The Mongol invasions of the 13th century affected much of Eurasia, where at one point, the Mongols had conquered lands stretching from China to Eastern Europe. While these invasions have been depicted as very destructive and disruptive to trade and urban life in many regions, several new developments fundamentally changed the course of history for Europe and Asia. Many of these impacts are not obvious, but the Mongols' influences, in effect, can still be felt today.
