One of the Stasi's main tasks was spying on the population, primarily through a vast network of citizens turned informants, and fighting any opposition by overt and covert measures, including hidden psychological destruction of dissidents (Zersetzung, literally meaning "decomposition"). It arrested 250,000 people as political prisoners during its existence.[
