Country on the southwest coast of West Africa
Sierra Leone (, , ; ), officially the Republic of Sierra Leone, is a country on the southwest coast of West Africa. It is bordered to the southeast by Liberia and by Guinea to the north. Its land area is . It has a tropical climate and environments ranging from savannas to rainforests. As of the 2023 census, Sierra Leone has a population of 8,908,040. Freetown is both its capital and its largest city. The country is divided into five administrative regions, which are further subdivided into 16 districts. 
Sierra Leone is a presidential republic, with a unicameral parliament and a directly elected president. It is a secular state. Its constitution provides for the separation of state and religion and freedom of conscience (which encompasses both freedom of thought and religion). Muslims constitute three-quarters of the population, and there is a significant Christian minority. Notably, religious tolerance is very high: it is both a social norm and part of the nation's cultural identity.
Sierra Leone's current territorial configuration was established in two phases: in 1808, the coastal Sierra Leone Colony was founded as a place to resettle returning Africans after the abolition of the slave trade; then in 1896, the inland Protectorate was created as a result of the Berlin Conference of 1884–1885. This led to the formal recognition of the territory as the Sierra Leone Colony and Protectorate. Sierra Leone attained independence from the United Kingdom in 1961 under the leadership of Prime Minister Sir Milton Margai of the Sierra Leone People's Party (SLPP). In 1971, under Prime Minister Siaka Stevens of the All People's Congress (APC), the country adopted a new constitution, transforming Sierra Leone into a presidential republic, with Stevens as the inaugural president. In 1978, Stevens declared the APC to be the sole legally recognized party. In 1985, he was succeeded by Joseph Saidu Momoh. Momoh's enactment of a new constitution in 1991 reintroduced a multi-party system. That same year, a protracted civil war broke out between the government and the Revolutionary United Front (RUF) rebel group. The conflict, characterized by multiple coups d'état, persisted for 11 years. Intervention by ECOMOG forces and later by the United Kingdom resulted in the defeat of the RUF in 2002, ushering in a period of relative stability. The two major political parties that remain are the APC and the SLPP.
Sierra Leone is a culturally diverse country, home to approximately 18 ethnic groups, with the Temne and Mende peoples being predominant. The Creole people, descendants of freed African-American, Afro-Caribbean slaves and liberated Africans, constitute about 1.2% of the population. English is the official language, while Krio is the lingua franca, spoken by 97% of the population. The country is rich with natural resources, notably diamonds, gold, bauxite and aluminium. As of the most recent survey in 2019, 59.2% of the population is affected by multidimensional poverty and an additional 21.3% vulnerable to it. Sierra Leone maintains membership in several international organizations, including the United Nations, African Union, Economic Community of West African States (ECOWAS), and the Commonwealth of Nations, among others.
Etymology.
Sierra Leone derives its name from the Lion Mountains near its capital, Freetown. Originally named (Portuguese for 'lioness mountains') by Portuguese explorer Pedro de Sintra in 1462, the modern name is derived from the Venetian spelling, which was introduced by Venetian explorer Alvise Cadamosto and subsequently adopted by other European mapmakers.
History.
Early history.
Sierra Leone's history is marked by continuous human habitation for at least 2,500 years, influenced by migrations from across Africa. The adoption of iron technology by the 9th century and establishment of agriculture by 1000 AD along the coast. Climate shifts over centuries altered the ecological zones, influencing migration and conquest dynamics.
The region's dense tropical rainforest and swamps, coupled with the presence of the tsetse fly which carried a disease fatal to horses and the zebu cattle used by the Mandé people, provided natural defenses against invasions by the Mandinka Empire and other African empires, and limited influence by the Mali Empire, preserving its indigenous cultures from external dominions. The introduction of Islam by Susu traders, merchants and migrants in the 18th century further enriched the culture, eventually establishing a strong foothold in the north. The conquest by Samory Touré in the northeast solidified Islam among the Yalunka, Kuranko and Limba people.
European trading.
The 15th century marked the beginning of European interaction with Sierra Leone, highlighted by Portuguese explorer Pedro de Sintra mapping the region in 1462 and naming it after the lioness mountains. This naming has been subject to historical reinterpretation, suggesting earlier European knowledge of the region. Following Sintra, European traders established fortified posts, engaging primarily in the slave trade, which shaped the socio-economic landscape significantly.
Traders from Europe, such as the Dutch Republic, England and France started to arrive in Sierra Leone and establish trading stations. These stations quickly began to primarily deal in slaves, who were brought to the coast by indigenous traders from interior areas, undergoing conflicts over territory. The Europeans made payments, called "Cole", for rent, tribute, and trading rights, to the king of an area. Local Afro-European merchants often acted as middlemen, the Europeans advancing them goods to trade to indigenous merchants, most often for slaves and ivory.
Early Portuguese interactions.
Portuguese traders were particularly drawn to the local craftsmanship in ivory, leading to a notable trade in ivory artifacts such as horns, Sapi Saltceller, and spoons. The Sapi people belonged to a cluster of people who spoke West Atlantic languages, living in the region of modern day Sierra Leone. There had already been a carving culture established in the area prior to Portuguese contact and many travelers to Sierra Leone initially impressed with their carving skills took local ivory horns back to Europe. One notable description at the beginning of the 16th century, by Pacheco noted that: in this country [Sierra Leone] they make beautiful mats of palm-leaf and necklaces of ivory [...]: In this land they make ivory necklaces more delicately carved than in any other country, also very fine and beautiful mats of palm-leaf, which are call 'bicas' [which are] very beautiful and good.
