The khanate officially existed from 1801 to 1845, when the position of khan was abolished and the area was fully absorbed into the administration of the Russian Empire.

[2] Jäñgir, who had adopted some of the habits and tastes of the Russian nobility, was literate and educated, and upon becoming the Khan of the Bukey Horde, immediately initiated reforms.

He personally appointed foremen of the heads of departments at their birth, and determined the powers of elders and sultans to maintain order, collect taxes and promote trade.

Under Jäñger, a system of so-called "esauls" was organized — people entrusting special assignments — and "bazar sultans" to control trade.

The transition to a sedentary lifestyle was encouraged: farming, mowing, forestry, import of agricultural implements, and the development of local breeds of livestock.

The best pasture lands Jäñgir distributed to the families of Kazakh nobility, which caused great discontent throughout the Bukey Horde.

[3] From 1836 to 1838, Isatay Taymanuly and famous akyn Makhambet Otemisuly led an uprising against the rule of Jäñgir Khan occurred in the region.
