Sardar Mohammed Daoud Khan (), also romanized as Daud Khan or Dawood Khan (18 July 1909 – 28 April 1978), was an Afghan politician and general who served as Prime Minister of Afghanistan from 1953 to 1963 and, as leader of the 1973 Afghan coup d'état which overthrew the monarchy, became the first President of Afghanistan in 1973, establishing an autocratic one-party system. Born into the Afghan royal family, Khan started as a provincial governor and later a military commander before being appointed as Prime Minister by his cousin, King Mohammed Zahir Shah. Having failed to persuade the King to implement a one-party system, Khan overthrew the monarchy with the backing of Afghan Army officers, and proclaimed himself the first President of the Republic of Afghanistan. Khan was known for his autocratic rule, and for his educational and progressive social reforms. Under his regime, he headed a purge of communists in the government, and many of his policies also displeased religious conservatives and liberals who were in favor of restituting the multiparty system that existed
