Before fragmenting, it is the largest contiguous empire in world history. I use the word contiguous because the British Empire actually covers more land, as we'll see, a few hundred years later. But the Mongolian Empire, all of the land was connected. It was contiguous. But as you can see from this drawing, they began to fragment into what's referred to as multiple khanates that become more and more independent in the second half of the 13th century. As we get into the 14th century, we can see that it is now fragmented into multiple, still very significant empires. In the east, you have Kublai Khan's Wan Dynasty controlling modern day Mongolia and China, reemphasizing the importance of Buddhism until they eventually get reconquered by the Ming Dynasty.
