Cameroon country profile
Cameroon is often known as "Africa in miniature" because of its geographical and cultural diversity.
The Central African country has one of the highest literacy rates on the continent, but its economic progress has been hampered by corruption and decades of authoritarian rule.
Created in 1961 by the unification of a British and a French colony, the modern state of Cameroon has also struggled to find peace and unity.
Internally, there are tensions over the two mainly English-speaking south-western provinces. A secessionist movement emerged in the 1990s, and turned into an insurgency in 2016.
The mainly-Muslim far north has been drawn into the regional Islamist insurgency of the Boko Haram group.
President: Paul Biya
In power since 1982, Paul Biya is one of Africa's most entrenched leaders.
Parliament passed a controversial amendment in 2008 allowing him to run for office again, and he won new seven-year terms in 2011 and 2018 in votes marred by irregularities.
His party, the Cameroonian People's Democratic Movement (RDPC), has won landslide majorities in every parliamentary election since 1992.
Before becoming president, Mr Biya spent his entire political career in the service of President Ahmadou Ahidjo, becoming prime minister in 1975.
In 1983 he accused Mr Ahidjo of organising a coup against him, forcing the former president to flee the country.
State-run CRTV operates alongside dozens of private radio and TV stations.
Journalists reporting on sensitive subjects risk legal action, says Freedom House.
Amid protests in English-speaking regions, internet access in these areas has been disrupted.
Some key dates in Cameroon's history:
