A camel train or caravan is a series of camels carrying passengers and/or goods on a regular or semi-regular service between points. Although they rarely travelled faster than the walking speed of a man, camels' ability to withstand harsh conditions made them ideal for communication and trade in the desert areas of North Africa and the Arabian Peninsula for centuries, though they could only travel on routes with sufficient sources of food and water. Camel trains were also used sparingly elsewhere around the globe but during the 20th century they have been largely replaced by motorized vehicles or air traffic.
By far the greatest use of camel trains occurs between North and West Africa by the Tuareg, Shuwa and Hassaniyya, as well as by culturally-affiliated groups like the Toubou, Hausa and Songhay. These camel trains conduct trade in and around the Sahara Desert and Sahel. Trains travel as far south as central Nigeria and northern Cameroon in the west, and northern Kenya in the east of the continent. 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. As late as the early twentieth century, camel caravans played an important role connecting the Beijing/Shanxi region of eastern China with Mongolian centers (Urga, Uliastai, Kobdo) and Xinjiang. The routes went across Inner and/or Outer Mongolia. According to Owen Lattimore, who spent five months in 1926 crossing the northern edge of China (from Hohhot to Gucheng, via Inner Mongolia) with a camel caravan, demand for caravan trade was only increased by the arrival of foreign steamships into Chinese ports and the construction of the first railways in eastern China, as they improved access to the world market for such products of western China as wool.
