Overview
The Kingdom of Afghanistan was a constitutional monarchy in Central Asia established in 1926 as a successor state to the Emirate of Afghanistan. It was proclaimed by its first king, Amanullah Khan, seven years after he acceded to the throne. The monarchy ended in the 1973 Afghan coup d'état.
History
Emir Amanullah Khan was keen on modernizing Afghanistan, provoking several uprisings led by his conservative opponents. One such rebellion broke out while he was visiting Europe in 1927. He abdicated in favour of his brother Inayatullah Khan, who only ruled for three days before the leader of the rebellion Habibullāh Kalakāni took power and reinstated the Emirate.
After 10 months, Amanullah Khan's Minister of War, Mohammad Nadir, returned from exile in India. His armies ousted the Saqqawist government and sacked Kabul. Afterwards, Nadir's forces apprehended and subsequently executed Kalakāni. Mohammed Nadir reinstated the kingdom, was proclaimed King of Afghanistan as Mohammad Nadir Shah in October 1929, and went on to revert the reformist path of the last king, Amanullah Khan. He was succeeded by his son, Mohammad Zahir Shah, whose rule started in 1933 and lasted for 39 years. Zahir Shah, the last King of Afghanistan, was eventually overthrown by his own cousin Mohammad Daoud Khan who successfully ended the centuries-old monarchy and established a republic. It was under the leadership of Zahir Shah that the Afghan government sought relationships with the outside world, most notably with the Soviet Union, France, Great Britain, and the United States.
On 27 September 1934, during the reign of Zahir Shah, the Kingdom of Afghanistan joined the League of Nations. During World War II, Afghanistan remained neutral and pursued a diplomatic policy of non-alignment. Though being neutral in World War II, Afghanistan had relations with Nazi Germany, but that was severed after the Anglo-Soviet invasion of Iran.
