Shortly after a rebellion by Pashtun tribesmen and forces of Habibullah Kalakani began against the monarchy, Mohammad Nadir was exiled due to disagreements with King Amanullah. After the overthrow of Amanullah Khan's monarchy by Habibullah Kalakani, Mohammed Nadir returned to India and acquired military support from the British. He returned to Afghanistan with his British supported armies and took most of Afghanistan from Habibullah Kalakani. By October 13 of 1929, Mohammad Nadir Khan captured Kabul and subsequently sacked the city. Nadir Shah then asked for a truce with Habibullah Kalakani and asked him to join him so that they could discuss the political upheavals and come to a resolution. Nadir signed an oath on the Qur'an that he would honor his truce. Kalakani accepted Mohammed Nadir's truce and went to Nadir's meeting accompanied by Nadir's religious envoy. Despite Nadir's oath on the Qur'an and the religious envoy, upon his arrival Habibullah Kalakani was shot and hanged. Mohammad Nadir Khan then declared himself King, or Shah, of Afghanistan on October 16, 1929.
