Khanate, or Chanat, is a Turco-Mongol-originated word used to describe a political entity ruled by a Khan. In modern Turkish, the word used is kağanlık or hanlık and in modern Azeri of the republic of Azerbaijan, xanlıq. In Mongolian the word khanlig is used, as in "Khereidiin Khanlig" meaning the Khanate of the Kerait. This political entity is typical for people from the Eurasian Steppe and it can be equivalent to tribal chiefdom, principality, kingdom or even empire.
