a. true
b. false

FALSE

Explanation:

    The Mongols were nomads from Central Asia. That is why they did not take root in any of their conquered terrars.

    They were fiery warriors fighting each other over pastoral lands and attacking developed civilizations of the East and South.

     Until the twelfth century they controlled only a small area near the source of the Orkhon River and other nomadic tribes, such as the Merkit and the Naiman, had great power in the eastern steppes.

    In the early thirteenth century, the Mongol clans united and began a campaign of conquest from abroad. Following the path of the Huns, their predecessors thousands of years earlier, they created one of the largest empires the world has ever seen, the Mongol Empire.

    The Mongols inhabited the plains south of Lake Baikal in present-day Mongolia.

    At its peak, the empire stretched from Korea, across Asia, and from European Russia to the shores of the Baltic Sea.
