Khalq in the context of "Operation Storm-333"

The Democratic Republic of Afghanistan, later known as the Republic of Afghanistan, was the Afghan state from 1978 to 1992. It was bordered by Pakistan to the east and south, by Iran to the west, by the Soviet Union to the north, and by China to the northeast. Established by the People's Democratic Party of Afghanistan (PDPA) following the Saur Revolution in April 1978, it came to rely heavily on the Soviet Union for financial and military assistance and was therefore widely considered to be a Soviet satellite state. The PDPA's rise to power is seen as the beginning of the ongoing Afghan conflict, and the majority of the country's years in existence were marked by the Soviet–Afghan War. It collapsed by the end of the First Afghan Civil War in April 1992, having lasted only four months after the dissolution of the Soviet Union.

The PDPA began ruling Afghanistan after ousting the unelected autocrat Mohammad Daoud Khan, who had become president by leading the 1973 Afghan coup d'état; he was succeeded by Nur Muhammad Taraki as the head of state and government on 30 April 1978. Both Taraki and his successor Hafizullah Amin, who had organized the Saur Revolution as the General Secretary of the PDPA, introduced several contentious reforms during their time in office, such as land and marriage reforms and an enforced policy of de-Islamization vis-à-vis the promotion of socialism. Amin, in particular, built upon Khan's reforms with even more radical legislation for Afghanistan's conservative Muslim society, such as universal education and equal rights for women. Soon afterwards, a power struggle began between two PDPA factions: the hardline Khalq, led by Taraki and Amin; and the moderate Parcham, led by Babrak Karmal. The Khalqists eventually emerged victorious and subsequently purged the bulk of the Parchamite ranks, while also exiling most of the prominent Parcham leaders to the Soviet Union and the Eastern Bloc.

The Northern Alliance, officially known as the National United Islamic Front for the Salvation of Afghanistan, was an Afghan military alliance of groups that operated between early 1992 and 2001 following the dissolution of the Soviet Union. It was formed by military leaders such as Ahmad Shah Massoud, Burhanuddin Rabbani, Abdul Rashid Dostum, Abdul Momim and Ali Mazari. It consisted mainly of ethnicities from northern Afghanistan, such as Tajiks, Uzbeks, Hazaras, and Turkmens, as opposed to the Pashtun-led Taliban. At that time, many non-Pashtun Northerners originally with the Republic of Afghanistan led by Mohammad Najibullah became disaffected with Pashtun Khalqist Afghan Army officers holding control over non-Pashtun militias in the North. The alliance's capture of Mazar-i-Sharif and more importantly the supplies kept there crippled the Afghan military and began the end of Najibullah's government. Following the collapse of Najibullah's government, the Alliance would fall with a second civil war breaking out. However, following the Taliban's takeover of Kabul and establishment of their Islamic Emirate of Afghanistan, the United Front was reassembled.

The Northern Alliance fought a defensive war against the Taliban regime. They received support from Iran, Russia, Tajikistan, Turkmenistan, the United States and Uzbekistan, while the Taliban were extensively backed by the Pakistan Army and Pakistan's Inter-Services Intelligence. By 2001, the Northern Alliance controlled less than 10% of the country, cornered in the north-east and based in Badakhshan province. The US invaded Afghanistan, providing support to Northern Alliance troops on the ground in a two-month war against the Taliban, which they won in December 2001. With the Taliban forced from control of the country, the Northern Alliance was dissolved as members and parties supported the new Afghan Interim Administration, with some members later becoming part of the Karzai administration.

Parcham (Pashto/Dari: پرچم, lit. 'banner' or 'flag') was the more moderate socialist faction of the People's Democratic Party of Afghanistan (PDPA) led by Afghan communist politician Babrak Karmal. It was later turned into the Watan (Homeland) Party of Afghanistan with a more Islamic outlook under Mohammed Najibullah. The faction was formed directly after the founding of the Party in 1965 following ideological splits in the PDPA. While the Parchamites stressed the need for swift social-economic reforms to achieve revolution, this was in direct contrast with their PDPA rivals, the Khalqists, who sought an immediate and violent overthrow of the government. Karmal believed that Afghanistan was not developed enough for a Leninist revolutionary approach and instead sought a patriotic and anti-imperialist united front to take the next steps toward revolution.

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.

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. The successful PDPA uprising resulted in the creation of a socialist Afghan government that was closely aligned with the Soviet Union, with Nur Muhammad Taraki serving as the PDPA's General Secretary of the Revolutionary Council. Saur (also rendered Sowr) is the Dari-language name for the second month of the Solar Hijri calendar, during which the events took place.

The uprising was ordered by PDPA member Hafizullah Amin, who would become a significant figure in the revolutionary Afghan government. At a press conference in New York City in June 1978, Amin claimed that the event was not a coup d'état, but rather a "popular revolution" carried out by the "will of the people" against Daoud's government. The Saur Revolution involved heavy fighting throughout Afghanistan and resulted in the deaths of as many as 2,000 military personnel and civilians combined. It remains a significant event in Afghanistan's history as it marked the beginning of decades of continuous conflict in the country.

Hafizullah Amin (Dari/Pashto: حفيظ الله امين;‎ 1 August 1929 – 27 December 1979) was an Afghan communist head of state, who served in that position for a little over three months, from September 1979 until his assassination. He organized the Saur Revolution of 1978 and co-founded the Democratic Republic of Afghanistan (DRA), ruling Afghanistan as General Secretary of the People's Democratic Party.

Born in the town of Paghman in Kabul Province, Amin studied at Kabul University and started his career as a teacher before he twice went to the United States to study. During this time, Amin became attracted to Marxism and became involved in radical student movements at the University of Wisconsin. Upon his return to Afghanistan, he used his teaching position to spread socialist ideologies to students, and he later joined the People's Democratic Party of Afghanistan (PDPA), a new far-left organization co-founded by Nur Muhammad Taraki and Babrak Karmal. He ran as a candidate in the 1965 parliamentary election but failed to secure a seat, but in 1969 became the only Khalqist elected to parliament, increasing his standing within the party.

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 1992–1996 Afghan Civil War, also known as the Second Afghan Civil War, took place between 28 April 1992 — the date a new interim Afghan government was supposed to replace the Republic of Afghanistan of President Mohammad Najibullah—and the Taliban's occupation of Kabul establishing the Islamic Emirate of Afghanistan on 27 September 1996.

The war immediately followed the 1989–1992 civil war with the mujahideen victory and dissolution of the Republic of Afghanistan in April 1992. The Hezb-e Islami Gulbuddin, led by Gulbuddin Hekmatyar and supported by Pakistan's Inter-Services Intelligence (ISI), refused to form a coalition government and tried to seize Kabul with the help of Khalqists. On 25 April 1992 fighting broke out between three, and later five or six, mujahideen armies. Alliances between the combatants were transitory throughout the war.
