The City League Suggestion

There have been many Leagues of mutual cooperation within the Holy Roman Empire. The Hanseatic League, for example, was a league of merchant guilds in a commercial and defensive confederation, or the Swabian League which was a mutual defense and peacekeeping association. Some Leagues become so powerful and united that they are even viewed as a state in themselves, like the Swiss League. The Free City of the other nation has suggested that we join something similar, a cooperation of sorts, where we collaborate in matters of trade, keeping imperial peace, and supporting tribunals.
