How did Cote d'Ivoire get its name?

Côte d'Ivoire is French for "Ivory Coast". It is named for its trade in ivory, both raw and carved. With the restrictions on the gathering and exportation of ivory to many countries, I don't know what their economy is based on now. This restriction came about due to poaching. Large numbers of elephants were being slaughtered just for their tusks, not just by the natives of this country, but from all over Africa as well.
