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]
Mongol invasions and conquests Tartar and Mongol raids against Russian states continued well beyond the start of the Mongol Empire's fragmentation around 1260. Elsewhere, the Mongols' territorial gains in China continued into the 14th century under the Yuan dynasty, while those in Persia persisted into the 15th century under the Timurid Empire. In India, a Mongol state survived into the 19th century in the form of the Mughal Empire.
