In many instances, their imprisonment was a result of the emergency decree that Adolf Hitler proposed and President Paul Von Hindenberg approved on February 28, 1933. The Decree for the Protection of the People and the State (commonly called the Reichstag Fire Decree) suspended the civil rights of German civilians and prohibited the press from publishing anti-government materials.
The fire signaled the demise of German democracy. On the next day, the government, under the pretense of controlling the Communists, abolished individual rights and protections: freedom of the press, assembly, and expression were nullified, as well as the right to privacy. When the elections were held on March 5, the Nazis received nearly 44 percent of the vote, and with 8 percent offered by the Conservatives, won a majority in the government.
In 1935 the Wehrmacht began to build a large military complex close to the village of Belsen, a part of the town of Bergen, in what was then the Province of Hanover. This became the largest military training area in Germany of the time and was used for armoured vehicle training. The barracks were finished in 1937. The camp has been in continuous operation since then and is today known as Bergen-Hohne Training Area. It is used by the NATO armed forces.
