Sila is one of four departments in Ouaddaï, a region of Chad. Its capital is Goz Beïda.

The Foreign relations of Chad are motivated primarily by the desire for outside investment in Chadian industry and support for Chadian President Idriss Déby. Chad is officially non-aligned but has close relations with France, the former colonial power. Relations with neighbouring Libya and Sudan vary periodically. Lately, the Idris Déby regime has been waging an intermittent proxy war with Sudan. Other for those two countries, Chad generally has good relations with the other neighboring countries.

Chad is one of the poorest countries in the world. Economic difficulties are aggravated positioning of the country in the depths of the African continent, the unstable domestic situation and the repeated droughts. One major hurdle in the economic development of Chad is the lack of access to the sea, which impedes the export and import products. To improve the situation of foreign capital investments and start extracting crude oil.

In the 7th millennium BC, ecological conditions in the northern half of Chadian territory favored human settlement, and the region experienced a strong population increase. Some of the most important African archaeological sites are found in Chad, mainly in the Borkou-Ennedi-Tibesti Region; some date to earlier than 2,000 BC.For more than 2000 years, the Chadian Basin has been inhabited by agricultural and sedentary peoples. The region became a crossroads of civilizations. The earliest of these were the legendary Sao, known from artifacts and oral histories.

The Sao fell to the Kanem Empire, the first and longest-lasting of the empires that developed in Chad’s Sahelian strip by the end of the 1st millennium AD. The power of Kanem and its successors was based on control of the trans-Saharan trade routes that passed through the region. These states, at least tacitly Muslim, never extended their control to the southern grasslands except to raid for slaves.

Because many of the roads in Chad aren’t tarred, they become impossibly impassable in the wet season (June to September), so it’s best to travel when it’s dry. Between March and May, the average daily temperature of 45°C (113°F) also makes travel a little uncomfortable. From December to mid-February, the days are dry and warm and the nights quite cool, making this part of the year probably the best time to head to Chad.

N’Djamena (pronounced /ənʤəˈmeɪnə/, Arabic Niǧāmīnā نجامينا), population 721,000 (2005), is the capital city of Chad. It is also the largest city in the country. A port on the Chari River, near the confluence with the Logone River, it directly faces the Cameroonian town of Kousséri, to which the city is connected by a bridge. It is also a special statute region, divided in 10 arrondissements. It is a regional market for livestock, salt, dates, and grains. Meat processing is the chief industry.

Chad (French: Tchad; Arabic: تشاد‎), officially the Republic of Chad, is a landlocked country in central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon and Nigeria to the southwest, and Niger to the west. Due to its distance from the sea and its largely desert climate, the country is sometimes referred to as the “Dead Heart of Africa”. Chad is divided into three major geographical regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanese savanna zone in the south. Lake Chad, after which the country is named, is the largest wetland in Chad and the second largest in Africa. Chad’s highest peak is the Emi Koussi in the Sahara, and the largest city by far is N’Djamena, the capital. Chad is home to over 200 different ethnic and linguistic groups. French and Arabic are the official languages. Islam is the most widely practiced religion.

Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbers. By the end of the 1st millennium BC, a series of states and empires rose and fell in Chad’s Sahelian strip, each focused on controlling the trans-Saharan trade routes that passed through the region. France conquered the territory by 1920 and incorporated it as part of French Equatorial Africa. In 1960 Chad obtained independence under the leadership of François Tombalbaye. Resentment towards his policies in the Muslim north culminated in the eruption of a long-lasting civil war in 1965. In 1979 the rebels conquered the capital and put an end to the south’s hegemony. However, the rebel commanders fought amongst themselves until Hissène Habré defeated his rivals. He was overthrown in 1990 by his general Idriss Déby. Recently, the Darfur crisis in Sudan has spilt over the border and destabilised the nation.

While many political parties are active, power lies firmly in the hands of President Déby and his political party, the Patriotic Salvation Movement. Chad remains plagued by political violence and recurrent attempted coups d’état, and is one of the poorest and most corrupt countries in the world; most Chadians live in poverty as subsistence herders and farmers. Since 2003 crude oil has become the country’s primary source of export earnings, superseding the traditional cotton industry.
