A medieval merchant could be defined as anybody who sold
goods. Merchants tended to be more
wealthy and important than other guilds,
although it
wasn’t that uncommon for a merchant to be poor and another craftsmen to be
wealthy. In the earlier medieval
ages, craftsmen and merchants were quite similar, for many guilds not only made
their products, but sold them as well. During
the later medieval ages, the two jobs became more distinguished, and the line
that divided them became thicker. When
a town and its prosperity grew, the merchants of that town would become more and
more important, and it was extremely common for the head of the merchant guild
to be head of the town, and the town government to be the members of the
merchant guild.

In the
picture to the right, the merchants
are organizing trade and industry in their town. They typically set up courts of justice, built
streets and walls, and occasionally were the caretakers and people in charge of
that certain town’s finances. In
short, the merchants were extremely important in maintaining the economy of the
town they worked in.
