Mohammed Daoud Khan or Daud Khan (18 July 1909 – 28 April 1978) was the 5th Prime Minister of Afghanistan from 1953 to 1963 and the President of Afghanistan from 1973 to 1978.
Born into the royal family, he overthrew the Musahiban monarchy of his first cousin Mohammed Zahir Shah and declared himself as the first President of Afghanistan in 1973 with Soviet backing.
He would hold this position until his assassination in 1978 during the Saur Revolution led by the communist People's Democratic Party of Afghanistan (PDPA) after he fell out of favor with the USSR.
Khan was known for his progressive policies, efforts to improve women's rights, Pashtun nationalism, irredentist claims to land in northwest Pakistan, and for initiating two five-year modernization plans which increased the labor force by about 50 percent.
The 1978 coup and assassination plunged Afghanistan into an ongoing civil war.
