  The Mongol Empire is also referred to as the "Mongolian Empire" or the "Mongol World Empire" in some English sources. The empire referred to itself as ᠶᠡᠬᠡ ᠮᠣᠩᠭᠣᠯ ᠤᠯᠤᠰ yeke Mongγol ulus (lit. 'nation of the great Mongols' or the 'great Mongol nation') in Mongol or kür uluγ ulus (lit. the 'whole great nation') in Turkic.
  
  After the 1260 to 1264 succession war between Kublai Khan and his brother Ariq Böke, Kublai's power became limited to the eastern part of the empire, centered on China. Kublai officially issued an imperial edict on 18 December 1271 to give the empire the Han -style dynastic name of "Great Yuan" (Dai Yuan, or Dai Ön Ulus'; Chinese: 大 元; pinyin: Dà Yuán) and to establish the Yuan dynasty. Some sources give the full Mongol name as Dai Ön Yehe Monggul Ulus.
