An allusion is a reference to a famous person or thing used to bring something to mind.
For example,
When someone says they were "shot by Cupid's arrow", they mean they fell in love with someone, and Cupid is often used to reference falling in love.
Hope that wasn't too confusing, lol.
I don’t know, sorry, I wish I could.
Foreign attack was one great disadvantage to the Hanseatic Trade as they had their rivalry with Italian businesses and both were trying for supremacy and monopoly on sea route trade in the 13th Century.And because of foreign attacks,the Hanseatic League became very weak and disbanded. And then British and Dutch businesses took control of shipping in the region.
