Sierre Leone

Sierra Leone is a country in West Africa on the Atlantic coast between Guinea and Liberia. The country’s capital is Freetown, one of the world’s largest natural harbours. Sierra Leone is home to the Gola-Tiwai Complex, containing the Gola Rainforest National Park and the Tiwai Island Wildlife Sanctuary. A UNESCO World Heritage Site and biodiversity hotspot, the Gola-Tiwai Complex provides vital habitats and ecosystems to more than 1,000 plant species, 55 mammals and almost 450 birds. Despite the country’s carbon emissions being very low, Sierra Leone is ranked in the top 10% of countries vulnerable to the devastating effects of climate change.

Economy

The economic activity in Sierra Leone centres around two industries. The first is agriculture with many of the population engaged in subsistence agriculture. Villages in rural landscapes focus on rice farming, fishing and raising and herding cattle. The second is mining. Although mining provides a significant contribution to the national economy of Sierra Leone and employs a large segment of the population, private capital from Europe, Lebanon and India dominate the industry and participation by Sierra Leoneans is limited.

International foreign trade has expanded substantially since Sierra Leone gained independence in the early 1960s. Sierra Leone’s main exports are agricultural products and minerals including iron ore, titanium ore such as rutile, diamonds, rough wood and aluminium ore such as bauxite. The country’s main imports are machinery, vehicles, fuel and food products.

Ethnic groups and language

With a population of 9.1 million (as of 2025), Sierra Leone has a rich and diverse heritage. Archaeologists and historians have traced the very earliest inhabitants of the country back to 500BC with the settlement of the Bulom, Temne and Limba people, followed by subsequent sporadic immigration from Mande-speaking peoples including Vai, Loko and Mende. These communities organised themselves in small political units, known as independent kingdoms or chiefdoms.

Sierra Leone is today home to 18 ethnic groups. The two largest groups are the Mende, who mainly live in the east and south, and the Temne, who predominantly reside in the centre and northwest. Other groups include the Limba, Kuranko, Susu, Yalunka and Loko in the north; the Kono and Kisi in the east; the Bullom, Vai, Krim, Fulani and Malinke in the north and east; and the Sherbro in the southwest. The Krio people, also known as Creoles, reside mainly in and around Freetown. Lebanese and Indian communities also live in urban centres throughout the country.

The official language of Sierra Leone is English. There are also three indigenous languages that are spoken and adopted throughout the country. These are Mende (principal vernacular in the south), Temne (principal vernacular in the North), and Krio (English-based Creole spoken by 10% of the population but understood by 95%).

Cultural traditions

The communities of Sierra Leone are known for their unique styles of dance, song and costume often accompanied by the kelei (slit-log drum), sangbei (single-skin drum), segbure (rattle) and balaphones (wooden xylophones). Certain closed societies, such as the Wunde, the Sande (Bundu) and the Gola, have characteristic ceremonial dances. The carving and wearing of wooden masks in human and animal figures are also traditional features of the dances in communities who reside in the southern regions.

Colonisation to Independence

Sierra Leone was one of the first African countries to attract European colonial interest in the fifteenth century, beginning with the arrival of Portuguese explorer Pedro de Sintra in 1462. Sintra mapped the hills and harbour around what is now present-day Freetown, naming them “Serra da Leoa” or “Serra Leoa”. Meaning “Lioness Mountains”, this was the origin of Sierra Leone’s name.

In 1495, Portuguese traders began to settle in present-day Freetown and were welcomed by African chief rulers for the commercial opportunities they provided. The Portuguese established a fortified trading post on the coast that swiftly developed into a transit port for the slave trade. The Dutch, British and French also established trading stations nearby shortly after to primarily deal and ship enslaved west Africans, transforming the coast of Sierra Leone into a significant location of the transatlantic slave trade from the fifteenth to the eighteenth centuries.

In the latter part of the eighteenth century, Sierra Leone began to transform into a “Province of Freedom” for formerly enslaved Africans. The catalyst for this change began with Britain’s defeat in the American Revolutionary War in 1781. Thousands of Black Loyalists, former enslaved individuals who had supported the British war effort, were settled in different locations in Britain’s empire including London, the West Indies and Nova Scotia in Canada. Many had hoped for freedom, integration and support after they had fought for Britain, but instead they suffered severe poverty through a lack of employment and educational opportunities and were subjected to racial discrimination and violence. In 1787, the Committee for the Relief of the Black Poor, founded in London the year before, established a colony in Sierra Leone to provide a permanent home for the city’s impoverished Black population. Known as the “Province of Freedom”, the settlement initially welcomed around 400 Black men and women from Britain. Five years later, nearly 1,200 individuals arrived from Nova Scotia and in 1800, 500 formerly enslaved soldiers and their families arrived from Jamaica as a consequence of the Maroon Wars. The settlements of the Committee for the Relief of the Black Poor, the Nova Scotians and the Maroon community established the foundations of what became known as Freetown.

After the British Parliament outlawed the transatlantic slave trade in 1807, the British government took over the Freetown settlement and made it a crown colony on 1 January 1808. The Royal Navy used Freetown as a naval base against the slave trade and as a centre to which formerly enslaved Africans who had been liberated from illegal slave ships were relocated. Many chose to remain in Sierra Leone, helping to build Freetown’s heterogeneous population that developed into its own ethnic group, the Krio, with a unique language and cultural traditions.

The socio-political landscape of Freetown and wider Sierra Leone however changed dramatically under British colonial rule. The British government promised the settlers in Freetown self-governance, economic and educational opportunities and racial equality, however this failed to materialise. In 1896, a British protectorate was declared over Sierra Leone. To pay for the administration of the protectorate, a hut tax was imposed. The indigenous ruling chiefs, who had not been consulted about the tax, objected and a revolt headed by Bai Bureh occurred in 1898. This was brutally suppressed by the British authorities and became the final large-scale armed uprising against British colonisation in Sierra Leone. With the protectorate officially established, British district commissioners took ruling powers away from the local chiefs and many Krios who had held senior official posts throughout the nineteenth century were removed from office. Sierra Leone and Freetown became completely governed by British administrators.

The economic and environmental landscape of Sierra Leone were also transformed for British advantage. Imports and exports skyrocketed. Between 1900 and 1918 the annual value of exports rose from £360,000 to £1.5 million, and by the 1930s, tax on agricultural exports accounted for 75% of the colonial administration’s revenues. Land and coastal areas were also irrevocably altered and damaged due to intensive mining for the extraction of economically valuable platinum, gold, chrome, iron ore and diamonds. Between 1931 and 1961 minerals went from 5% of Sierra Leone’s domestic exports to 87%.

Due to oppressive British rule and control over Sierra Leone’s social, political and economic structures, anti-colonial sentiment grew dramatically amongst the indigenous and settlement communities in the country throughout the late eighteenth and early nineteenth centuries. This led to the British government constituting democratic institutions throughout the 1950s that led to Sierra Leone achieving independence within the Commonwealth on 27 April 1961.
