In February 1919, Emir
Habibullah Khan went on a hunting trip to Afghanistan's
Laghman Province. Among those in his retinue were Nasrullah Khan, Habibullah's first son
Inayatullah, and Habibullah's commander-in-chief
Nadir Khan. On the evening of 20 February 1919, Habibullah was assassinated in his tent by Shuja ud-Dawla, one of the pages who slept in his tent, on orders from his younger son, Amanullah, leaving Nasrullah the heir successor to the Afghan throne. Nasrullah at first refused to take the throne and declared his allegiance to Inayatullah, Habibullah's first born. Inayatullah refused and said that his father had made Nasrullah the heir rightfully and wanted him to become Emir. All the local tribes people also gave their allegiance to Nasrullah because of his strong religious beliefs. The remainder of Habibullah's party journeyed south-east to
Jalalabad, and on 21 February 1919 reached that city, whereupon Nasrullah was declared Emir, supported by Habibullah's first son
Inayatullah.
Amanullah Khan, third son of Habibullah by Habibullah's first wife, received the news in Kabul where he had remained as the king's representative. Using this opportunity, he immediately seized control of the treasury at
Kabul and staged a coup against his uncle. He took control of Kabul and the central government, declaring war against Nasrullah. Nasrullah did not want any bloodshed in order for him to be king. He 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 could do as he pleased. Fearing that Nasrullah's supporters would rise against Amanullah, the latter went against his word and imprisoned Nasrullah and his supporters. On 28 February 1919, Amanullah proclaimed himself Emir, and had him assassinated approximately one year later while in the royal jail. == See also ==
