Why is there a link between trade and religion

The link is that trade has often been used historically to spread religious beliefs. This was especially common during early ages of Islam since Arabs were really important in the trade business since they were the middle people between far east and Europe. As they opened up trading posts across the Mediterranean they also spread their religious beliefs. This is one of the reasons why the North of Africa is for example mostly Muslim.
