian Libya colony from 1934 to 1943.
