The most serious attempted coup d'état against the government of Philippine President Corazon Aquino was staged beginning December 1, 1989, by members of the Armed Forces of the Philippines belonging to the Reform the Armed Forces Movement (RAM) and soldiers loyal to former President Ferdinand Marcos. Metro Manila was shaken by this Christmas-time coup, which almost seized the Malacañang Palace. It was completely defeated by the Philippine government by December 9, 1989.
