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 5.5million and covers an area of . The official language is English, though 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. Liberia was the first African republic to gain independence and is Africa's oldest continuously independent country. Ethiopia was never colonized, but endured an Italian occupation from 1936 to 1941. Both Liberia and Ethiopia were spared from the European colonial Scramble for Africa. Early 20th century Liberia saw large investment in rubber production by Firestone Tire and Rubber Company. These investments led to large-scale changes in Liberia's economy, work force, and climate. During World War II, Liberia supported the U.S. war effort against Nazi Germany and in turn received considerable American investment in infrastructure, which aided the country's wealth and development. President William Tubman encouraged economic and political changes that heightened the country's prosperity and international profile; Liberia was a founding member of the League of Nations, United Nations, and the Organisation of African Unity. In 1980, political tensions from the rule of William Tolbert resulted in a military coup, marking the end of Americo-Liberian rule and the seizure of power by Liberia's first indigenous leader, Samuel Doe. Establishing a dictatorial regime, Doe was assassinated in 1990 in the context of the First Liberian Civil War which ran from 1989 until 1997 with the election of rebel leader Charles Taylor as president. In 1998, the Second Liberian Civil War erupted against his own dictatorship, and Taylor resigned by the end of the war in 2003. The two wars resulted in the deaths of 250,000 people (about 8% of the population) and the displacement of many more, with Liberia's economy shrinking by 90%. A peace agreement in 2003 led to democratic elections in 2005. The country has remained relatively stable since then. Mining in Liberia has been a significant economic driver since the 1960s, though it largely stopped during the Liberian civil wars. Since the end of the civil wars, mining activity increased with emphasis on industrial mining. Mining has also led to concerns about environmental degradation and environmental destruction such as deforestation, water pollution, and air pollution. Industrial miners' poor wages, working conditions, and living conditions have sparked protests from the beginning of the Liberian mining industry continuing to today.
