Forces loyal to Nadir captured Kabul and subsequently sacked the city, and he arrived in the city on the 15th. He captured Kalakani and executed him by firing squad on the west wall of the Arg on 1 November 1929, along with Kalakani's brother, and 9 other members of Kalakani's inner circle. King of Afghanistan As Shah of Afghanistan Nadir Khan quickly abolished most of Amanullah Khan's reforms, but despite his efforts to rebuild an army that had just been engaged in suppressing a rebellion, the forces remained weak while the religious and tribal leaders grew strong. Nadir faced many insurrections, including the Koh Daman revolt (29 November – 30 June), the Shinwari rebellion (February 1930), operations against Ibrahim Beg (November 1930 – April 1931), the Ghilzai threat (1931), the Darre Khel revolt (November 1932), and disturbances in Khost. The same year, a Soviet force crossed the border in pursuit of an Uzbek leader whose forces had been harassing the Soviets from his sanctuary in Afghanistan. He was driven back to the Soviet side by the Afghan army in April 1930, and by the end of 1931 most uprisings had been subdued. Nadir Khan named a ten-member cabinet, consisting mostly of members of his family, and in September 1930 he called into session a loya jirga of 286 which confirmed his accession to the throne. In 1931, the King promulgated a new constitution. Despite its appearance as a constitutional monarchy, the document effectively instituted a Royal oligarchy, and popular participation was merely an illusion. Although Nadir Khan placated religious factions with a constitutional emphasis on orthodox denominational principles, he also took steps to modernize Afghanistan in material ways, although far less obtrusively than Amanullah. He improved road construction, especially the Great North Road through the Hindu Kush, methods of communication, and helped establish Afghanistan's first university in 1931; however, this university (Kabul University) did not admit any students until 1932. He forged commercial links with the same foreign powers that Amanullah had established diplomatic relations with in the 1920s, and, under the leadership of several prominent entrepreneurs, he initiated a banking system and long-range economic planning. Although his efforts to improve the army did not bear fruit immediately, by the time of his death in 1933 Nadir Shah had created a 40,000-strong military force. Assassination On 8 November 1933, Nadir Khan was visiting a high school and was shot dead
