Final answer:
The Mongol Empire under Kublai Khan was the largest contiguous land empire in the world, stretching from China to Syria. The empire included present-day China, Mongolia, and parts of Central Asia. However, it eventually splintered into separate khanates.
Step-by-step explanation:
The Mongol Empire under Kublai Khan was very large, encompassing a vast territory. At its height, the Mongol Empire stretched from China in the east to Syria in the west and from Russia in the north to Korea in the south, making it the largest contiguous land empire in the world.
Kublai Khan's empire, known as the Yuan Empire, covered a significant portion of Asia, including present-day China, Mongolia, and parts of Central Asia. The empire also had influence over other regions through trade and diplomacy. However, it is important to note that Kublai Khan's attempts to hold a unified Mongol Empire together were largely in vain, as the empire had already started to splinter into four separate sections known as khanates.
