14.2 Chinggis Khan and the Early Mongol Empire

The Mongol Empire, born from tribal unification under Chinggis Khan, grew into a vast power. Through military might and smart governance, it conquered lands from China to Eastern Europe, reshaping the medieval world.

The empire's expansion continued under Ogedei and Mongke Khan, but internal conflicts led to fragmentation. Despite this, the Mongols left a lasting legacy, influencing trade, culture, and politics across Eurasia for centuries to come.
