since the Nazi seizure of power in 1933. He said that between 1933 and October 1941, 537,000 German, Austrian, and Czech Jews had emigrated. This information was taken from a briefing paper prepared for him the previous week by Eichmann. Heydrich reported that there were approximately eleven million Jews in the whole of Europe, of whom half were in countries not under German control. He explained that since further Jewish emigration had been prohibited by Himmler, a new solution would take its place: "evacuating" Jews to the east. This would be a temporary solution, a step towards the "final solution of the Jewish question". German historian Peter Longerich notes that vague orders couched in terminology that had a specific meaning for members of the regime were common, especially when people were being ordered to carry out criminal activities. Leaders were given briefings about the need to be "severe" and "firm"; all Jews were to be viewed as potential enemies that had to be dealt with ruthlessly. The wording of the Wannsee Protocol—the distributed minutes of the meeting—made it clear to participants that evacuation east was a euphemism for death. Heydrich went on to say that in the course of the "practical execution of the final solution", Europe would be "combed through from west to east", but that Germany, Austria, and the Protectorate of Bohemia and Moravia would have priority, "due to the housing problem and additional social and political necessities". This was a reference to increasing pressure from the Gauleiters (regional Nazi Party leaders) in Germany for the Jews to be removed from their areas to allow accommodation for Germans made homeless by Allied bombing, as well as to make space for laborers being imported from occupied countries. The "evacuated" Jews, he said, would first be sent to "transit ghettos" in the General Government, from which they would be transported eastward. Heydrich said that to avoid legal and political difficulties, it was important to define who was a Jew for the purposes of "evacuation". He outlined categories of people who would not be killed. Jews over 65 years old, and Jewish World War I veterans who had been severely wounded or who had won the Iron Cross, might be sent to Theresienstadt concentration camp instead of being killed. "With this expedient solution", he said, "in one fell swoop, many interventions will be prevented." The situation of people who were half
