Siaska Stevens was representing the
All People's Congress (APC) party in 1967 when he won the general elections and became the Prime Minister. In 1971, the parliamentary system was abolished in favor of a presidential system. This adoption of a new constitution made
Siaska Stevens the first executive President of Sierra Leone. Eventually, the APC would become the only recognized political party in the country. In 1978, a new constitution was adopted via referendum. This constitution replaced the multi-party system, instituting a single party state. Additionally, executive powers were increased and the presidential term limits increased from four to seven years. In October 1990, President Momoh appointed a thirty-five member National Constitutional Review Commission. This was in response to the growing opposition of a
one-party state. The review commission recommends constitutional changes, providing alternatives to the one-party state. ==List of presidents==
