Mohammad Najibullah
On 8 March 1990, Shahnawaz Tanai and his Army personnel with the help of mujahideen commander, Gulbuddin Hekmatyar launched a coup against the then Russian-backed President Mohammad Najibullah. As Najibullah was transferring all the privileges of the Army to the tribal militias and in particular to his special guard, this policy intensified Tanai for which he launched the coup.
