Afghans in Pakistan are temporary residents from Afghanistan who are registered in Pakistan as refugees and asylum seekers. They fall under the jurisdiction of the United Nations High Commissioner for Refugees (UNHCR). Most of them were born and raised in Pakistan during the last four decades. Additionally, there are also Special Immigrant Visa applicants awaiting to immigrate to the United States.

The Soviet–Afghan War was a protracted armed conflict fought in the Soviet-controlled Democratic Republic of Afghanistan (DRA) from 1979 to 1989. The war was a major conflict of the Cold War as it saw extensive fighting between the DRA, the Soviet Union and allied paramilitary groups against the Afghan mujahideen and their allied foreign fighters. While the mujahideen were backed by various countries and organizations, the majority of their support came from Pakistan, the United States, the United Kingdom, China, Iran, and the Arab states of the Persian Gulf. The involvement of the foreign powers made the war a proxy war between the United States and the Soviet Union. Combat took place throughout the 1980s, mostly in the Afghan countryside. The war resulted in the deaths of approximately 3,000,000 Afghans, while millions more fled from the country as refugees; most externally displaced Afghans sought refuge in Pakistan and in Iran. Approximately 6.5% to 11.5% of Afghanistan's erstwhile population of 13.5 million people is estimated to have been killed over the course of the conflict. The Soviet–Afghan War caused grave destruction throughout Afghanistan and has also been cited by scholars as a significant factor that contributed to the dissolution of the Soviet Union, formally ending the Cold War.
