A department (French: département, Spanish: departamento) is an administrative or political division in several countries.An additional 10 countries use departments as second-level divisions, eight in Africa, and one each in the Americas and Europe.(The term "department", in other contexts, means an administrative sub-division of a larger organization.)The division of France into departments was a project particularly identified with the French revolutionary leader the Abbé Sieyès, although it had already been frequently discussed and written about by many politicians and thinkers.Today, departments may exist either with or without a representative assembly and executive head depending upon the countries' constitutional and administrative structure.
