It is true that before January of 2006, Rwanda was divided into twelve provinces. These boundaries were redrawn as part of a program to reorganize the country for the following reason. The government of Rwanda abolished the 12 provinces because it had a plan to reorganize the regions and decentralize them.
Today, Rwanda has a complex division of the country in four general provinces, not counting the city of Kigali, the capital of Rwanda. Then, there are 30 districts, 416 sectors that are divided by 2,148 cells that include 14,830 villages.
Rwanda is governed by a central government located in the capital city of Kigali and has local governments. The official language is French. They were colonized by France during the Scramble for Africa.
