Otto von Bismarck, the "Iron Chancellor", founded the German Empire in 1871 from many independent states, dominated by the Kingdom of Prussia. After four years of bitter fighting, Germany suffered a devastating defeat in World War I and the humiliating conditions of the peace settlement contributed to the rise to power of Adolf Hitler and the Nazis in 1933.
Hitler unleashed the Holocaust and plunged Europe and the world into its bloodiest-ever conflict that resulted in the death of tens of millions of people and the division of Germany and Berlin into four zones, shared by the victorious powers - Britain, France, the Soviet Union and the United States.
Divided Germany became the key Cold War battleground between nuclear superpowers Russia and the United States, whose tanks faced each other across the Berlin Wall, which was finally and jubilantly torn down by people power in 1989. Germany was reunified in 1990.
Germany has two houses of parliament, the Bundestag (lower house) and Bundesrat (upper house, representing the 16 federal states).
