What do you mean?i dont get the question sorry
I could be wrong but I think it is revise.
<span>The guilds in the Middle Ages were an important part of life in Medieval times. A higher social status could be achieved through guild membership, and feudalism encouraged people to do this. There were many advantages of becoming a member of a guild. Guild members in the Middle Ages were supported by the Guild if they became sick. There were two main kinds of Medieval guilds - Merchant Guilds and Craft Guilds. A man would have to work through three phases to become an elite member of a Medieval Guild during the Middle Ages - apprentice, journeyman and master.</span>
1) Their position on land gave them protection from invasion
2) Surplus on land, meaning they had good soil ideal for agriculture.
3) Rome was at the center of trade due to it's position at the center of the Mediterranean Sea.
Lol to sum it up, Protection from invasion, fertile land and Center for trade.
Eh, tell me if I'm right? I at least known for a fact the first one is.
