Negüderi
The Negüderi, or Qara'unas, were Mongol military communities based around Ghazni in Afghanistan. In the fourteenth century they were among the Chagatai Khanate's military groups, wintering near Ghazni and summering in Ghur.
Their emirs Qazaghan and his son Abdullah dominated the western khanate until a Barlas and Suldus revolt in 1359. In 1362 Timur joined the Qara'unas under Qazaghan's grandson Husayn, then turned on him and seized Transoxiana in 1370. Subdued in the 1380s, the Negüderi became a major part of Timur's armies; Babur later recorded their descendants speaking Mongolian near Ghazni.
