The Afghan conflict (Pashto: دافغانستان جنګونه; Farsi/Dari: درگیری افغانستان) is the series of events that have kept Afghanistan in a near-continuous state of armed conflict since the 1970s. Early instability followed the collapse of the Kingdom of Afghanistan in the largely non-violent 1973 coup d'état, which deposed Afghan monarch Mohammad Zahir Shah in absentia, ending his 40-year-long reign. With the concurrent establishment of the Republic of Afghanistan, headed by Mohammad Daoud Khan, the country's relatively peaceful and stable period in modern history came to an end. However, all-out fighting did not erupt until after 1978, when the Saur Revolution violently overthrew Khan's government and established the Democratic Republic of Afghanistan. Subsequent unrest over the radical reforms that were being pushed by the then-ruling People's Democratic Party of Afghanistan (PDPA) led to unprecedented violence, prompting a large-scale pro-PDPA military intervention by the Soviet Union in 1979. In the ensuing Soviet–Afghan War, the anti-Soviet Afghan mujahideen received extensive support from Pakistan, the United States, and Saudi Arabia in a joint covert effort that was dubbed Operation Cyclone.
Although the Soviets withdrew from Afghanistan in 1989, the various mujahideen factions continued to fight against the PDPA government, which collapsed in the face of the Peshawar Accord in 1992. However, the Peshawar Accord failed to remain intact in light of the mujahideen's representatives' inability to reach an agreement on a power-sharing coalition for the new government, triggering a multi-sided civil war between them. By 1996, the Taliban, supported by Pakistan's Inter-Services Intelligence, had seized the capital city of Kabul in addition to approximately 90% of the country, while northern Afghanistan remained under the authority of the anti-Taliban Northern Alliance. During this time, the Northern Alliance's Islamic State of Afghanistan enjoyed widespread international recognition and was represented at the United Nations, as opposed to the Taliban's Islamic Emirate of Afghanistan which only received diplomatic recognition from three nations. Despite the fall of Kabul to the Taliban, the Northern Alliance continued to resist in another civil war for the next five years.
After the September 11 attacks against the United States, which were carried out by the Afghanistan-based group al-Qaeda, the Taliban refused demands by the Bush administration to extradite al-Qaeda leader Osama bin Laden. This prompted the American-led invasion of Taliban-controlled Afghanistan, which bolstered the Northern Alliance by toppling the Islamic Emirate and installing the Afghan Transitional Authority in 2002. The invasion triggered the 20-year-long War in Afghanistan, in which NATO and NATO-allied countries fought alongside the nascent Islamic Republic of Afghanistan to combat the Taliban insurgency. During the Battle of Tora Bora, the American-led military coalition failed to capture bin Laden, who subsequently relocated to Pakistan and remained there until he was killed by U.S. SEAL Team Six in Abbottabad in 2011. Nonetheless, the fighting in Afghanistan continued, eventually leading to the 2020–2021 American withdrawal and ultimately ending with the 2021 Taliban offensive, which led to the re-establishment of the present-day Islamic Emirate.
Though the country-wide war ended in 2021, clashes and unrest currently persist in some parts of Afghanistan due to the ISIS–Taliban conflict and the anti-Taliban Republican insurgency. Additional cross-border fighting between Afghanistan and Pakistan has taken place since 2021, due to the former's continued support for the Pakistani Taliban. As of 2026, the collapsed Islamic Republic of Afghanistan remains the internationally recognized government of the country.

Afghan Civil War (1989–1992): Continuation of the conflict between the Afghan government and the Afghan mujahideen but without the involvement of Soviet forces. The Soviet Union continued to financially support the Afghan government in its fight and, likewise, mujahideen factions continued to receive support from the United States and Pakistan. The Democratic Republic of Afghanistan survived until the Battle of Kabul, during which the mujahideen established the Islamic State of Afghanistan (ISA).
