Berlin is Germany's capital and co-extensive with the Land of Berlin, one of the 16 federal states that make up the Federal Republic of Germany. With a population of 3.8 million (2019) (and a million more in "suburbs" like Potsdam across the state line in Brandenburg), Berlin is Germany's biggest city. The focus on and dominance of Berlin as a capital is and has historically been far weaker than that of London, Paris or Madrid, not least because of the federal nature of Germany and the havoc war and partition wreaked on the city. - Wikivoyage - Image by @purzlbaum
