Movement Against Tyranny

The Movement Against Tyranny, or MAT, is a Philippine movement that seeks to protest alleged acts of tyranny by the administration of Philippine President Rodrigo Duterte. It was launched on August 28, 2017, at the Maryhill School of Theology in Quezon City in the wake of the killing of 17-year-old Kian delos Santos.

The group's convenors include Congress Representative Antonio Tinio, former senator Rene Saguisag, former representatives Erin Tanada and Neri Colmenares, Bishop Broderick Pabillo, and Sister Mary John Mananzan. The group also includes University of the Philippines (UP) Chancellor Michael Tan, and journalist Vergel Santos of the Center for Media Freedom and Responsibility.
