Did they have merchants in the medieval days where there was royalty like kings and queens?

[John P]

Kings and queens have existed for thousands of years and still do in some countries. Merchants (or traders as some might call them) have existed even longer, in fact they have existed ever since there were desirable things to trade, say at least from 10,000 years ago. It is surprising how far some goods travelled over 2000 years ago, e.g. Chinese goods have been found in sites dating from Roman times in western Europe. Certainly there was a large merchant class in Europe and Asia during the period of the European Middle Ages.
