Germany, being a Federal Republic, is divided into 16 Länder (Bundesländer). Länder have more power than provinces or administrative districts, but less power than for example US states. (The category is named States as this term is more widely understood than the correct term Länder.)
Overview article on the 16 German states, their constitutional role and their subdivisions, with maps.
