Soviet intervention in Afghanistan (1978–1992) a look back in to History
A search for Who are The Talibans Actually?.
President Ronald Reagan meeting with Afghan Mujahideen leaders in the Oval Office in 1983 After the Soviet Union intervened and occupied Afghanistan in 1979, Islamic mujahideen fighters engaged in war with those Soviet forces.
Most of the original Taliban leadership came from the same three southern provinces—Kandahar, Uruzgan and Helmand—and nearly all of them fought under one of the two main clerical resistance parties during the war against the Soviets: Hezb-e Islami (Khales) and Mohammad Nabi Mohammadi’s Harakat-I Ineqelab-ye Islami.
The Taliban fighting ranks were mostly filled with former veterans of the war against Soviet forces.
Nearly all of the Taliban's original leadership previously fought in the Soviet-Afghan War for either the Hezb-i Islami Khalis or Harakat-i Inqilab-e Islami factions of the Mujahideen.
Pakistan's President Muhammad Zia-ul-Haq feared that the Soviets were planning to also invade Balochistan, Pakistan, so he sent Akhtar Abdur Rahman to Saudi Arabia to garner support for the Afghan resistance against Soviet occupation forces.
A while later, the US CIA and Saudi Arabian General Intelligence Directorate (GID) funnelled funding and equipment through the Pakistani Inter-Service Intelligence Agency (ISI) to the Afghan mujahideen.
About 90,000 Afghans, including Mohammed Omar, were trained by Pakistan's ISI during the 1980s.
