Origins and founding

Proclaimed on 9 June 1926 when Emir Amanullah Khan — who had won full independence from Britain in 1919 — elevated the Emirate of Afghanistan into a kingdom, becoming its first Padshah (king).

Capitals and territory

Kabul was the capital (Jalalabad briefly during the 1929 civil war). The territory, 652,864 km² including the Wakhan Corridor, was inherited from the emirate — its shape a legacy of its buffer-state role between the Russian and British empires.

Major rulers and key events

Amanullah Khan (1926–1929) pursued rapid modernisation, provoking conservative uprisings; he abdicated in favour of his brother Inayatullah, who lasted three days before the rebel Habibullah Kalakani seized power and briefly restored an emirate. After ten months, Amanullah's war minister Mohammad Nadir returned from exile, took Kabul, executed Kalakani and was proclaimed king (October 1929). Nadir Shah reversed the reformist course and was assassinated in 1933, succeeded by his son Mohammad Zahir Shah, who ruled 39 years (1933–1973). Afghanistan joined the League of Nations (1934), stayed neutral in World War II, joined the United Nations (1946) and cast the only vote against Pakistan's UN admission (1947) over the Pashtunistan issue. Prime Minister Daoud Khan (1953–63) pushed industrialisation and Soviet/Czechoslovak arms deals (1956: T-34 tanks, MiG-17s); his Pashtunistan stance led Pakistan to close the border (1961–62), and he resigned in 1963. The 1964 constitution opened a "Decade of Democracy."

Government, economy and culture

Government passed from absolute monarchy through the Loya Jirga to a bicameral National Assembly under the 1964 constitution. The economy rested on agriculture and mining (lapis lazuli, copper, iron ore); both superpowers courted neutral Afghanistan — the US Four Point Program (1951) and Helmand valley project, the Soviet Termez–Mazar pipeline (1954). Dari and Pashto (from 1936) were official; the population of ~12.1 million (1973) was ~93% Muslim with Hindu, Sikh and Jewish minorities.

Decline and end

On 17 July 1973, while Zahir Shah was abroad for medical treatment, his cousin and former prime minister Mohammad Daoud Khan staged a bloodless coup; Zahir abdicated in August to avoid civil war, ending the monarchy and inaugurating the Republic of Afghanistan.

Legacy and significance

The kingdom era is remembered as Afghanistan's longest stretch of peace and gradual modernisation in the 20th century; its Cold War balancing act and Pashtunistan dispute set patterns that dominated Afghan politics for decades after 1973.
