The first president of Bangladesh, Sheikh Mujibur Rahman, and most of his family were killed during the early hours of 15 August 1975 by a group of young Bangladesh Army personnel who invaded his Dhanmondi 32 residence as part of a coup d'état. Minister of Commerce Khondaker Mostaq Ahmad immediately took control of the government and proclaimed himself president. The assassination marked the first direct military intervention in Bangladesh's civilian administration-centric politics. 15 August is National Mourning Day, an official national holiday.
