Afghan Civil War (1989–1992)
The Ittehad-e Islami group was led by Abdul Rasul Sayyaf, a Wahhabite military leader. This group was mainly supported and assisted by Saudi Arabia. Just like the rivalry between Hezb-e Islami and Jamiat-e Islami, the Ittehad-e Islami group also had an opponent in the shared fight against the communists: the smaller mujahideen group of Abdul Ali Mazari called Hezb-e Wahdat, which was supported by Iran. This rivalry existed because Saudi Arabia and Iran were in competition for regional domination.
