The Constitution of Liberia is the supreme law of the Republic of Liberia. The current constitution, which came into force on 6 January 1986, replaced the Liberian Constitution of 1847, which had been in force since the independence of Liberia. Much like the 1847 Constitution, the Constitution creates a system of government heavily modeled on the Federal Government of the United States.

Samuel Kanyon Doe was a Liberian politician who served as the 21st President of Liberia from 1986 to 1990. He ruled Liberia as Chairman of the People's Redemption Council (PRC) from 1980 to 1986 and then as president from 1986 to 1990.
