One of the sixteen states of Germany and its capital, Berlin is the largest city of Germany. It covers and area of around three hundred and forty four square miles and is home to over three million people inside the limits of the city. The city is the second most populated city of the European Union and the urban area is the ninth most populated area of the European Union. Berlin is located in the north east of Germany and it also forms the center of the metropolitan area called Berlin-Brandenburg. This area is home to around five million people who have come here from more than one hundred and eighty different nations.
Berlin has had the status of being the capital of the Kingdom of Prussia, the Weimar Republic, the Third Reich, and the German Empire. When the Second World War ended, the city was divided into two separate parts; East Berlin and West Berlin. When Germany was reunified in the year 1990, Berlin became the capital of the whole of Germany once more. Until then the capital of East Germany was East Berlin and West Berlin was turned into a Western enclave holed in by the Berlin Wall. This situation continued from the year 1961 to 1989.
Another important aspect of Berlin is that it is the hub of science, politics, media, and culture in Europe, as well as being the continental center for rail and air transport. The major portion of the economy of Berlin is dependable on the provision of services, which include environmental services, creative industries, convention venues, and media corporations. The city is also visited by a large number of tourists every year and is a very popular place in the European Union. There are other major industries here as well such as health care, biotechnology, vehicle manufacturing, and traffic engineering.
