Malla Beg, upon seizing the Kokandian khan's throne in November 1858, rewarded Alimqul with several successive promotions.
In 1860, already governor of Marghilan, Alimqul was in charge of a large Kokandian force that defeated invaders from the Emirate of Bukhara.
Alimqul actively participated in the struggle for power that ensued after the death of Malla Beg in a February, 1862, coup.
He soon succeeded in thwarting Bukhara's attempt to bring Khudayar Khan back to power.
Once established as Kashgar's ruler, Buzurg and Yaqub sent Alimqul an ambassador, Mir Baba, with rich gifts.
