I answered your question:)
Since you provide no picture , In the past, mongols was able to conquer almost all part of Asia and some part of eastern Europe.
So here are some territories that mongols did not conquer :
- Western Europe, such as France and England
- South East Asia , such as malaysia , Indonesia, Thailand
- Africa , such as Egypt
Soldiers from colonies around the world fought in the war. Colonies became a source of manpower and raw materials. European colonies were not passive, while there was war in Europe, they were actively involved in the fight.
When you impose such policies, you declare how much of a certain currency can enter your country, or can leave your country. If you have different currencies this could harm your economy because it might prevent others from trading with you due to currency differences. If you do things like Europeans, then you can introduce a new policy that abolishes your old currency and adopts a widely used one like the Euro. This might boost your economy because others might invest.
