Martial law in the Philippines (Filipino: Batas Militar sa Pilipinas) refers to the various historical instances in which the Philippine head of state placed all or part of the country under military control - most prominently during the administration of Ferdinand Marcos, but also during the Philippines' colonial period, during the second world war, and more recently on the island of Mindanao during the administrations of Gloria Macapagal Arroyo and Rodrigo Duterte. The alternative term "Martial Law Era" as applied to the Philippines is typically used to describe the Marcos martial law period specifically.
