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]
Ottoman Empire The Ottoman Empire (/ˈɒtəmən/; Devlet-i ʿAlīye-i ʿOsmānīye[dn 5]), also historically known in Western Europe as the Turkish Empire[8] or simply Turkey,[9] was a state that controlled much of southeastern Europe, western Asia and northern Africa between the 14th and early 20th centuries. It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bilecik Province) by the Oghuz Turkish tribal leader Osman.[10] After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans, the Ottoman Beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror.[11]
