Across 25 "native states", many sultanates were overthrown and mass killing of members of the aristocratic families were performed by armed pergerakan groups. To the opportunistic pergerakan militants, the revolutionary movement was seen as one of the means for East Sumatra to be freed from colonial overlordship and to join the larger Indonesian National Revolution. Participants of the revolution were believed to be provoked by leaders to kill aristocrats and create violence.
