Franz Ziereis (also known as Franz Xaver Ziereis) was born on August 13, 1905, within the territory of the German Empire. The German Empire was a constitutional monarchy with a federal structure that had been established in 1871 and would dissolve in 1918. He subsequently became a citizen of the Weimar Republic (1918/1919–1933), which replaced the empire, and later of Nazi Germany (1933–1945), the period during which the Nazi Party controlled the country under Adolf Hitler's authoritarian rule. His work period began in 1924.

### SS Membership and Military Career
Ziereis joined the Schutzstaffel (SS), a Nazi paramilitary organization founded on April 4, 1925. The SS operated with the Waffen-SS as its military branch and was the organization primarily responsible for carrying out the mass murder of European Jews during the Holocaust. His occupation is classified as an officer role within this structure.

The German Empire under which he was born was a constitutional monarchy with a federal structure, capital in Berlin, and approximately 45 million residents at its peak. It was replaced by the Weimar Republic following the empire's dissolution in 1918. Nazi Germany then replaced the Weimar Republic in 1933, establishing an authoritarian state under the Nazi Party that pursued policies of racial discrimination, persecution of Jews, and military expansion. Nazi Germany was a member of the Axis Powers during World War II, had a population of approximately 79,730,000 in 1939, and used the Reichsmark as its currency. The regime was responsible for initiating World War II with the invasion of Poland in 1939 and was ultimately defeated in 1945.
