Answer: At this part, "A smart count in the Champagne region of France guaranteed the safety of any merchant coming to sell or trade at the markets in the lord's lands." it kinda infers that Europe had dangerous travels. So when France showed they are guaranteeing safety it really showed in a way that Europe can be kind of dangerous. I mean why would they offer protection in the first place if nothing would happen. Or why would they offer safety upon their clients.
