How did the development of different languages further divide Europe after the fall of the Roman Empire?

Latin was no longer the most important language in Europe after the empire fell.
French speakers and German speakers separated Europe into two different parts, with little communication between them.
Warrior kings spoke only German, so German-speaking cities became the most powerful.
Speaking different languages meant people from different areas could no longer communicate easily with each other.
