Nazi Germany, or the Third Reich, is the common name for the country of Germany while governed by Adolf Hitler and his National Socialist German Workers' Party (NSDAP) from 1933 to 1945. Third Reich (German: Drittes Reich) denotes the Nazi state as a historical successor to the medieval Holy Roman Empire (962–1806) and to the modern German Empire (1871–1918). Nazi Germany had two official names, the Deutsches Reich (German Reich), from 1933 to 1943, when it became Großdeutsches Reich (Greater German Reich).
On 30 January 1933, Adolf Hitler was appointed Chancellor of Germany. Although he initially headed a coalition government, he quickly eliminated his government partners. At this time the German national borders still were those established in the peace Treaty of Versailles (1919), between Germany and the Allied Powers (United Kingdom, France, the United States, Italy, Japan et alii.) at the end of the First World War (1914–18); to the north, Germany was bounded by the North Sea, Denmark, and the Baltic Sea; to the east, it was divided into two and bordered Lithuania, the Free City of Danzig, Poland, and Czechoslovakia; to the south, it bordered Austria and Switzerland, and to the west, it touched France, Luxembourg, Belgium, the Netherlands, the Rhineland, and the Saarland. These borders changed after Germany regained control of the Rhineland, Saarland and the Memelland and annexed Austria, the Sudetenland and Bohemia and Moravia. Germany expanded into Greater Germany during the Second World War, which began in 1939 after Germany invaded Poland, triggering the United Kingdom and France to declare war on Germany.
