How did the Mongols become so successful?

The Mongols became successful due to their exceptional military organization, strategic use of cavalry, and innovative tactics, such as feigned retreats. They capitalized on the weaknesses of their enemies and employed psychological warfare to instill fear. Additionally, their ability to adapt and integrate conquered peoples into their ranks enhanced their strength. Strong leadership, particularly under Genghis Khan, also played a crucial role in unifying and directing their efforts.
