Bolivia country profile
A country of extremes, landlocked Bolivia is the highest and most isolated country in South America.
It has the largest proportion of indigenous people, who make up around two-thirds of the population.
The country has the second-largest reserves of natural gas in South America, but there have been long-running tensions over the exploitation and export of the resource. Indigenous groups say the country should not relinquish control of the reserves, which they see as Bolivia's sole remaining natural resource.
Bolivia is also one of the world's largest producers of coca, the raw material for cocaine. A crop-eradication programme, though easing the flow of conditional US aid, has incensed many of Bolivia's poorest farmers for whom coca is often the only source of income.

President: Evo Morales
First elected in December 2005, Evo Morales, from the Aymara indigenous group, is first president to come from the country's indigenous majority.
As a leader of a coca-growers union, he was also the first president to emerge from the social movements whose protests forced Bolivia's two previous presidents from office.
Having come to power with a radical programme aimed at addressing the extreme social divisions and inequalities of Bolivia, he achieved in a few short years real social gains for the majority of Bolivians.
Mr Morales' political ideology combines standard left-wing ideas with an emphasis on traditional indigenous Andean values and concepts of social organisation.
By the middle of 2006, he had renationalised Bolivia's oil and gas industries.
With the gas money, Mr Morales's administration invested heavily in public works projects and social programmes to fight poverty which reduced by 25% during his government. Extreme poverty dropped by 43%.
In February 2016, Mr Morales lost a referendum that would have allowed him to run for president for a fourth term.
Bolivia's media landscape is dominated by private newspapers and broadcasters
With hundreds of stations, radio is important, especially in rural areas.
The authorities use legal, political and economic means to pressure independent media, says Freedom House.
Some key dates in Bolivia's history:
