Ivory Coast–Liberia border in the context of Maryland County

Liberia, officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest. It has a population of around 5.5 million and covers an area of 43,000 square miles (111,369 km). The official language is English. Over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. The capital and largest city is Monrovia.

Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed that black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born African Americans, along with 3,198 Afro-Caribbeans, relocated to Liberia. Gradually developing an Americo-Liberian identity, the settlers carried their culture and tradition with them while colonizing the indigenous population. Led by the Americo-Liberians, Liberia declared independence on July 26, 1847, which the U.S. did not recognize until February 5, 1862.

Ivory Coast, also known as Côte d'Ivoire and officially the Republic of Côte d'Ivoire, is a country on the southern coast of West Africa. Its capital city of Yamoussoukro is located in the centre of the country, while its largest city and economic centre is the port city of Abidjan. It borders Guinea to the northwest, Liberia to the west, Mali to the northwest, Burkina Faso to the northeast, Ghana to the east, and the Atlantic Ocean's Gulf of Guinea to the south. With 31.5 million inhabitants in 2024, Ivory Coast is the third-most populous country in West Africa. Its official language is French, and indigenous languages are also widely used, including Bété, Baoulé, Dyula, Dan, Anyin, and Cebaara Senufo. In total, there are around 78 languages spoken in Ivory Coast. The country has a religiously diverse population, including numerous followers of Islam, Christianity, and traditional faiths often entailing animism.

Before its colonisation, Ivory Coast was home to several states, including Gyaaman, the Kong Empire, and Baoulé. The area became a protectorate of France in 1843 and was consolidated as a French colony in 1893 amid the Scramble for Africa. It achieved independence in 1960, led by Félix Houphouët-Boigny, who ruled the country until 1993. Relatively stable by regional standards, Ivory Coast established close political-economic ties with its West African neighbours while maintaining close relations with the West, especially France. Its stability was diminished by a coup d'état in 1999 and two civil wars—first between 2002 and 2007 and again during 2010–2011. It adopted a new constitution in 2016.
