When the PKI supported unilateral land seizures, local PNI members attacked the PKI. On 30 September 1965, a coup attempt took place that was subsequently blamed on the PKI. In the aftermath of this, the PNI, which was seen as a PKI-collaborator, faced strong pressure from the army to purge its left wing and pro-PKI faction, led by party chairman Ali Sastroamidjojo and Surachman.
