In 1920, Hitler announced a 25-point plan for his Nazy Party. Points included:
4. Only a member of the Aryan race can be a citizen. A member of the race can only be one who is of German blood, without consideration of creed. Consequently, no Jew can be a member of the race.
5. Whoever has no citizenship is to be able to live in Germany only as a guest, and must be under the authority of legislation for foreigners.
6. The right to determine matters concerning administration and law belongs only to the citizen. Therefore, we demand that every public office, of any sort whatsoever, whether in the Reich, the county or municipality, be filled only by citizens […]
7. We demand that the state be charged first with providing the opportunity for a livelihood and way of life for the citizens. If it is impossible to sustain the total population of the state, then the members of foreign nations (non-citizens) are to be expelled from the Reich.
