Final answer:
The Mongols, led by Genghis Khan, provided empires with new emperors, sultans, or Sons of Heaven during the period from 600 BCE to 1450 CE.
Step-by-step explanation:
An instance of Central Asian nomads providing empires with new emperors, sultans, or sons of heaven during the period circa 600 BCE to 1450 CE can be seen in the case of the Mongols.
The Mongol Empire, led by Genghis Khan, conquered vast territories, including Central Asia and the Middle East.
The Mongol rulers established their own empires, such as the Ilkhanate in Persia and Central Asia, and the Yuan Dynasty in China, thereby becoming emperors and rulers of these regions.
