By the reign of Yahya Karawi he had come of age and Mas'ud's supporters were ready to install him as head of state.
The situation for Lutf Allah improved when Haidar Qassib was murdered on the orders of Hasan Damghani.
Hasan then had Lutf Allah proclaimed as formal sovereign of the Sarbadars.
Lutf Allah's reign was short and consisted mostly of him acting as a figurehead for Hasan Damghani.
[1] After a few years Lutf Allah got into a disagreement with Hasan Damghani, who deposed and executed him and then took formal control of the state.
