Because the Sahara desert goes all the way to the Atlantic coast. The Romans were not great seafarers and required the support of coastal towns to cover long distances. The Western Sahara represents a break in that chain, over 1000 km of inhospitable coastline. Even today, Western Sahara is one of the most sparsely populated areas in the world with an ...

This is an interesting and difficult question. Unfortunately, not much is known of Viking equipment, including clothing, because such military goods were relatively expensive and rare. For example, in those times (800-1000 AD) it was common for people to go barefoot, shoes were so expensive. Written works from the time rarely discuss viking clothing in any ...

For example, North West Africa was originally part of Carthage. After the Punic wars, the Romans simply gifted most of it to their allies/clients, the native Berber kings of Numidia and Mauretania.

The clothing was predominantly wool underclothes for warmth, supplemented with canvas over coats for protection from the wind. This worked surprisingly poorly, in the Antarctic ...
