Cameroon is a West-Central African nation often called "Africa in miniature" for its diverse geology and culture, featuring a variety of landscapes from rainforests to deserts and a rich tapestry of over 200 ethnic groups and languages. Its official languages are French and English, with its capital in Yaoundé and its largest city being Douala. The country, a unitary republic, gained independence from French and British trusteeships in the 1960s and is led by President Paul Biya. Economically, Cameroon's primary sectors include agriculture, industry, and services, with oil playing an important role, though poverty remains a significant challenge.
