Ferdinand Marcos Sr. was a Filipino politician who served as the 10th President of the Philippines from 1965 to 1986. He is known for declaring martial law in 1972, which allowed him to rule by decree and suppress dissent. His administration was marked by significant infrastructure projects but also widespread corruption and human rights abuses. Marcos was ousted from power during the People Power Revolution in 1986, a peaceful uprising that led to his exile in Hawaii. His legacy remains controversial, with supporters praising his economic initiatives and critics condemning his authoritarian rule and the impact of his policies on the Filipino people.
