Is Djibouti really the ONLY African country that shares its name with its capital?
Djibouti is TINY – less than a million people – and most of them live in the capital city, Djibouti. So that might be why. Most of the rest of the country is incredibly hot and arid – can’t grow anything, etc. Some people (many in Africa) refer to Congo and Democratic Republic of Congo as Congo-Brazzaville and Congo-Kinshasa, so you could say that those are also called by their capital names.
