[Verginius Rufus]

The maximum Mongol extension into eastern Europe was earlier in the 1200s, well before Marco Polo’s time. They destroyed the city of Kiev.

I just read up on the Mongol expansion. Apparently they made it all the way to the Danube River in Hungary.
They attempted to take over Poland after destroying Kiev, but failed. They also conquered Syria and attempted to take over Egypt, but failed.

Later on they twice tried to conquer Japan but each time their fleet was destroyed by a typhoon. Which the Japanese called the Kamikaze (Divine Wind).
