### Instruction:
Which sub-Saharan colony was the first to gain independence?

### Input:
Imperial rule by Europeans would continue until after the conclusion of World War II, when almost all remaining colonial territories gradually obtained formal independence. Independence movements in Africa gained momentum following World War II, which left the major European powers weakened. In 1951, Libya, a former Italian colony, gained independence. In 1956, Tunisia and Morocco won their independence from France. Ghana followed suit the next year (March 1957), becoming the first of the sub-Saharan colonies to be granted independence. Most of the rest of the continent became independent over the next decade.

### Response:
Ghana was the first sub-Saharan colony to gain independence.
