Trans-Saharan trade, also known as the Arab trade, requires travel across the Sahara between West, Central, East, and North Africa. While existing from prehistoric times, the peak of trade extended from the 8th century until the early 17th century. The Sahara once had a very different environment. In Libya and Algeria, from at least 7000 BC, there was pastoralism, the herding of sheep, goats, large settlements, and pottery. Cattle were introduced to the Central Sahara (Ahaggar) from 4000 to 3500 BC. Remarkable rock paintings in places that are currently very dry, portray flora and fauna that are not present in the modern desert environment.
