The Philippine Legislature was corrupt and impotent. Opponents of Marcos blocked the necessary legislation to implement his ambitious plans. Because of this, optimism faded early in his second term and economic growth slowed. Crime and civil disobedience increased. The Communist Party of the Philippines formed the New People's Army. The Moro National Liberation Front continued to fight for an independent Muslim nation in Mindanao. An explosion during the proclamation rally of the senatorial slate of the Liberal Party on August 21, 1971 prompted Marcos to suspend the writ of habeas corpus.
In Negros and central Philippines Communist guerrillas began fighting government forces and in the south in Mindanao Moro Islamic Liberation Front took up the fight.
