The Merkit (/ˈmɜːrkɪt/; Mongolian: [ˈmircɪt]; lit. 'Wise Ones') was one of the five major tribal confederations of Mongol or Turkic origin in the 12th-century Mongolian Plateau.
The Merkits lived in the basins of the Selenga and lower Orkhon River (modern south Buryatia, Bulgan Province and Selenge Province). After a struggle of over 20 years, they were defeated in 1200 by Genghis Khan and their lands were incorporated into the Mongol Empire.
