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.
In July 1960, there were six provinces in the Belgian Congo: Leopoldville Province, Equateur Province, Province Orientale, Kivu Province, Katanga Province, and Kasai Province. Kivu Province existed from 1933 to 1962 (under the name Province de Costermansville until 1947, from the name of its capital) and from 1966 to 1988.
The defining feature of the country is the second largest rainforest in the world. Rivers large and small snake throughout the country and with a poor road network remains the main means of transport to this day.
