As part of a Cold War strategy, in 1979 the United States government (under President Jimmy Carter and National Security Advisor Zbigniew Brzezinski) began to covertly fund and train anti-government Mujahideen forces through the Pakistani secret service known as Inter Services Intelligence (ISI). In order to bolster the local Communist forces, the Soviet Union—citing the 1978 Treaty of Friendship, Cooperation and Good Neighborliness that had been signed between the two countries—intervened on December 24, 1979. Over 100,000 Soviet troops took part in the invasion, who were backed by another 100,000 and plus pro-communist forces of Afghanistan. The Soviet occupation resulted in the killings of at least 600,000 to 2 million Afghan civilians. Over five million Afghans fled their country to Pakistan, Iran and other parts of the world. Faced with mounting international pressure and great number of casualties on both sides, the Soviets withdrew in 1989.

Following the removal of the Soviet forces, the US and its allies lost interest in Afghanistan and did little to help rebuild the war-ravaged country or influence events there. The USSR continued to support President Najibullah (former head of the Afghan secret service, KHAD) until 1992 when new Russian government refused to sell oil products to Najibullah regime.

Because of the fighting, a number of elites and intellectuals fled to take refuge abroad. This led to a leadership imbalance in Afghanistan. Fighting continued among the victorious Mujahideen factions, which gave rise to a state of warlordism. The most serious fighting during this period occurred in 1994, when over 10,000 people were killed in Kabul alone. It was at this time that the Taliban developed as a politico-religious force, eventually seizing Kabul in 1996. By the end of 2000 the Taliban had captured 95% of the country.

During the Taliban's seven-year rule, much of the population experienced restrictions on their freedom and violations of their human rights. Women were banned from jobs, girls forbidden to attend schools or universities. Those who resisted were punished instantly. Communists were systematically eradicated and thieves were punished by amputating one of their hands or feet.Meanwhile, the Taliban managed to nearly eradicate the majority of the opium production by 2001.
