Chad country profile
- 2 August 2016
- From the section Africa
A largely semi-desert country, Chad is rich in gold and uranium and stands to benefit from its recently-acquired status as an oil-exporting state.
Chad's post-independence history has been marked by instability and violence, stemming mostly from tension between the mainly Arab-Muslim north and the predominantly Christian and animist south.
Chad became an oil-producing nation in 2003, with the completion of a $4bn pipeline linking its oilfields to terminals on the Atlantic coast.
However, Africa's fifth-largest nation suffers from inadequate infrastructure, and internal conflict. Poverty is rife, and health and social conditions compare unfavourably with those elsewhere in the region.

President: Idriss Deby
Idriss Deby came to power in 1990 after toppling Chadian President Hissene Habre - with the help of the French secret service.
A shrewd tactician, Mr Deby had been President Habre's chief-of-staff, leading a series of victories over rebel forces in the 1980s and earning a reputation for courage and military prowess.
After six years in office, he set up Chad's first multi-party political system and won elections that year.
But Mr Deby appeared to have little genuine domestic support. Critics say his single biggest failure was putting his clan before his country.
He is also thought to have health problems and has been known to fly to Paris for treatment to his liver.
He gained a fifth term in elections in April 2016.
Radio is the main medium, but state control of many broadcasting outlets allows few dissenting views.
The only television station, Tele-Tchad, is state-owned and its coverage favours the government.
Reporters Without Borders has on several occasions condemned the arrest of journalists in Chad, including the publisher of an privately-owned newspaper in October 2015.
