who was the inca king who began the conquest that led to the creation of their empire
History of the Incas In 1438 AD, under the command of Sapa Inca (paramount leader) Pachacuti, whose name meant "world-shaker", they began a far-reaching expansion. The land Pachacuti conquered was about the size of the Thirteen Colonies of the United States in 1776, and consisted of about half the Andes mountain range.
Aztec Aztec culture (/ˈæztɛk/, also known as Mexica culture, was a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521, during the time in which a triple alliance of the Mexica, Texcoca and Tepaneca tribes established the Aztec empire. The Aztec people were certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries.

Empire In the thirteenth century, Genghis Khan expanded the Mongol Empire to be the largest contiguous empire in the world. However, within two generations, the empire was separated into four discrete khanates under Genghis Khan's grandsons. One of them, Kublai Khan, conquered China and established the Yuan Dynasty with the imperial capital at Beijing. One family ruled the whole Eurasian land mass from the Pacific to the Adriatic and Baltic Seas. The emergence of the Pax Mongolica had significantly eased trade and commerce across Asia.[25][26]
