By far the greatest use of camel trains occurs in North Africa, to conduct trade in and around the Sahara Desert. In antiquity, the Arabian Peninsula was an important route for the trade with India and Abyssinia. Camel trains have also long been used in portions of trans-Asian trade, including the Silk Road.
The history of camel trains in the United States consists mainly of an experiment by the United States Army. On April 29, 1856, thirty-three camels and five drivers arrived at Indianola, Texas. While camels were suited to the job of transport in the American Southwest, the experiment failed. Their stubbornness and aggressiveness made them unpopular among soldiers, and they frightened horses. Many of the camels were sold to private owners, others escaped into the desert. These feral camels continued to be sighted through the early 1900s, with the last reported sighting in 1941 near Douglas, Texas.
