Germany is a country located in central Europe.
Germany was one of the major nations that mobilized during World War I, orchestrated by Ares. It was the dominant force in the Central Powers which fought, and lost to the Allied Powers, due in part to the latter side having the aid of superheroine Wonder Woman.
21 years later, following a revolution, Germany would participate in World War II, this time as a dominant force in the Axis Powers, but would ultimately lose to the Allied Powers again.
Following World War II, Germany was first occupied, and then later split into two countries - East and West Germany. Alexander Luthor Sr. was born and raised in East Germany before moving to the United States, and founding his own petrochemical and heavy machinery company called LexCorp Industries.
