A typical concentration camp consisted of barracks that were secured from escape by barbed wire, watchtowers and guards. The inmates usually lived in overcrowded barracks and slept in bunk ”beds”. In the forced labour camps, for instance, the inmates usually worked 12 hours a day with hard physical work, clothed in rags, eating too little and always living under the risk of corporal punishment.

The food was probably sufficient as far as quantity goes, although our younger companions, who had to work very hard, could not satisfy their appetites. Besides the so-called Komissbrot (a dark bread baked for use in the army), which was difficult to digest for the city dweller not accustomed to hard physical labor, we usually had thick soups of leguminous plants or potatoes, with lumps of whale meat which, as far as I could find out, came in cans and tasted something like pork. However, it had nothing of the oily taste that might have been expected. Occasionally we had sweet milk soups with tapioca for breakfast, and for noon evening meal we had sandwiches with usage, cheese, margarine, and jam. It is an open question whether the decided loss in weight of many prisoners was due to the unusual food or to the mental depression. Food so poor in vitamins, however, must cause harm if taken for a long space of time.
Kamil Bedkowski, 33, worked as an art conservator in Britain for eight years, even restoring ceiling frescoes at Windsor Castle. Now he is on the team shoring up the crumbling brick barracks of Birkenau where thousands slept at a time, crammed into decaying three-level wooden bunks. “This is the most challenging project I’ve ever worked on,” he said.
Nine out of 10 victims in Auschwitz-Birkenau were Jews. The remaining victims were mainly Poles, gypsies, and Soviet POW’s. Majdanek began its gassings in October 1942. The camp functioned in the same way as Auschwitz-Birkenau, and also included a concentration- and work camp. In the autumn of 1943 the camp was closed after claiming between 60,000 and 80,000 Jewish victims.
Other Nazis—especially those at the time associated with the party's more radical wing such as Gregor Strasser, Joseph Goebbels and Heinrich Himmler—rejected Italian Fascism, accusing it of being too conservative or capitalist.[126] Alfred Rosenberg condemned Italian Fascism for being racially confused and having influences from philosemitism.[127] Strasser criticised the policy of Führerprinzip as being created by Mussolini and considered its presence in Nazism as a foreign imported idea.[128] Throughout the relationship between Nazi Germany and Fascist Italy, a number of lower-ranking Nazis scornfully viewed fascism as a conservative movement that lacked a full revolutionary potential.[128]
In January 1934, Germany signed a non-aggression pact with Poland.[73] In March 1939, Hitler demanded the return of the Free City of Danzig and the Polish Corridor, a strip of land that separated East Prussia from the rest of Germany. The British announced they would come to the aid of Poland if it was attacked. Hitler, believing the British would not actually take action, ordered an invasion plan should be readied for September 1939.[74] On 23 May, Hitler described to his generals his overall plan of not only seizing the Polish Corridor but greatly expanding German territory eastward at the expense of Poland. He expected this time they would be met by force.[75]

On the night of 8 November, the Nazis used a patriotic rally in a Munich beer hall to launch an attempted putsch ("coup d'état"). This so-called Beer Hall Putsch attempt failed almost at once when the local Reichswehr commanders refused to support it. On the morning of 9 November, the Nazis staged a march of about 2,000 supporters through Munich in an attempt to rally support. Troops opened fire and 16 Nazis were killed. Hitler, Ludendorff and a number of others were arrested and were tried for treason in March 1924. Hitler and his associates were given very lenient prison sentences. While Hitler was in prison, he wrote his semi-autobiographical political manifesto Mein Kampf ("My Struggle").
The first camp in Germany, Dachau, was founded in March 1933.[13] The press announcement said that "the first concentration camp is to be opened in Dachau with an accommodation for 5,000 people. All Communists and – where necessary – Reichsbanner and Social Democratic functionaries who endanger state security are to be concentrated there, as in the long run it is not possible to keep individual functionaries in the state prisons without overburdening these prisons."[13] Dachau was the first regular concentration camp established by the German coalition government of National Socialist Workers' Party (Nazi Party) and the Nationalist People's Party (dissolved on 6 July 1933). Heinrich Himmler, then Chief of Police of Munich, officially described the camp as "the first concentration camp for political prisoners."[13]
