The Pepper Coast has been inhabited at least as far back as the 12th century, perhaps earlier. Mende-speaking people expanded westward from Sudan, forcing many smaller ethnic groups southward towards the Atlantic ocean. The Dei, Bassa, Kru, Gola and Kissi were some of the earliest recorded arrivals.[3] This influx was compounded by the decline of the Western Sudanic Mali Empire in 1375 and later in 1591 with the Songhai Empire.
Additionally, inland regions underwent desertification, and inhabitants were pressured to move to the wetter coast. These new inhabitants brought skills such as cotton spinning, cloth weaving, iron smelting, rice and sorghum cultivation, and social and political institutions from the Mali and Songhai Empires.[4] Shortly after the Manes conquered the region, the Vai people of the former Mali Empire immigrated into the Grand Cape Mount region. The ethnic Kru opposed the influx of Vai, forming an alliance with the Manes to stop further influx of Vai.
People along the coast built canoes and traded with other West Africans from Cap-Vert to the Gold Coast. Between 1461 and late 17th century, Portuguese, Dutch and British traders had contacts and trading posts in the region. The Portuguese named the area Costa da Pimenta, meaning Pepper Coast but later translated as Grain Coast, because of the abundance of grains of melegueta pepper. European traders would barter various commodities and goods with local people. When the Kru began trading with Europeans, they initially traded in commodities, but later they actively participated in the African slave trade.
In 1820, the American Colonization Society (ACS) began sending black volunteers to the Pepper Coast to establish a colony for freed American slaves.[5] The ACS, a private organization supported by prominent American politicians such as Henry Clay and James Monroe, believed repatriation was preferable to emancipation of slaves. Similar organizations established colonies in Mississippi-in-Africa and the Republic of Maryland, which were later annexed by Liberia. On July 26, 1847, the settlers issued a Declaration of Independence and promulgated a constitution, which created the independent Republic of Liberia.
The leadership of the new nation consisted largely of the Americo-Liberians. The 1865 Ports of Entry Act prohibited foreign commerce with the inland tribes. In 1877, the Americo-Liberian True Whig Party was the most powerful political power in the country. Competition for office was usually contained within the party, whose nomination virtually ensured election.
Pressure from the United Kingdom and France led to a loss of Liberia's claims to extensive territories, which were annexed by adjoining countries. Economic development was hindered by the decline of markets for Liberian goods in the late 19th century and by indebtedness on a series of international loans. In Liberia's early years, the Americo-Liberian settlers periodically encountered stiff and sometimes violent opposition from the earlier settlers and immigrants, who became citizens of the Republic in 1904.
In the mid-20th century, Liberia gradually began to modernize with American assistance. Both the Freeport of Monrovia and Roberts International Airport were built by U.S. personnel through the Lend-Lease program during World War II. President William Tubman encouraged foreign investment in the country, resulting in the second-highest rate of economic growth in the world during the 1950s.
Liberia also began to take a more active role in international affairs. It was a founding member of the United Nations in 1945 and became a vocal critic of the South African apartheid regime. Liberia also served as a proponent both of African independence from the European colonial powers and of Pan-Africanism, helping to found the Organization of African Unity.
On April 12, 1980, a military coup led by Master Sergeant Samuel Doe of the Krahn ethnic group overthrew and killed President William R. Tolbert, Jr.. Doe and the other plotters later executed a majority of Tolbert's cabinet and other Americo-Liberian government officials and True Whig Party members. The coup leaders formed the People's Redemption Council (PRC) to govern the country. A strategic Cold War ally, Doe received significant financial backing from the United States while critics condemned the PRC for corruption and political repression.
After the country adopted a new constitution in 1985, Doe was elected president in subsequent elections that were internationally condemned as fraudulent. On November 12, 1985, a failed counter-coup was launched by Thomas Quiwonkpa, whose soldiers briefly occupied the national radio station. Government repression intensified in response, as Doe's troops executed members of the Gio and Mano ethnic groups in Nimba County.
The National Patriotic Front of Liberia, a rebel group led by Charles Taylor, launched an insurrection in December 1989 against Doe's government with the backing of neighboring countries such as Burkina Faso and Côte d'Ivoire, triggering the First Liberian Civil War.[18] By September 1990, Doe's forces controlled only a small area just outside the capital, and Doe was captured and executed that month by rebel forces.
The rebels soon split into various factions fighting one another, and the Economic Community Monitoring Group under the Economic Community of West African States organized a military task force to intervene in the crisis.[19] From 1989 to 1996 one of Africa's bloodiest civil wars ensued, claiming the lives of more than 200,000 Liberians and displacing a million others into refugee camps in neighboring countries.[12] A peace deal between warring parties was reached in 1995 leading to Taylor's election as president in 1997.
Under Taylor's leadership, Liberia became internationally known as a pariah state due to his use of blood diamonds and illegal timber exports to fund the Revolutionary United Front in the Sierra Leone Civil War. The Second Liberian Civil War began in 1999 when Liberians United for Reconciliation and Democracy, a rebel group based in the northwest of the country, launched an armed insurrection against Taylor.[21] In March 2003, a second rebel group, Movement for Democracy in Liberia, began launching attacks against Taylor from the southeast. Peace talks between the factions began in Accra in June of that year, and Taylor was indicted by the Special Court for Sierra Leone for crimes against humanity that same month.
By July 2003, the rebels had launched an assault on Monrovia. Under heavy pressure from the international community and the domestic Women of Liberia Mass Action for Peace movement, Taylor resigned in August and went into exile in Nigeria, and a peace deal was signed later that month. The United Nations Mission in Liberia began arriving in September 2003 to provide security and monitor the peace accord, and an interim government took power the following October.
The subsequent 2005 elections were internationally regarded as the most free and fair in Liberian history.[28] Ellen Johnson Sirleaf, a Harvard-trained economist and former Minister of Finance, was elected as the first female president in Africa.[28] Upon her inauguration, Sirleaf requested the extradition of Taylor from Nigeria and immediately handed him over to the SCSL for trial in The Hague.[29][30] In 2006, the government established a Truth and Reconciliation Commission to address the causes and crimes of the civil war.
