The Central African Republic (CAR; Sango: Ködörösêse tî Bêafrîka; French: République centrafricaine  pronounced: [ʁepyblik sɑ̃tʁafʁikɛn], or Centrafrique [sɑ̃tʀafʁik]) is a landlocked country in Central Africa. It is bordered by Chad to the north, Sudan to the northeast, South Sudan to the east, the Democratic Republic of the Congo and the Republic of the Congo to the south and Cameroon to the west. The CAR covers a land area of about 620,000 square kilometres (240,000 sq mi) and had an estimated population of around 4.7 million as of 2014.Most of the CAR consists of Sudano-Guinean savannas, but the country also includes a Sahelo-Sudanian zone in the north and an equatorial forest zone in the south. Two thirds of the country is within the Ubangi River basin (which flows into the Congo), while the remaining third lies in the basin of the Chari, which flows into Lake Chad.What is today the Central African Republic has been inhabited for millennia; however, the country's current borders were established by France, which ruled the country as a colony starting in the late 19th century. After gaining independence from France in 1960, the Central African Republic was ruled by a series of autocratic leaders; by the 1990s, calls for democracy led to the first multi-party democratic elections in 1993. Ange-Félix Patassé became president, but was later removed by General François Bozizé in the 2003 coup. The Central African Republic Bush War began in 2004 and, despite a peace treaty in 2007 and another in 2011, fighting broke out between government, Muslim, and Christian factions in December 2012, leading to ethnic and religious cleansing and massive population displacement in 2013 and 2014.Despite its significant mineral deposits and other resources, such as uranium reserves, crude oil, gold, diamonds, lumber, and hydropower, as well as significant quantities of arable land, the Central African Republic is among the ten poorest countries in the world. As of 2013, according to the Human Development Index (HDI), the country had a low level of human development, ranking at 185th out of 187 countries.
