told Amanullah that he can have the kingdom, and he will take exile in Saudi Arabia. Amanullah Khan swore upon the Quran that no harm would come to Nasrullah if he returned to Kabul and then he can do as he pleased. Fearing that Nasrullah's supporters would rise against Amanullah, he went against his word and imprisoned Nasrullah and his supporters. On 28 February 1919, Amanullah proclaimed himself Emir, and on 3 March 1919 Nasrullah was arrested by Amanullah's forces. On 13 April 1919, Amanullah held a Durbar (a royal court under the supervision of Amanullah) in Kabul which inquired into the death of Habibullah. It found a colonel in the Afghanistan military guilty of the crime, and had him executed. On manufactured evidence, it found Nasrullah complicit in the assassination. He imprisoned Nasrullah to life imprisonment, and had him assassinated approximately one year later while in the royal jail.
