Sierra Leone was a British Crown Colony from 1808 to April 27, 1961 when it achieved independence from Britain as Milton Margai became the country's first Prime Minister. From 1967 to 1985 Sierra Leone was a one party state, in which all other political parties were banned, under the rule of the country's first president Siaka Stevens. On 19 April 1971, Stevens" government abolished Sierra Leone's parliamentary government system and declared Sierra Leone a presidential republic. The current multiparty democratic constitution of Sierra Leone was adopted in 1991 by the government of President Joseph Saidu Momoh, Stevens" hand picked successor, just as the rebel group Revolutionary United Front, led by former imprisoned Sierra Leone army officer Foday Sankoh, launched a brutal civil war in the country.
On April 29, 1992, a group of Junior soldiers in the Sierra Leone Army lead by a 25 year old Captain Valentine Strasser overthrew President Momoh, and Sierra Leone was under Military rule from 1992 to 1996 during the civil war. Sierra Leone returned to a democratically elected government when the military Junta under Brigadier General Julius Maada Bio who had ousted Strasser in a coup in 1996, handed the presidency to Ahmad Tejan Kabbah of the SLPP after his victory in the 1996 Sierra Leone presidential election. However, on May 25, 1997, the Sierra Leone military overthrew President Kabbah in a coup and Major General Johnny Paul Koroma became the country's Head of State. However, in February 1998, a coalition of West African Ecowas armed forces led by Nigeria reinstated President Kabbah by military force, and the leaders of the coup were executed after they were sentenced to death by a Sierra Leone military court. In January 2002, President Kabbah announced the ending of the civil war with the help and support of Ecowas, the British government, the African Union, and the United Nations. Sierra Leone has had an uninterrupted democratic government from 1998 to present.

Although English is the official language, used in schools and government administration, Krio, an English-based creole, is the most widely spoken language across Sierra Leone. Spoken by 98% of the population, Krio unites all the ethnic groups in the country, especially in their trade and social interaction.
