What is "khanbaliq"

Khanbaliq or Dadu was the capital of the Yuan dynasty, the main center of the Mongol Empire founded by Kublai Khan and in what is now Beijing, also the capital of China today. It was located at the center of modern Beijing. The Secretariat (Zhongshu Sheng) directly administered the Central Region of the Yuan Empire (comprising present-day Beijing, Hebei, Shandong, Shanxi, and parts of Henan and Inner Mongolia) and dictated policies for the other provinces. Kublai and his successors also claimed supremacy over the entire Mongol Empire, although in practice that had already fragmented into a number of khanates since the death of Möngke Khan.
