Had to look up (in Wikipee) what happened with the Central African Republic since then.
As things got more "democratic" there, the situation got more turbulent. Civil wars took over the place of the relatively peaceful years between coups, the latest is still ongoing. Foreign peacekeeping missions also involved.
Btw the CAR isn't that big of a country, the population is less than 5 million. And they are divided between 80 ethnicities. From the Wikipee article alone it is hard to say how much role this plays in the wars.
Noteworthy: at the end of the Bush War, the rebels achieved the integration of their forces into the army. This is the same what the Tuaregs in Mali demanded (and also achieved).
