by the 13th century the blank was the largest land empire at that point
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]
Maurya Empire The Maurya Empire was a geographically extensive Iron Age historical power founded by Chandragupta Maurya which dominated ancient India between 322 BCE and 187 BCE. Extending into the kingdom of Magadha in the Indo-Gangetic Plain in the eastern side of the Indian subcontinent, the empire had its capital city at Pataliputra (modern Patna).[2][3] The empire was the largest to have ever existed in the Indian subcontinent, spanning over 5 million square kilometres (1.9 million square miles) at its zenith under Ashoka.
