Shortly after Bhutto completed her studies in 1977 and returned to Pakistan, her father was deposed by Gen. Mohammad Zia-ul-Haq, who then made himself the chief martial-law administrator. After her father’s execution in 1979, Bhutto became the titular head of her father’s party, the Pakistan People’s Party (PPP), and endured frequent house arrest from 1979 to 1984. In exile from 1984 to 1986, she returned to Pakistan after the lifting of martial law and soon became the foremost figure in the political opposition to Zia.
