Nazi Germany is the common English name for the period in German history from 1933 to 1945 when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party (NSDAP).

The official name of the state was Deutsches Reich from 1933 to 1943 and Großdeutsches Reich (Greater German Reich) from 1943 to 1945. The period is also known under the names the Third Reich (German: Drittes Reich) and the National Socialist Period (German: Zeit des Nationalsozialismus, abbreviated as NS-Zeit). The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945.

Racism was a central feature of the regime. The Germanic peoples (the Nordic race) were considered by the Nazis to be the purest branch of the Aryan race and were therefore viewed as the master race. Education focused on racial biology, population policy, and fitness for military service. The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum for the Germanic people. Nazi Germany's racial policy was based on their belief in the existence of a superior master race. The Nazis postulated the existence of a racial conflict between the Aryan master race and inferior races, particularly Jews, who were viewed as a mixed-race that had infiltrated society and were responsible for the exploitation and repression of the Aryan race.

Germany has a long tradition of bureaucracy, everything has to be accurately documented, stamped, filed and organized. The National Socialists perfected this system and created a complex identity documents system that has no match anywhere else in the world. Every organization, sports club, hobby group or whatever else it might have been where a number of people with the same interests met created an identity document, some with, some without a photo. In one way or another, they were all somehow affiliated to the Nazi party, attended meetings were recorded in these documents, paid fees were documented, work or military history/career, virtually everything. Often several ID documents were linked together and the entries in each document had to match with the other ID documents.

Civilian Identity Card (Kennkarte)
   
Passport (Reisepass)

There are four types of standard passports issued during Deutsches Reich.
The internal pages of these passports are all identical and all were issued by the Polizeipräsident (Head of the Police).
 
There also was a version for Jews, the document was nearly identical but had a letter "J" stamped into the name section of the passport.

Service Passport (Dienstpass)

Employment Record Book (Arbeitsbuchs)

The workbook was a result of the Labor Law of February 1935 that required labour registration and the use of the appropriate document. The purpose of the Arbeitsbuch was to document the work history of each German citizen. During the twelve years of the Third Reich, the Arbeitsbuch came in three editions. The main difference was the variations of the cover. The first style (far left) came with a Weimar eagle and small swastikas on all four corners and the words Deutsches Reich andArbeitsbuch in the old German Fraktur lettering. On the cover of the second style, the Nazi eagle replaced the Weimar eagle and the swastikas in the corners were discontinued. The third style had a slightly changed Nazi eagle but the Fraktur lettering was replaced by the simpler Altschrift. The Arbeitsbuch had, depending on which edition, between 32 and 38 pages. This document was for German citizens only, foreigners who worked in the Reich had to carry a similar book which was printed on a different colour paper and which contained a photo of the owner while no photo was required in the domestic document.

It contained information on every job its bearer had during his working life (with dates, employer and type of employment given, but excluding military service which was documented in the Wehrpassand certain other exceptions like employment as a civil service official) and was handed over by the employee to the employer when taking up work there; the employer made the relevant entries into the document, kept it for the duration of the holder's employment and handed it back to him or her when he/she left the employer's service. 

Firms were prohibited by law to hire anybody without a valid workbook; the purpose of this document - whose data were also kept with the labour office's records - was to aid in the disposition of the available workforce and to help in registering so-called "Arbeitsscheue" (= persons who were deemed "unwilling to work" and considered anti-social by the Nazis) 

The cover of the Arbeitsbuch for German nationals was of similar design, but brown and marked "Deutsches Reich" above and "Arbeitsbuch" below the national insignia, which on early examples was still of the style with drooping wings and without the Swastika.

Two major varieties: German and "Workbook for foreigners".
