Garamantes lived in fertile areas of Sahara, corresponding to the southwestern Libya, which had not always been a desert. In a period lasting from about 10,000 to 6,000 before current era, the country was like a savanna, with some perennial lakes. During the sixth millennium, several great droughts forced people to abandon the region. The lakes disappeared, leaving large fields of salt, one of the main articles of future Garamantian trade.
