When Sahara Became Desert?

Sometime between 11,000 and 5,000 years ago, after the last ice age ended, the Sahara Desert transformed.

What was the Sahara before a desert?

One of the oldest civilizations to have lived in the desert was the Kiffian civilization. Kiffians lived in the desert some 10,000 years ago during a period when the desert was going through a wet phase. Considered a Stone Age civilization, Kiffian remains were found in 2000 at a place called Gobero, which is in Niger.
