The Democratic Republic of the Congo (DRC) is located in central sub-Saharan Africa, bounded by (clockwise from the southwest) Angola, the South Atlantic Ocean, the Republic of Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania across Lake Tanganyika, and Zambia. The country lies between latitudes 6°N and 14°S, and longitudes 12° and 32°E. It straddles the Equator, with one-third to the North and two-thirds to the South.
Over 200 ethnic groups populate the Democratic Republic of the Congo, of which the majority are Bantu peoples. Together, Mongo, Luba and Kongo peoples (Bantu) and Mangbetu-Azande peoples constitute around 45% of the population.
After a four-year interlude between two constitutions, with new political institutions established at the various levels of government, as well as new administrative divisions for the provinces throughout the country, a new constitution came into effect in 2006 and politics in the Democratic Republic of the Congo finally settled into a stable presidential democratic republic. The 2003 transitional constitution had established a parliament with a bicameral legislature, consisting of a Senate and a National Assembly.
