In 2008, the President of the Republic of Cameroon, President Paul Biya signed decrees abolishing "Provinces" and replacing them with "Regions". Hence, all of the country's ten provinces are now known as Regions. The province is divided into four departments (departements): These are in turn broken down into subdivisions. Presidentially appointed senior divisional officers (prefets) and subdivisional officers (sous-prefets) govern each respectively. Traditional leaders, usually referred to as chiefs in English, often preside over particular ethnic groups or villages; nevertheless, many of these wield very little power today.
