I want to know the answer to the following question:
What was the name of the route that linked Germany,Switzerland , Netherlands, and England
All the background I'm provided with is that "Cities such as Colmar and Hagenau also began to grow in economic importance and gained a kind of autonomy within the "Decapole" or "Dekapolis", a federation of ten free towns.". Is that enough to answer the question?
Answer: no
