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.

Outgoing president: Ellen Johnson Sirleaf
Ellen Johnson Sirleaf became Africa's first female president in 2005, two years after the end of a brutal 14-year conflict.
She was re-elected in November 2011 in a poll marred by a low turn-out and a boycott by her main rival, Winston Tubman.
She is due to step down following elections in October 2017.
She was awarded the Nobel peace prize in 2011 for what the prize committee said were her efforts to secure peace, promote economic and social development and strengthen the position of women.
Born in 1938, she is a widowed mother-of-four.
- The first round of the presidential election was held on 10 October 2017 and the second round was scheduled for 7 November. Former football star George Weah is to compete against Vice President Joseph Boakai.
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.
