Quick Answer
The Sahara became a desert roughly around 3,000 to 4,000 years ago after a much wetter period ended.
The Full Story
The Sahara Desert did not always look like it does today. After the African Humid Period ended, the region became much drier roughly between 3,000 and 4,000 years ago. The transition was driven by long-term changes in Earth’s climate and monsoon patterns. The Sahara now covers about 9 million square kilometers, making it the world’s largest hot desert. Ancient rock art and lake deposits show that parts of the region once supported grasslands, lakes, and wildlife.
