How were martial law and the suspension of the writ of habeas corpus used to stifle dissent?

Martial law and the suspension of the writ of habeas corpus were employed by governments to suppress dissent by allowing for the detention of individuals without formal charges or legal recourse. This created an atmosphere of fear, as dissenters could be arrested without trial, undermining civil liberties and stifling opposition. The measures often targeted activists, political opponents, and anyone perceived as a threat to the regime, effectively silencing voices of dissent and curtailing public protests. By concentrating power in the hands of the military or executive authorities, these actions ensured that any organized resistance was quickly quelled.
