During Martial Law years in the Philippines, President Ferdinand Marcos initially ruled effectively during his first term from 1965-1969, increasing infrastructure development and modernizing the military. However, growing unrest due to a communist insurgency, student protests, and rising crime led Marcos to declare Martial Law in 1972, suspending civil liberties. Martial Law allowed Marcos to rule by decree and arrest opponents until 1981, though economic troubles emerged in its later years as foreign debt mounted and cronyism impacted industries. Martial Law was formally lifted in January 1981 ahead of the country's first election in over a decade.
