Parcham in the context of "Democratic Republic of Afghanistan"

The 1973 Afghan coup d'état, also called by Afghans as the Coup of 26 Saratan (Dari: کودتای ۲۶ سرطان) and self-proclaimed as the Revolution of 26 Saratan 1352, was led by Army General and prince Mohammad Daoud Khan against his cousin, King Mohammad Zahir Shah, on 17 July 1973, which resulted in the establishment of the Republic of Afghanistan under a one-party system led by Daoud Khan.

For the coup, Daoud Khan led forces in Kabul along with then-chief of staff General Abdul Karim Mustaghni, to overthrow the monarchy while the King was convalescing abroad in Ischia, Italy. Daoud Khan was assisted by army officers and civil servants from the Parcham faction of the PDPA, including Air Force colonel Abdul Qadir. Daoud also had the support of air force personnel stationed in Kabul International Airport and Bagram Air Base, led by Lieutenant Abdul Hamed Muhtaat and Lieutenant Pachagul Wadafar, although the flying of military aircraft over the city was not called upon. Seven loyalist police officers and one tank commander, as well as three members of his tank crew, were killed in what was described at the time by staff from the United States National Security Council as a "well planned and swiftly executed coup".

The People's Democratic Party of Afghanistan (PDPA; Dari: حزب دموکراتیک خلق افغانستان), known as the Homeland Party (Dari: حزب وطن, Hezb-e Watan) after June 1990, 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 the party was 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.

The party adhered to Marxist–Leninist ideology and toed a staunch pro-Soviet political line. The PDPA's secret constitution, which was adopted by the party during its founding congress in January 1965 but never publicly released to party cadres, described itself as "the vanguard of the working class and all laborers in Afghanistan" and defined its party ideology as "the practical experience of Marxism–Leninism". While PDPA's internal documents incorporated explicitly Marxist terminology, the party refrained from formally branding itself as "communist" in public, instead using labels such as "national democratic" and "socialist". PDPA's public platform document published in April 1966 asserted that its political objectives involved the creation of a "democratic national government" as well as the long-term goal of establishing a socialist state.

Operation Storm-333 (Russian: Шторм-333, Shtorm-333) was a military raid executed by the Soviet Union in Afghanistan on 27 December 1979. Special forces and airborne troops stormed the heavily fortified Tajbeg Palace in Kabul and assassinated Afghan leader Hafizullah Amin, a Khalqist of the People's Democratic Party of Afghanistan (PDPA) who had taken power in the Saur Revolution of April 1978. It was the start of the Soviet–Afghan War.

The assassination of Amin was part of a larger Soviet plan to secure and take control of Afghanistan with support from the PDPA's Parcham faction, which opposed the hardline ideology espoused by the rival Khalq faction; a number of Soviet troops crossed the Amu Darya and entered Afghanistan by land while others flew to airbases around the country with exiled Parchamis in preparation for the assassination. The Tajbeg Palace, located on a high and steep hill in Kabul, was surrounded by landmines and guarded by extraordinarily large contingents of the Afghan Army. Nonetheless, Afghan forces suffered major losses during the Soviet operation; 30 Afghan palace guards and over 300 army guards were killed while another 150 were captured. Two of Amin's sons, an 11-year-old and a 9-year-old, died from shrapnel wounds sustained during the clashes. In the aftermath of the operation, a total of 1,700 Afghan soldiers who surrendered to Soviet forces were taken prisoner, and the Soviets installed Babrak Karmal, the leader of the PDPA's Parcham faction, as Amin's successor.

Babrak Karmal (born Sultan Hussein; 6 January 1929 – 1 or 3 December 1996) was an Afghan communist revolutionary and politician who was the leader of Afghanistan, serving in the post of general secretary of the People's Democratic Party of Afghanistan from 1979 to 1986.

Kārmal attended Kabul University and developed openly leftist views there, having been introduced to Marxism by Mir Akbar Khyber during his imprisonment for activities deemed too radical by the government. He became a founding member of the People's Democratic Party of Afghanistan (PDPA) and eventually became the leader of the Parcham faction when the PDPA split in 1967, with their ideological nemesis being the Khalq faction. Kārmal was elected to the Lower House after the 1965 parliamentary election, serving in parliament until losing his seat in the 1969 parliamentary election.

