The Germans (Deutsche) are a Germanic ethnic group native to Central Europe. The English term Germans has referred to the German-speaking population of the Holy Roman Empire since the Late Middle Ages. Legally, Germans are citizens of the Federal Republic of Germany.

Of approximately 100 million native speakers of German in the world, about 66–75 million consider themselves Germans. There are an additional 80 million people of German ancestry mainly in the United States, Brazil, Canada, Argentina, France, Russia, Chile, Poland, Australia and Romania who most likely are not native speakers of German. Thus, the total number of Germans worldwide lies between 66 and 160 million, depending on the criteria applied (native speakers, single-ancestry ethnic Germans, partial German ancestry, etc.).

Today, peoples from countries with a German-speaking majority or significant German-speaking population groups other than Germany, such as Austria, Switzerland, Liechtenstein and Luxembourg, have developed their own national identity and usually do not refer to themselves as "Germans" in a modern context.

Adolf Hitler (German: [ˈadɔlf ˈhɪtlɐ] ( listen); 20 April 1889 – 30 April 1945) was an Austrian-born German politician and the leader of the National Socialist German Workers Party (German: Nationalsozialistische Deutsche Arbeiterpartei (NSDAP), commonly referred to as the Nazi Party). He was chancellor of Germany from 1933 to 1945 and dictator of Nazi Germany (as Führer und Reichskanzler) from 1934 to 1945. Hitler is commonly associated with the rise of fascism in Europe, World War II, and the Holocaust.

A decorated veteran of World War I, Hitler joined the German Workers' Party, precursor of the Nazi Party, in 1919, and became leader of the NSDAP in 1921. In 1923, he attempted a coup d'état, known as the Beer Hall Putsch, in Munich. The failed coup resulted in Hitler's imprisonment, during which time he wrote his memoir, Mein Kampf (My Struggle). After his release in 1924, Hitler gained popular support by attacking the Treaty of Versailles and promoting Pan-Germanism, antisemitism, and anticommunism with charismatic oratory and Nazi propaganda. After his appointment as chancellor in 1933, he transformed the Weimar Republic into the Third Reich, a single-party dictatorship based on the totalitarian and autocratic ideology of Nazism. His aim was to establish a New Order of absolute Nazi German hegemony in continental Europe.
