Why do you think the middle class emerged? how would this change society as people knew it? how would this middle class affect the peasants and nobles? what would they think of it?

Merchants in the middle ages were business people who participated in retail and trade. The term “merchant” comes from the Latin term “mercer” which means trafficking and from the French term “mercies” which means wares. Thus, the medieval merchant was seen as both a trader and trafficker of wares across countries. The middle ages merchant sourced for his products during his travels and would then sell them in markets and shops or at fairs.