Black Poor of London.
In the late 18th century, some African Americans who had fought for the British Crown during the American Revolutionary War were resettled in Sierra Leone, forming a community named Black Loyalists. This resettlement scheme was partly motivated by social issues in London, with the Sierra Leone Resettlement Scheme offering a new beginning for the Black Poor, though it was fraught with challenges.
Resettlement of Black Loyalists.
In the late 18th century, many African Americans claimed the protection of the British Crown. There were thousands of these Black Loyalists, people of African ancestry who joined the British military forces during the American Revolutionary War. Many had been slaves who had escaped to join the British, lured by promises of freedom (emancipation). Official documentation known as the "Book of Negroes" lists thousands of freed slaves whom the British evacuated from the nascent United States and resettled in colonies elsewhere in British North America.
Pro-slavery advocates accused the Black Poor of being responsible for a large proportion of crime in 18th century London. While the broader community included some women, the Black Poor seems to have exclusively consisted of men, some of whom developed relationships with local women and often married them. Slave owner Edward Long criticized marriage between black men and white women. However, on the voyage between Plymouth, England and Sierra Leone, 70 European girlfriends and wives accompanied the Black Poor settlers.
Many in London thought moving them to Sierra Leone would lift them out of poverty. The Sierra Leone Resettlement Scheme was proposed by entomologist Henry Smeathman and drew interest from humanitarians like Granville Sharp, who saw it as a means of showing the pro-slavery lobby that black people could contribute towards the running of the new colony. Government officials soon became involved in the scheme as well, although their interest was spurred by the possibility of resettling a large group of poor citizens elsewhere. William Pitt the Younger, prime minister and leader of the Tory party, had an active interest in the Scheme because he saw it as a means to repatriate the Black Poor to Africa, since "it was necessary they should be sent somewhere, and be no longer suffered to infest the streets of London".
Establishment of the Province of Freedom.
In January 1787, the "Atlantic" and the "Belisarius" set sail for Sierra Leone, but bad weather forced them to divert to Plymouth, during which time about 50 passengers died. Another 24 were discharged, and 23 ran away. Eventually, with more recruitment, 411 passengers sailed to Sierra Leone in April 1787. On the voyage between Plymouth and Sierra Leone, 96 passengers died.
In 1787 the British Crown founded a settlement in Sierra Leone in what was called the "Province of Freedom". About 400 black and 60 white colonists reached Sierra Leone on 15 May 1787. After they established Granville Town, most of the first group of colonists died, owing to disease and warfare with the indigenous African peoples (Temne), who resisted their encroachment. When the ships left them in September, they had been reduced to "276 persons, namely 212 black men, 30 black women, 5 white men and 29 white women".
The settlers that remained forcibly captured land from a local African chieftain, but he retaliated, attacking the settlement, which was reduced to a mere 64 settlers comprising 39 black men, 19 black women, and six white women. Black settlers were captured by unscrupulous traders and sold as slaves, and the remaining colonists were forced to arm themselves for their own protection. The 64 remaining colonists established a second Granville Town.
Nova Scotians.
Following the American Revolution, some Black Loyalists from Nova Scotia, Canada, were relocated to Sierra Leone, founding Freetown and contributing significantly to the Krio people and Krio language that would come to define the region.
Following the American Revolution, more than 3,000 Black Loyalists had also been settled in Nova Scotia, where they were finally granted land. They founded Birchtown, but faced harsh winters and racial discrimination from nearby Shelburne. Thomas Peters pressed British authorities for relief and more aid; together with British abolitionist John Clarkson, the Sierra Leone Company was established to relocate Black Loyalists who wanted to take their chances in West Africa. In 1792 nearly 1,200 persons from Nova Scotia crossed the Atlantic to build the second (and only permanent) Colony of Sierra Leone and the settlement of Freetown on 11 March 1792. In Sierra Leone they were called the Nova Scotian Settlers, the "Nova Scotians", or the "Settlers". Clarkson initially banned the survivors of Granville Town from joining the new settlement, blaming them for the demise of Granville Town. The Settlers built Freetown in the styles they knew from their lives in the American South; they also continued American fashion and American manners. In addition, many continued to practise Methodism in Freetown.
In the 1790s, the Settlers, including adult women, voted for the first time in elections. In 1792, in a move that foreshadowed the women's suffrage movements in Britain, the heads of all households, of which a third were women, were given the right to vote. Black settlers in Sierra Leone enjoyed much more autonomy than their white equivalent in European countries. Black migrants elected different levels of political representatives, 'tithingmen', who represented each dozen settlers and 'hundreders' who represented larger amounts. This sort of representation was not available in Nova Scotia. The initial process of society-building in Freetown was a harsh struggle. The Crown did not supply enough basic supplies and provisions and the Settlers were continually threatened by illegal slave trading and the risk of re-enslavement.
Jamaican Maroons and Liberated Africans.
The Sierra Leone Company, controlled by London investors, refused to allow the settlers to take freehold of the land. In 1799 some of the settlers revolted. The Crown subdued the revolt by bringing in forces of more than 500 Jamaican Maroons, whom they transported from Cudjoe's Town (Trelawny Town) via Nova Scotia in 1800. Led by Colonel Montague James, the Maroons helped the colonial forces to put down the revolt, and in the process the Jamaican Maroons in Sierra Leone secured the best houses and farms.
On 1 January 1808, Thomas Ludlam, the Governor of the Sierra Leone Company and a leading abolitionist, surrendered the company's charter. This ended its 16 years