The Khalq (Dari/Pashto: خلق, lit. 'masses' or 'people') was a faction of the People's Democratic Party of Afghanistan (PDPA). Its historical de facto leaders were Nur Muhammad Taraki (1967–1979), Hafizullah Amin (1979) It was also the name of the leftist newspaper produced by the same movement. The Khalq wing was formed in 1967 after the split of the party due to bitter resentment with the rival Parcham faction which had a differing revolutionary strategy.

It was made up primarily of Pashtuns from rural backgrounds. Its leaders preferred a mass organization approach and advocated class struggle to overthrow the system to bring about political, economic and social changes. They would rule the Democratic Republic of Afghanistan that was formed as a result of the Saur Revolution in 1978. The Khalqists introduced radical reforms and carried out brutal crackdowns on dissent turning Afghanistan into a police state run by the AGSA (and later KAM). The Khalqist crackdowns encouraged the rebellion of the religious and ethnic minority segments present in the Afghan society, which led more people joining exiled Islamist parties in Pakistan, however these rebellions did not pose an existential threat to their rule due to Khalq's large support base within the Armed Forces. Khalqist rule would be ended following Soviet military intervention in December 1979 overthrowing Hafizullah Amin.

Mohammad Najibullah Ahmadzai (Pashto; Dari: محمد نجيب الله احمدزی, 6 August 1947 – 27 September 1996) was an Afghan military officer and politician who served as the fifth president of Afghanistan from 1987 until his resignation in April 1992, shortly after the Afghan mujahideen's takeover of Kabul. He was also the General Secretary of the People's Democratic Party of Afghanistan (PDPA) from 1986 to 1992. After a failed attempt to flee to India, Najibullah remained in Kabul, and lived in the United Nations headquarters until his assassination during the Taliban's first capture of Kabul in 1996.

A graduate of Kabul University, Najibullah held different careers under the People's Democratic Party of Afghanistan (PDPA). Following the Saur Revolution and the establishment of the Democratic Republic of Afghanistan, Najibullah was a low-profile bureaucrat. He was sent into exile as Ambassador to Iran during Hafizullah Amin's rise to power. He returned to Afghanistan following the Soviet intervention which toppled Amin's rule and placed Babrak Karmal as head of the state, the party and the government. During Karmal's rule, Najibullah became head of the KHAD, the Afghan equivalent of the Soviet KGB. He was a member of the Parcham faction led by Karmal. During Najibullah's tenure as KHAD head, it became one of the most brutally efficient governmental organs. Because of this, he gained the attention of several leading Soviet officials, such as Yuri Andropov, Dmitriy Ustinov and Boris Ponomarev. In 1981, Najibullah was appointed to the PDPA Politburo. In 1985, Najibullah stepped down as the state security minister to focus on PDPA politics; he had been appointed to the PDPA Secretariat. Soviet General Secretary Mikhail Gorbachev, also the last Soviet leader, was able to get Karmal to step down as PDPA General Secretary in 1986, and replace him with Najibullah. For a number of months, Najibullah was locked in a power struggle against Karmal, who still retained his post of Chairman of the Revolutionary Council. Najibullah accused Karmal of trying to wreck his policy of National Reconciliation, a series of efforts by Najibullah to end the conflict.

The National Revolutionary Party (NRP; Dari: حزب انقلاب ملی, romanized: Hezb Enqilab Mili; Pashto: ملي انقلابي ګوند, romanized: Melli Enqelabi Gund), or National Revolution Party, was a political party in Afghanistan. The party was founded in 1974 by President Mohammad Daoud Khan, who had seized control of Afghanistan from his first cousin, King Mohammad Zahir Shah, in the mostly bloodless 1973 coup d'état.

The party was formed in an attempt by Daoud to garner support and grassroots backing for his republican regime. Daoud also intended the party to undermine support for the People's Democratic Party of Afghanistan (PDPA), who had actually helped him come to power in 1973. To this end, the party sought to be an umbrella organization for all of the factions of the progressive movement in Afghanistan. In order to help the party in its attempt to garner support, all other political parties were banned. Despite the party being anti-communist, Daoud demanded that members of the PDPA join the National Revolutionary Party and called for the dissolution of the Khalq and Parcham factions.
