This article on the History of Afghanistan since 1992 covers the time period from the fall of the Najibullah government in 1992 to the ongoing American military presence in Afghanistan.
After the Soviets withdrew completely from Afghanistan in February 1989, fighting between the communist backed government and mujahideen continued. With material help from the Soviets, Mohammad Najibullah's government survived, but after the collapse of the Soviet Union in 1991, it was overthrown on April 18, 1992. The forces of Abdul Rashid Dostum surrendered to Ahmed Shah Massoud and Kabul was left without defenses and soon fell to Massoud, at the time Doustum had 1500 militia in Kabul airport.
Seeking to resolve these differences, the leaders of the Peshawar-based mujahideen groups established an interim Jamiat-e Islami in mid-April to assume power in Kabul. Moderate leader Prof. Sibghatullah Mojadeddi was to chair the council for 2 months, after which a 10-member leadership council composed of mujahideen leaders and presided over by the head of the Jamiat-i-Islami, Prof. Burhanuddin Rabbani, was to be set up for 4 months. During this 6-month period, a Loya Jirga, or grand council of Afghan elders and notables, would convene and designate an interim administration which would hold power up to a year, pending elections.
But in May 1992, Rabbani prematurely formed the leadership council, undermining Mojaddedi's fragile authority. On June 28, 1992, Mojaddedi surrendered power to the Leadership Council, which then elected Rabbani as President. Nonetheless, heavy fighting broke out in August 1992 in Kabul between forces loyal to President Rabbani and rival factions, particularly those who supported Gulbuddin Hekmatyar's Hezb-i-Islami. After Rabbani extended his tenure in December 1992, fighting in the capital flared up in January and February 1993. The Islamabad Accord, signed in March 1993, which appointed Hekmatyar as Prime Minister, failed to have a lasting effect. A follow-up agreement, the Jalalabad Accord, called for the militias to be disarmed but was never fully implemented. Through 1993, Hekmatyar's Hezb-i-Islami forces, allied with the Shi'a Hezb-i-Wahdat militia, clashed intermittently with Rabbani and Massoud's Jamiat forces. Cooperating with Jamiat were militants of Sayyaf's Ittehad-i-Islami and, periodically, troops loyal to ethnic Uzbek strongman Abdul Rashid Dostam. On January 1, 1994, Dostam switched sides, precipitating large scale fighting in Kabul and in northern provinces, which caused thousands of civilian casualties in Kabul and elsewhere and created a new wave of displaced persons and refugees. The country sank even further into anomie, forces loyal to Rabbani and Masud, both ethnic Tajiks, controlled Kabul and much of the northeast, while local warlords exerted power over the rest of the country.
