"The traditional
rivalry for power and influence between the Pashtun majority and the minority Persian (
Dari)-speaking ethnic groups of Afghanistan such as the
Tajiks,
Hazaras,
Uzbeks and
Turkmen, has often stirred anti-Pashtun sentiments among the latter. In 1975, an uprising broke out in
Panjsher Valley against the rule of Afghan prime minister and Pashtun nationalist
Daoud Khan, which was believed to have been "sparked by anti-Pashtun frustrations."
[1] The
Settam-e-Melli, led by Uzbek activist
Tahir Badakhshi, has been described as "an anti-Pashtun
leftist mutation."
[1] According to
Nabi Misdaq, the Settem-e-Melli "had an internal programme of provoking minorities to armed resurrection to stand up to Pashtuns."
[2] The
Shalleh-ye Javiyd, a Maoist political party founded in the 1960s that predominantly drew support from Shi'a Muslims and Hazaras, was also similarly opposed to Pashtun rule in Afghanistan.
[2]
However, Misdaq notes that these anti-Pashtun stances were usually engraved more in a "Shi'a-versus-Sunni
Afghan", "Dari-speaking-intellectuals-versus-Pashtun-rulers" and "majority-versus-minority" context rather than resentment on misrule or mistreatment by Pashtun kings and dynasties.
[2] This could be because Afghan dynasties such as the
Durrani Empire, although Pashtun by origin, had been considerably
Persianised and had even adopted the
Dari language over
Pashto; this cultural assimilation made the Durranis culturally familiar to Dari-speaking non-Pashtuns and neutralised any ethnic hegemony.

The
Rabanni government which ruled Afghanistan in the early and mid-1990s was viewed by the
Taliban as corrupt, anti-Pashtun and responsible for civil war"
