Algeria, officially the People's Democratic Republic of Algeria, is a country located in North Africa. It is the largest country of the Mediterranean sea, second largest in the Arab World, and the second largest on the African continent and the eleventh-largest country in the world in terms of land area. There are several UNESCO World Heritage Sites. Algeria is divided into 48 provinces, 553 districts and 1,541 municipalities. Each province, district,... and municipality is named after its seat, which is mostly also the largest city. In Algeria there are 43 universities, 10 colleges, and 7 institutes for higher learning.

Algeria’s financial and economic indicators improved during the mid-1990s, now the fossil fuels energy sector is the backbone of Algeria's economy, accounting for roughly 60% of budget revenues, 30% of GDP, and over 95% of export earnings. The country ranks fourteenth in petroleum reserves, containing 11.8 billion barrels of proven oil reserves with estimates suggesting that the actual amount is even more. The U.S. Energy Information Administration reported that in 2005, Algeria had 160 trillion cubic feet of proven natural gas reserves, the eighth largest in the world.

Algiers is the capital and largest city of Algeria, and the second largest city in the Maghreb (after Casablanca). According to the 1998 census, the population of the city proper was 1,519,570 and that of the urban agglomeration was 2,135,630. A recent UN estimate of the urban agglomeration (metropolitan area) puts the population at 3,354,000 as of 2007. Nicknamed El-Bahdja or alternatively Alger la Blanche ("Algiers the White") for the glistening white of its buildings as seen rising up from the sea, Algiers is situated on the west side of a bay of the Mediterranean Sea. The city name is derived from the Arabic word al-jazā’ir, which translates as the islands, referring to the four islands which lay off the city's coast until becoming part of the mainland in 1525. Al-jazā’ir is itself a truncated form of the city's older name jazā’ir banī mazghannā, "the islands of (the tribe) Bani Mazghanna", used by early medieval geographers such as al-Idrisi and Yaqut al-Hamawi. Algiers is the only Algerian city with an English name different from its French name. The city is consistently ranked one of the least livable capitals in the world. The modern part of the city is built on the level ground by the seashore; the old part, the ancient city of the deys, climbs the steep hill behind the modern town and is crowned by the casbah or citadel, 400 feet (122 m) above the sea. The casbah and the two quays form a triangle.
