Liberia country profile
Liberia is Africa's oldest republic, but it became known in the 1990s for its long-running, ruinous civil war and its role in a rebellion in neighbouring Sierra Leone.
Although founded by freed American and Caribbean slaves, Liberia is mostly inhabited by indigenous Africans, with the slaves' descendants comprising 5% of the population.
Around 250,000 people were killed in Liberia's civil war and many thousands more fled the fighting.
Big programmes are under way to address the shortage of electricity and running water. Corruption is rife and unemployment and illiteracy are endemic.

President: George Weah
Former football start George Weah secured a stunning run-off victory in December 2017 in the country's first democratic transfer of power in decades.
Idolised in Liberia as "Mister George", Mr Weah replaced Ellen Johnson Sirleaf, who became president in 2006.
His rival, Vice President Joseph Boakai, conceded defeat.
In his first public comments since his victory, Weah told journalists in Monrovia he aimed to "improve the lives" of Liberians.
Weah, 51 at the time of his election, starred in top-flight football at Paris Saint-Germain and AC Milan in the 1990s and briefly at Chelsea and Manchester City before entering politics in 2002.
Liberia's media scene includes private and state outlets. Radio is the main news source and there is a lively commercial sector.
There is real media freedom, says watchdog Reporters Without Borders.
