Sierra Leone ([sieɪrə liˈoːn]), officially the Republic of Sierra Leone, is a country in West Africa. It is bordered by Guinea in the north, Liberia in the southeast, and the Atlantic Ocean in the southwest. Sierra Leone covers a total area of 71,740 km2 (27,699 sq mi) [4] and has a population estimated at 6.4 million. The country is a constitutional republic comprising three provinces and the Western Area, which are further divided into fourteen districts.

The country has a tropical climate, with a diverse environment ranging from savannah to rainforests.[5] Freetown is the capital, largest city and economic center.[4]. English is the official language,[6] spoken at schools, government administration and by the media. However, the Krio language (a language derived from English and several African languages and native to the Sierra Leone Krio people) is the most widely spoken language in virtually all parts of the country. The Krio language is spoken by 97% of the country’s population[2] and unites all the different ethnic groups, especially in their trade and interaction with each other.[1] Despite its common use throughout the country, the Krio language has no official status. In December 2002, Sierra Leone’s President Ahmad Tejan Kabbah named Bengali as an “official language” in recognition of the work of 5,300 troops from Bangladesh in the peace-keeping force.[7][8]

Sierra Leone is very rich in minerals and has relied on mining, especially diamonds, for its economic base. The country is among the top 10 diamond producing nations in the world, and mineral exports remain the main foreign currency earner. Sierra Leone also claims to be home to the third largest natural harbour in the world, the Queen Elizabeth II Quay (also known as the QE II Quay and locally as the Deep Water Quay or Government Warf)[9][10].

Early inhabitants of Sierra Leone included the Sherbro, Temne and Limba, and Tyra [disambiguation needed] peoples, and later the Mende,[11] who knew the country as Romarong, and the Kono who settled in the East of the country.[12] In 1462, it was visited by the Portuguese explorer Pedro da Cintra, who gave it its name Serra de Leão, meaning ‘Lion Mountains’.[13][14] Sierra Leone later became an important centre of the transatlantic trade in slaves until 1792 when Freetown was founded by the Sierra Leone Company as a home for formerly enslaved African Americans.[15] In 1808, Freetown became a British Crown Colony, and in 1896, the interior of the country became a British Protectorate;[12] in 1961, the two combined and gained independence.

Over two decades of government neglect of the interior followed by the spilling over of the Liberian conflict into its borders eventually led to the Sierra Leone Civil War,[16] which began in 1991 and was resolved in 2000 after the struggling Nigerian led United Nations troops were heavily reinforced by a British force spearheaded by 42 Commando of the Royal Marines as well as several British Army units. The arrival of this force in what was codenamed OPERATION PALLISER resulted in the defeat of rebel forces and restored the civilian government elected in 1998 to Freetown. Since then, almost 72,500 former combatants have been disarmed[17] and the country has reestablished a functioning democracy.[2] The Special Court for Sierra Leone was set up in 2002 to deal with war crimes and crimes against humanity committed since 1996.[18]

Sierra Leone is the second lowest ranked country on the Human Development Index and seventh lowest on the Human Poverty Index, suffering from endemic corruption[19] and suppression of the press.[20]
