President of Afghanistan in the context of "Fall of Kabul (2021)"

The Islamic Republic of Afghanistan was a presidential republic in Afghanistan from 2004 to 2021. The state was established to replace the Afghan interim (2001–2002) and transitional (2002–2004) administrations, which were formed after the 2001 United States invasion of Afghanistan that had toppled the partially recognized Taliban-ruled Islamic Emirate of Afghanistan. However, on 15 August 2021, the country was recaptured by the Taliban, which marked the end of the 2001–2021 war, the longest war in US history. This led to the overthrow of the Islamic Republic, led by President Ashraf Ghani, and the reinstatement of the Islamic Emirate under the control of the Taliban, today the ruling government of Afghanistan. While the United Nations still recognizes the Islamic Republic as the legitimate government of Afghanistan, this toppled government controls no portion of the country. The US–Taliban deal, signed on 29 February 2020 in Qatar, was one of the critical events that caused the collapse of the Afghan National Security Forces (ANSF). Following the deal, the US dramatically reduced the number of air attacks and deprived the ANSF of a critical edge in fighting the Taliban insurgency, leading to the Taliban takeover of Kabul.

Following the September 11 attacks, the United States and several allies invaded Afghanistan, overthrowing the Taliban's first government (which had limited recognition) in support of the opposition Northern Alliance. Afterwards, a transitional government was formed under the leadership of Hamid Karzai. After the 2003 loya jirga, a unitary presidential Islamic republic was proclaimed under a new constitution, and Karzai was elected for a full term as president. Meanwhile, the US-led international coalition helped maintain internal security, gradually transferring the burden of defense to the Afghan Armed Forces after 2013–14.

Mohammad Daoud Khan, (18 July 1909 – 28 April 1978), also romanized as Daud Khan or Dawood 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 he himself was deposed in a coup and killed in the Saur Revolution.

Born into the Afghan royal family and addressed by the prefix "Sardar", Khan started as a provincial governor and later a military officer before being appointed as prime minister by his cousin, King Mohammad Zahir Shah, serving for a decade. Having failed to persuade the King to implement a one-party system, Khan overthrew the monarchy in a virtually bloodless coup with the backing of Afghan Army officers, and proclaimed himself the first president of the Republic of Afghanistan, establishing an autocratic one-party system under his National Revolutionary Party.

Kabul International Airport (IATA: KBL, ICAO: OAKB) is located in the northern part of Kabul, Afghanistan. It is one of the country's main international airports, capable of housing over a hundred military and civilian aircraft. It is currently operated by UAE-based GAAC Holding and Afghanistan's Ministry of Transport and Civil Aviation.

The airport was originally named as Khwaja Rawash Airport because it was built in the area named Khwaja Rawash. It was given the name Kabul Airport in 1960 after the Soviet Union built a terminal and a concrete runway. From 2014 to 2021, it was named Hamid Karzai International Airport in honor of former president Hamid Karzai. After the Taliban returned to power in 2021, the name was changed back to Kabul International Airport.

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.

The 2004 Constitution of Afghanistan was the supreme law of the Islamic Republic of Afghanistan, which lasted from 2004 to 2021. It served as the legal framework between the Afghan government and the Afghan citizens. Although Afghanistan (Afghan Empire) was made a state in 1747 by Ahmad Shah Durrani, the earliest Afghan constitutional movement began during the reign of Emir Abdur Rahman Khan in the 1890s followed by the drafting in 1922 of a constitution. The 1964 Constitution of Afghanistan transformed Afghanistan into a modern democracy.

The constitution was approved by the consensus in January 2004 after the 2003 loya jirga. The Constitution consists of 162 articles and was officially signed by Hamid Karzai on January 26, 2004. It evolved out of the Afghan Constitution Commission mandated by the Bonn Agreement. The constitution provides for an elected President and National Assembly. The transitional government of interim president Hamid Karzai was put in place after the June 2002 loya jirga. The first presidential elections after the new constitution was in effect, took place in October 2004, and Karzai was elected to a five-year term. The first elections for the National Assembly were delayed until September 2005. The constitution was essentially abolished on August 15, 2021, with the overthrow and dissolution of the Islamic Republic of Afghanistan by the Taliban. In August 2022, it was confirmed to the public that Supreme Leader Hibatullah Akhundzada had earlier formally abolished the 2004 Constitution on his authority.

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.

Hamid Karzai (born 24 December 1957) is an Afghan politician who served as the seventh president of Afghanistan from 2002 to 2014, including as the first president of the Islamic Republic of Afghanistan from 2004 to 2014. He also served as chairman of the Afghan Interim Administration from 2001 to 2002.

Born in Kandahar, Karzai graduated from Habibia High School in Kabul and later received a master's degree from Himachal Pradesh University, Summerhill, Shimla, India, in the 1980s. He moved to Pakistan where he was active as a fundraiser for the Afghan mujahideen during the Soviet–Afghan War (1979–1989) and its aftermath. He briefly served as Deputy Foreign Minister in the Islamic State of Afghanistan government. In July 1999, Karzai's father was assassinated and Karzai succeeded him as head of the Popalzai tribe. In October 2001 the United States invasion of Afghanistan began and Karzai led the Pashtun tribes in and around Kandahar in an uprising against the Taliban; he became a dominant political figure after the removal of the Taliban regime in late 2001. During the December 2001 International Conference on Afghanistan in Germany, Karzai was selected by prominent Afghan political figures to serve a six-month term as chairman of the Interim Administration.

Burhanuddin Rabbani (20 September 1940 – 20 September 2011) was an Afghan politician and teacher who served as the sixth president of Afghanistan from 1992 to 1996, and again from November to December 2001 (in exile from 1996 to 2001).

Born in the Badakhshan Province, Rabbani studied at Kabul University and worked there as a professor of Islamic theology. He formed the Jamiat-e Islami at the university which attracted then-students Gulbuddin Hekmatyar and Ahmad Shah Massoud, both would eventually become the two leading commanders of the Afghan mujahideen in the Soviet–Afghan War from 1979. Rabbani was chosen to be the President of Afghanistan after the end of the former communist regime in 1992. Rabbani and his Islamic State of Afghanistan government was later forced into exile by the Taliban, and he then served as the political head of the Northern Alliance, an alliance of various political groups who fought against the Taliban regime in Afghanistan. During his time in the office, there were a lot of internal clashes between different fighting groups.

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.
