The Mongols came from the dry steppes, and were a fierce and powerful nomadic people. They were divided into clans that were ruled by khans, or chiefs. One khan conquered his fellow clans and rose above them all to create a massive empire. He was known by the title Genghis Khan or "Universal Leader". He made the Mongols a strong fighting force, and then set out as a smart military leader to conquer much of Asia. Soon, Genghis Khan had an empire, built brutally, but it made peace throughout Asia. After Genghis died, the empire was split into 4 sections ruled by his heirs. This time became known as Pax Maongolia. Some of Khan's heirs included Kublai Khan, Batu Khan and Hulegu Khan.
