I'll be happy to critique your answers.
There were 2 main types of guilds, merchant guilds and craft guilds. All types of craftspeople had their own guilds, from cloth makers to cobblers to the stonemasons who built the great cathedrals.
Is that right?
That answers part of the question. What about how they grew?
