Soviet–Afghan War

The Soviet–Afghan War was a conflict wherein insurgent groups (known collectively as the Mujahideen), as well as smaller Maoist groups, fought a nine-year guerrilla war against the Soviet Army and the Democratic Republic of Afghanistan government throughout the 1980s, mostly in the Afghan countryside. The Mujahideen were variously backed primarily by the United States, Pakistan, Iran, Saudi Arabia, China, and the United Kingdom; the conflict was a Cold War-era proxy war. Between 562,000 and 2,000,000 civilians were killed and millions of Afghans fled the country as refugees, mostly to Pakistan and Iran.
The foundations of the conflict were laid by the Saur Revolution, a 1978 coup wherein Afghanistan’s communist party took power, initiating a series of radical modernization and land reforms throughout the country. These reforms were deeply unpopular among the more traditional rural population and established power structures. The repressive nature of the “Democratic Republic”, which vigorously suppressed opposition and executed thousands of political prisoners, led to the rise of anti-government armed groups; by April 1979, large parts of the country were in open rebellion.
