Mir Akbar Khyber was an Afghan left-wing intellectual and a leader of the Parcham faction of People's Democratic Party of Afghanistan (PDPA). His assassination by an unidentified person or people led to the overthrow of Mohammed Daoud Khan's republic, and to the advent of a socialist regime in Afghanistan, the Democratic Republic of Afghanistan.

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.
