Qara'unas

The Qara'unas or Negüderi were a Mongol people that settled in Afghanistan.

The word Qarauna derived from Mongolian word Kara meaning black Turkish. Kara meaning Black in Turkic Language. At first they were subjects to Great Khan and served as tamnas or tamachis in Afghanistan. Great Khan appointed their leaders from non-Chingisid generals such as Dayir and Mungudei. In 1238, they settled near India to face military forces of Delhi Sultanate. In 1250's their leader was Sali Noyan who was a general of tatar origin. Möngke Khan ordered Sali Noyan and his tamna soldiers to join Hulegu's army in 1253. In 1260, Jochid Baval, the father of Nogai Khan, was executed by the order of Hulegu Khan after taking permission from Berke who was the khan of the Golden Horde. Soon after that, Kuli and Tutar, also Golden Horde princes, died suspiciously. Golden Horde soldiers, who served for Hulgeu, feared for their lives and began to move to Kipchak Steppes via Derbent and other remnants went through Syria to Egypt. Angered, Hulegu punished many soldiers of Golden Horde for the defeat of Ain Jalut. Mongol general Baiju was executed as well. To the east, the flight of Jochid troops into Afghanistan in significant numbers led to the creation of the Negudari (Nikudari) Mongols or Qaraunas in 1262. Berke ordered general Neguder to raid eastern part of Ilkhanate. Sometimes, historians call Qara'unas as the Neguderis. This term was derived from the name of Negudar.
