The period of reign of the great successor Ablai Khan is one of the longest among the Central Asian rulers, while the discontent of the Uali khanate is mentioned in the sources to scarcity. There are a number of works in which only the fact of the existence in history of such a person as Uali Khan, and the immediate period of his reign, is stated. Currently, the life and work of Uali Khan in the literature reflects only individual episodes, collectively it has an abundance of so-called «white spots» and in some cases are characterized by the presence of tendentiousness. All currently known works about the Kazakh ruler are episodic, fragmentary and to a lesser extent presented in scientific works.
