Saur Revolution
The Saur Revolution, also known as the April Revolution or the April Coup, was a violent coup d'état and uprising staged on 27 and 28 April 1978 by the People's Democratic Party of Afghanistan (PDPA), which overthrew Afghan president Mohammad Daoud Khan, who had himself taken power in the 1973 Afghan coup d'état and established an autocratic one-party system in the country. Daoud and most of his family were executed at the Arg presidential palace in the capital city of Kabul by Khalqist (a PDPA faction) military officers, after which his supporters were also purged and killed.
