Cameroon country profile

Cameroon is often known as "Africa in miniature" because of its geographical and cultural diversity.

The country has one of the highest literacy rates in Africa 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.

Since 2017, Cameroon's mainly English-speaking northwest and southwest regions have seen a guerrilla war between insurgents and government forces for the independence of the region as the Federal Republic of Ambazonia.

Hundreds of thousands have been internally displaced by the fighting. The conflict has also indirectly led to an upsurge in attacks by Boko Haram - part of the regional Islamist insurgency - as the army largely withdrew from the mainly-Muslim north to fight the anglophone separatists.

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.

Although Cameroon has one of the most diverse media landscapes in Africa, it is one of the continent's most dangerous countries for journalists, says Reporters without Borders (RSF).

Many media outlets practice self-censorship, as reporters can face harassment and threats if their reporting endangers government interests.