Afghan Civil War (1992–1996): Began when various mujahideen groups withdrew support from and began fighting against the ISA, including Hezb-e Islami Gulbuddin, later largely replaced by the Taliban and al-Qaeda (all of whom were supported by Pakistan), Hezb-e Wahdat (who were supported by Iran), and Junbish-i Milli Islami (who were supported by Uzbekistan). Mujahideen loyal to the Islamic State of Afghanistan received support from Saudi Arabia. Ended with the Taliban seizing control of Kabul and most of the country in 1996, establishing the first Islamic Emirate of Afghanistan (IEA).
Afghan Civil War (1996–2001): Continuation of the previous phase of the war between militias loyal to either the ISA or the Taliban-ruled IEA. ISA loyalists reorganized into the Northern Alliance, including Hezb-e Wahdat and Junbish-i Milli Islami, who previously opposed the ISA. During the war, al-Qaeda stepped up its terrorist attacks against the United States, culminating in the September 11 attacks, after which the IEA lost almost all international support and diplomatic recognition from Pakistan, Saudi Arabia, and the United Arab Emirates.
Islamic State–Taliban conflict (2015–present): Began in 2015, during the post-9/11 war, as Taliban dissident groups organized into the local branch of the Islamic State (not to be confused with the former Islamic State of Afghanistan). The group attacked the Taliban as well as NATO troops, but primarily targeted civilians. The insurgency is ongoing.
Republican insurgency in Afghanistan (2021–present): Began in 2021 when the remaining forces loyal to the fallen Islamic Republic reorganized into the National Resistance Front of Afghanistan in the Panjshir Valley. Despite having international recognition as the legitimate government of Afghanistan, the National Resistance Front has received no foreign support. Taliban forces captured the Panjshir Valley in September 2021, and leaders of the National Resistance Front fled to Tajikistan. Fighting is ongoing between the newly organized military of the Taliban and the small, scattered holdouts of the National Resistance Front in Panjshir Province and Baghlan Province.
By 2014, adding different estimates of casualties for some of these individual conflicts together, 1,405,111 to 2,084,468 people had been killed over the duration of the Afghanistan conflict.
Shah was overthrown by his cousin Mohammad Daoud Khan in July 1973, after discontent with the monarchy grew in the urban areas of Afghanistan. The country had experienced several droughts, and charges of corruption and poor economic policies were leveled against the ruling dynasty. Khan abolished the monarchy and declared the Republic of Afghanistan, and he became the first president of Afghanistan. He was supported by a faction of the People's Democratic Party of Afghanistan (PDPA), Afghanistan's communist party, which was founded in 1965 and enjoyed a strong relationship with the Soviet Union. In The Rise of the Taliban in Afghanistan: Mass Mobilization, Civil War, and the Future of the Region, Neamatollah Nojumi writes: "The establishment of the Republic of Afghanistan increased the Soviet investment in Afghanistan and the PDPA influence in the government's military and civil bodies."
In 1976, alarmed by the growing power of the PDPA and the party's strong affiliation with the Soviet Union, Khan tried to scale back the PDPA's influence. He dismissed PDPA members from their government posts, appointed conservative elements instead and finally announced the dissolution of the PDPA, arresting senior party members.
Democratic Republic of Afghanistan
On 27 April 1978, the PDPA and military units loyal to the PDPA revolted and killed Khan, his immediate family and bodyguards in a violent coup during the battle to seize control of the capital, Kabul, in the Saur Revolution. As the PDPA had chosen a weekend holiday to conduct the coup, when many government employees were having a day off, Khan was not able to fully activate the well-trained armed forces which remained loyal to him to counter the coup.
