Name

In 1271, Kublai Khan imposed the name Great Yuan (Chinese: 大元; pinyin: Dà Yuán), establishing the Yuan dynasty. "Dà Yuán" (大元) is from a clause " 大哉乾元 " (dà zāi Qián Yuán; ' Great is Qián ', ' the Primal ') in the Commentaries on the I Ching section regarding the first hexagram (乾). The Mongolian-language counterpart was Dai Ön Ulus, also rendered as Ikh Yuan Üls or Yekhe Yuan Ulus. In Mongolian, Dai Ön a borrowing from Chinese, was often used in conjunction with the "Yeke Mongghul Ulus" (大蒙古國; 'Great Mongol State'), which resulted in the form ᠳᠠᠢ ᠥᠨ ᠶᠡᠬᠡ ᠮᠣᠩᠭᠣᠯ ᠤᠯᠤᠰ (大元大蒙古國; Dai Ön Yeqe Mongɣul Ulus, lit. "Great Yuan – Great Mongol State") or ᠳᠠᠢ ᠦᠨ ᠺᠡᠮᠡᠺᠦ ᠶᠡᠬᠡ ᠮᠣᠩᠭᠣᠯ ᠤᠯᠤᠰ (Dai Ön qemeqü Yeqe Mongɣol Ulus, lit. "Great Mongol State called Great Yuan").

As per contemporary historiographical norm, "Yuan dynasty" typically refers to the realm with its main capital in Dadu (modern-day Beijing). However, the Han -style dynastic name "Great Yuan" and the claim to Chinese political orthodoxy were meant for the entire Mongol Empire when the dynasty was proclaimed. This usage is seen in the writings, including non-Chinese texts, produced during the time of the Yuan dynasty. In spite of this, "Yuan dynasty" is not commonly used in the broad sense of the definition by modern scholars due to the division of the Mongol Empire. Some scholars believe that 1260 was the year that the Yuan dynasty emerged with the proclamation of a reign title following the collapse of the unified Mongol Empire.

The Yuan dynasty is sometimes also called the "Mongol dynasty" by westerners, akin to the Qing dynasty sometimes being referred to as the "Manchu dynasty" or "Manchu Dynasty of China". Furthermore, the Yuan is sometimes known as the "Empire of the Great Khan" or "Khanate of the Great Khan", since Yuan emperors held the nominal title of Great Khan; these appeared on some Yuan maps. However, both terms can also refer to the khanate within the Mongol Empire directly ruled by Great Khans before the actual establishment of the Yuan dynasty by Kublai Khan in 1271.
