The term “92 Uzbek tribes”, which appeared in the fifteenth-century Dasht-i Qipchaq, began to be used with a variety of meanings in the following centuries depending on the political and cultural context. Near the end of the 16th century, the Uzbek states of Bukhara and Khorazm began to weaken because of their endless wars against each other and the Persians and because of strong competition for the throne among the khans in power and their heirs. At the beginning of the 17th century, the Shaybanid Dynasty was replaced by the Janid Dynasty.
