Qarachi
Qarachi (Tatar: Qaraçı) (sometimes spelled Kharachi) was the highest level of nobles (beys) within Turkic khanates of the 12th through 16th centuries. These included the Siberia Khanate and Kazan Khanate. The name could be applied to the member of the four extended families: Shirin (Şirin), Barghen (Barğın), Arghen (Arğın), Qepchaq (Qıpçaq). These four were the leading non-royal clans of the Crimean Khanate.
The Qarachi beys acted as councillors and advised the Khan at court. They exercised particular influence during the reigns of Jochi and then later in the Crimean Khanate.
