Erich Johann Albert Raeder was a German admiral who played a major role in the naval history of World War II, and was convicted of war crimes after the war. Raeder attained the highest possible naval rank, that of grand admiral, in 1939, becoming the first person to hold that rank since Henning von Holtzendorff in 1918. Raeder led the Kriegsmarine for the first half of the war; he resigned in January 1943 and was replaced by Karl Dönitz. At the Nuremberg trials he was sentenced to life imprisonment but was released early owing to failing health in 1955.

Nazi Germany, officially known as the German Reich and later the Greater German Reich, is a term used to describe the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", referred to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which the Nazis referred to as the Thousand-Year Reich, ended in May 1945, after only 12 years, when the Allies defeated Germany and entered the capital, Berlin, ending World War II in Europe.
