The 1979 Constitution of Nigeria was the supreme law governing Nigeria from 1979 to 1983. The constitution provided for a presidential system of government, with a head of state who is also the head of government. It also introduced the participation of women in politics by requiring that a minimum of 10% of elected officials at all levels of government be women. Additionally, the constitution emphasized the importance of fundamental human rights, such as freedom of speech and the right to a fair trial, and made all men equal before the law, regardless of their social status or background. However, the constitution did not provide for a House of Chiefs.
