Liberia

The territory of present-day Liberia has been inhabited for many centuries by peoples speaking languages of the Mande, Kru, and Mel branches of the Niger-Congo family. Successive migrations, particularly between the twelfth and sixteenth centuries, brought groups such as the Vai, Gola, Kpelle, Loma, Bassa, Kru, Grebo, and Mandingo into the forested coast and interior. These societies organised themselves into chiefdoms and confederations, practised shifting agriculture and trade in salt, kola nuts, gold, and forest products, and were drawn into wider regional networks linked to the Mali and later Songhai empires. The Vai of the coast developed an indigenous syllabic script in the 1830s, one of the few writing systems devised independently in West Africa. From the late fifteenth century, Portuguese, Dutch, French, and British mariners frequented the coast, which European cartographers came to call the Grain Coast after the malagueta pepper, or "grains of paradise," exported from its shores.

Liberia's modern state originated in the colonisation movement of the early nineteenth century. The American Colonization Society, founded in 1816, began settling free African Americans, freeborn people of colour, and later recaptured Africans from intercepted slave ships at Cape Mesurado in 1822. The settlement, named Monrovia for United States President James Monroe, expanded into a commonwealth and on 26 July 1847 declared independence as the Republic of Liberia under Joseph Jenkins Roberts, becoming Africa's first modern republic. The constitution borrowed heavily from that of the United States, and political life was dominated for more than a century by the Americo-Liberian minority and the True Whig Party, which held continuous power from 1878. During the Scramble for Africa, Liberia preserved its formal sovereignty but ceded substantial territory to British Sierra Leone and French West Africa under treaties concluded between 1885 and 1911.

The twentieth century saw Liberia integrated into the global economy through the 1926 Firestone rubber concession and, during the Second World War, through American military bases and Lend-Lease infrastructure. Liberia was a founding member of the United Nations in 1945 and of the Organization of African Unity in 1963. The long presidency of William V. S. Tubman (1944 to 1971) introduced limited franchise reforms and an open-door investment policy, while his successor William R. Tolbert faced rising social tensions that culminated in the 1980 coup d'état led by Master Sergeant Samuel Doe, ending Americo-Liberian political dominance.

Doe's authoritarian rule collapsed into the First Liberian Civil War (1989 to 1997), triggered by Charles Taylor's incursion from Côte d'Ivoire and marked by ECOWAS military intervention. Taylor was elected president in 1997, but renewed insurgency produced the Second Civil War (1999 to 2003), which ended with his exile and the deployment of a United Nations mission. A transitional government oversaw the 2005 elections, in which Ellen Johnson Sirleaf became Africa's first elected woman head of state. She served two terms, navigated the 2014 to 2016 Ebola epidemic, and in 2018 transferred power to former footballer George Weah, the country's first peaceful constitutional handover in generations. In the October 2023 election, Joseph Boakai of the Unity Party defeated Weah and took office in January 2024.

Liberia is today a unitary presidential republic, with executive authority vested in the directly elected president and a bicameral legislature comprising the Senate and the House of Representatives.
