The dictatorship of Philippine President Ferdinand E. Marcos in the 1970s and 1980s is historically remembered for its record of human rights abuses, particularly targeting political opponents, student activists, journalists, religious workers, farmers, and others who fought against the Marcos dictatorship. Based on the documentation of Amnesty International, Task Force Detainees of the Philippines, and similar human rights monitoring entities, historians believe that the Marcos dictatorship was marked by 3,257 known extrajudicial killings, 35,000 documented tortures, 77 'disappeared', and 70,000 incarcerations.
