The People's Democratic Party of Afghanistan (PDPA) was a Marxist–Leninist political party in Afghanistan established on 1 January 1965. Four members of the party won seats in the 1965 Afghan parliamentary election, reduced to two seats in 1969, albeit both before parties were fully legal. For most of its existence, the party was split between the hardline Khalq and moderate Parcham factions, each of which claimed to represent the "true" PDPA.

Mohammad Daoud Khan was an Afghan military officer and politician 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, served as the first president of Afghanistan from 1973 until his assassination in the Saur Revolution.
