Aachen, its full name the Free Imperial City of Aachen, is a civilization in Age of History II. It doesn't show up in many scenarios, only the 1440 scenario. It does not have a leader.
Aachen shows up in the 1440 scenario with the City State ideology and Prince title inside the Holy Roman Empire. Its capital is Malmedy, despite the real capital being Aachen. It is a reoccurring theme throughout the Holy Roman Empire because of how small every state was inside of it.
- The flag of Aachen in-game does not match up with the historical city-state flag or the current modern city flag, though it is more similar to the coat of arms of the historical city state.