The PDPA's Democratic Republic
Khalqists vs. Parchamites
The PDPA formed a new government through a 'revolutionary council', which attempted to balance the two major competing factions within itself—the more radical and revolutionary Khalq and the more moderate and reformist Parcham. The Khalqist wing, led by the charismatic Nur Muhammad Taraki, who became the new chairman, gained supremacy in the aftermath of the revolution and adopted a program of land reform, abolition of feudal and tribal structures and equality for women. The council also prefixed the term "Democratic" to the country's Daoud-era name, making it the "Democratic Republic of Afghanistan." Though these reforms were supported by the army and city-dwelling population, they opposed the very traditional, religious and tribal customs of rural Afghanistan, which in turn led to strong rural and clerical opposition to the government and various anti-government uprisings. Around this time, the party came to be influenced by Hafizullah Amin, who undermined Taraki despite being a fellow Khalqist, purged Parchamites from the party and began ruthlessly cracking down on political opposition. Therefore, a hostile doctrine against any political dissent was adopted, whether inside or outside the party. Taraki, who had ruled for only about a year, was assassinated by Amin, who took over formal leadership of the country.
Mass executions
Amin was known for his independent and nationalist inclinations and was also seen by many as a ruthless leader. He has been accused of killing tens of thousands of Afghan civilians at Pul-e-Charkhi and other national prisons while cracking down on both the opposition and the Parchamites: 27,000 politically motivated executions reportedly took place at Pul-e-Charkhi prison alone. Afghans generally held Amin personally responsible for most of the repression, while the Soviet Union considered his government illegitimate, discredited and doomed to collapse in a civil war.
Soviet pro-Parchamite intervention
The Soviet Union secured an alliance with the more moderate Babrak Karmal and his Parchamite faction, invading Afghanistan on 24 December 1979 and originally meeting only limited resistance. Amin was deposed from power almost immediately, as he and 200 of his guards were killed during Operation Storm-333 on 27 December by Soviet ArmySpetsnaz, replaced by Karmal. After deployment into Afghanistan, Soviet forces, whom the locals dubbed Shuravi, along with government forces would begin to engage in a protracted counterinsurgency war against a wide coalition of various anti-government insurgent forces, who in turn styled themselves as mujahideen—Islamic holy warriors.
Soviet–Afghan War
Leadership of Babrak Karmal
Karmal declared a general amnesty for people imprisoned during Taraki and Amin's rule and restored the Afghan national symbols in place of the Khalqist red flag. He also granted several concessions to religious leaders and at least partially restored property seized during the original Khalqist land reform. However, this did not satisfy the opposition, as they considered his ascension to power during the Soviet intervention to be a mark that he would rule as a "Soviet puppet", thus continuing their insurgency against the government.
The Soviet government realized that a military solution to the conflict would require far more troops. Because of this they discussed troop withdrawals and searched for a political and peaceful solution as early as 1980, but they never took any serious steps in that direction until 1988. Early Soviet military reports confirm the difficulties the Soviet army had while fighting on the mountainous terrain, for which the Soviet army had no training. Parallels with the Vietnam War were frequently referred to by Soviet army officers.
Leadership of Mohammad Najibullah
Policy failures and the stalemate that ensued after the Soviet intervention led the Soviet leadership to become highly critical of Karmal's leadership. Under Mikhail Gorbachev, the Soviet Union was able to depose Karmal and replace him with Mohammad Najibullah. Karmal's leadership was seen as a failure by the Soviet Union because of the rise of violence and crime during his administration. Najibullah, another Parchamite, attempted to end the insurgency through a policy of accommodation and power sharing known as the National Reconciliation. He reversed several of his predecessor's unpopular reforms, abolished the one-party system, reinstated Islam as the state religion (though still maintaining a fairly secular legal and political setup), replaced the Revolutionary Council with a republican presidency and bicameral parliament, removed communist symbols deemed "provocative" to the opposition from the country's national emblem, dropped the "Democratic" prefix from the country's name, offered amnesty to mujahideen fighters and called for a six-month ceasefire in which fighting would stop in exchange for political negotiations intended to create a coalition government between the PDPA and various rebel groups in an attempt to end the country's crisis.
