Presidency of Ziaur Rahman
Ziaur Rahman's tenure as the President of Bangladesh started with his acquisition of the presidency from Abu Sadat Mohammad Sayem on 21 April 1977, after the latter resigned from his position on health grounds. Zia became the president of Bangladesh at a time when Bangladesh was suffering from a host of challenges that included low productivity, a food shortage that resulted in a famine in 1974, unsatisfactory economic growth, severe corruption and a polarized and turbulent political atmosphere after the assassination of Sheikh Mujibur Rahman and his family members in a coup that was followed by a series of counter-coups.
