In late December 1979, the Soviet Union launched an invasion of Afghanistan, deploying troops to support the Afghan communist government in its conflict against anti-communist Muslim guerrillas during the Afghan War (1978–1992).
This intervention marked the beginning of a prolonged and costly conflict, with Soviet forces remaining in the country until mid-February 1989.
The war soon reached a stalemate. Over 100,000 Soviet troops maintained control over urban centers, major towns, and key garrisons, while the mujahideen operated freely in the rural countryside.
Athough employing various strategies to suppress the insurgency, including large-scale assaults, the Soviets were unable to decisively defeat the guerrillas.
In an effort to weaken their opposition, the Soviets targeted civilian populations, bombing and depopulating rural areas.
These tactics triggered a humanitarian crisis, with millions fleeing their homes. By 1982, approximately 2.8 million Afghans had sought refuge in Pakistan, and another 1.5 million had crossed into Iran.
The mujahideen, aided by the United States’ supply of shoulder-fired antiaircraft missiles, managed to counter Soviet air superiority, further prolonging the conflict.
As the war dragged on, it became a severe strain on the Soviet Union, which was already grappling with internal challenges by the late 1980s.
The conflict claimed the lives of around 15,000 Soviet troops and left many more wounded. Athough their efforts, the Soviets failed to establish a stable, pro-communist regime in Afghanistan.
In 1988, under mounting pressure, the Soviet Union signed an accord with the United States, Pakistan, and Afghanistan, agreeing to withdraw its forces. This withdrawal was completed on February 15, 1989, leaving Afghanistan to revert to a nonaligned status.
The war left a profound and lasting impact on Afghanistan, reshaping its society and introducing a pervasive culture of guns, drugs, and terrorism.
Traditional power structures were dismantled, giving way to the rise of powerful Mujahideen militias.
The militarization transformed the society in the country, leading to heavily armed police, private bodyguards, and openly armed civil defense groups becoming the norm in Afghanistan both during the war and decades thereafter.
The war also altered the ethnic balance of power in the country.
While Pashtuns were historically politically dominant since the modern foundation of the Durrani Empire in 1747, many of the well-organized pro-Mujahideen or pro-government groups consisted of Tajiks, Uzbeks and Hazaras.
With Pashtuns increasingly politically fragmented, their influence on the state was challenged.
Scholars Rafael Reuveny and Aseem Prakash argue that the Soviet-Afghan War played a significant role in the eventual dissolution of the Soviet Union.
They highlight how the conflict damaged the reputation of the Red Army as an unbeatable force, eroded the legitimacy of the Soviet regime, and spurred the emergence of new political dynamics.
However, the financial burden of the war was relatively modest when compared to the Soviet Union’s other obligations.
The CIA estimated in 1987 that the war accounted for only about 2.5% of the USSR’s annual military expenditures.
Historian Sergey Radchenko supports this view, noting that there is no evidence to suggest the war caused financial insolvency for the Soviet Union.
Between 1984 and 1987, the USSR spent approximately $7.5 billion on the conflict—a minor figure when weighed against its annual military budget of roughly $128 billion.
The eventual decision to withdraw from Afghanistan stemmed from a combination of political considerations rather than purely economic ones.
Historians Stephen Kotkin and Vladislav Zubok, in their studies on the Soviet Union’s collapse, emphasize domestic factors as the primary drivers of its downfall, mentioning the Afghanistan war only briefly as a contributing factor.
