Üliger (Mongolian: үлгэр, tale) is the general term given to tales and popular myths of the Mongols (included in Buryats) of north-east Asia. They are an important part of the oral traditions among the Buryats and other Siberian tribes, and among other functions, were used to orally transmit Buddhist birth stories. The tales are significant in Mongolian literature, given its long-standing tradition of passing stories on by word of mouth.
Traditionally, üligers are delivered orally in alliterative verses, often taking the form of couplets or quatrains. Like other epics in oral literature, individual üliger can vary greatly in length and content from one occasion to the next. One famous performer, the Inner Mongolian Muu-ōkin, "was said to be able to recite üliger that lasted for months." Like other epic poets, üliger performers accompanied themselves with an instrument, in this case a four-stringed fiddle.
Üligers generally tell the legends of mythological and historical heroes. Common as the villain in the üliger is a monster with several heads, known as the "manggus," whom the hero consistently defeats. The setting for the telling of these tales was usually around the fire in the winter. Under usual circumstances üliger are only told in the wintertime; reciting them in the summer may cause winter weather to return.
Popular üligers include the proverbs attributed to Genghis Khan, and the epics surrounding Khan's life, including the tale about his two white horses. Still recited today by Mongolian singers are üligers based on the story of Hua Guan Suo, one of the warriors from the Romance of the Three Kingdoms. Longer myths, such as the Epic of King Gesar, were important vehicles for the transmission of shamanic traditions. Oirad epics relayed in üligers are Jangar, the history of the four Oirad's Victory over the Mongols, Khan Kharangui, Bum Erdene, etc.
