Oirat Confederation
The Four Oirats (Written Oirat: ᡑᡈᠷᡋᡈᠨᡆᡕᡅᠷᠠᡑ, Dörbön Oyirad; Mongolian: Дөрвөн Ойрад, romanized: Dörvön Oirad, pronounced [ˈtɵrw̜ʊ̈ɴ ˈɞe̯ɾ(ə)t]; Chinese: 四衛拉特) or Oirat Confederation, formerly known as the Eleuths, was the confederation of the Oirat tribes which marked the rise of the Western Mongols in the history of the Mongolian Plateau. Despite the universal currency of the term "Four Oirat" among Eastern Mongols, Oirats, and numerous explanations by historians, no consensus has been reached on the identity of the original four tribes.
