This state of subservience to the central government was ended during the reign of Chagatai's grandson Alghu (1260–1266), who took advantage of the Toluid Civil War between Kublai Khan and Ariq Böke by revolting against the latter, seizing new territories and gaining the allegiance of the Great Khan's authorities in Transoxiana.
Denne tilstand af underlegenhed for staten blev afsluttet under regeringsperioden for Chagatais barnebarn Alghu (1260-1266), der udnyttede Toluid-borgerkrigen mellem Kublai Khan og Ariq Böke ved at gøre oprør mod sidstnævnte, beslaglægge nye territorier og opnå troskab fra storkhanens myndigheder i Transoxiana.
