During war, civilians have been concentrated in camps to prevent them from engaging in guerrilla warfare or providing aid to enemy forces or simply as a means of terrorizing the populace into submission. During the South African War (1899–1902) the British confined noncombatants of the republics of Transvaal and Cape Colony in concentration camps. Another instance of interning noncombatant civilians occurred shortly after the outbreak of hostilities between Japan and the United States (December 7, 1941), when more than 100,000 Japanese and Japanese-Americans on the West Coast were taken into custody and placed in camps in the interior.
If, up to now, we had interpreted our fate only as a privation of liberty, our experience changed rapidly. We had to jump down from the truck without the aid of a chair, and the request for a helping hand was denied with abuse. One of our comrades, an older man lacking the agility of youth, fell in this enforced jump and hurt the back of his head so badly that his skin had to be sewed with several stitches. Hardly were we standing on the ground when a pack of young men in S.S. uniforms, with yells and abuse, chased us to the other end of the large, inner, so-called inspection ground, which is surrounded by the barracks of the prisoners. Those who couldn't run fast enough were kicked.
Between 1939 and 1945, the Nazi Party led regime, assisted by collaborationist governments and recruits from occupied countries, was responsible for the deaths of at least eleven million people,[94][95] including 5.5 to 6 million Jews (representing two-thirds of the Jewish population of Europe),[11][96][97] and between 200,000 and 1,500,000 Romani people.[98][99] The estimated total number includes the killing of nearly two million non-Jewish Poles,[100] over three million Soviet prisoners of war,[101] communists, and other political opponents, homosexuals, the physically and mentally disabled.[102][103]
Groups like Patriot Front, a spin-off of Vanguard America that was founded by Thomas Rousseau when he was 19 years old, and Identity Europa, aggressively try to recruit teens on high school and college campuses, Hankes said. He noted that the Internet and social media outlets have proved invaluable to recruitment efforts by these groups and hastened the spread of their racist ideologies.

On 26 June 1933, Himmler appointed Theodor Eicke commandant of Dachau, who in 1934 was also appointed the first Inspector of Concentration Camps (CCI). In addition, the remaining SA-run camps were taken over by the SS.[14][15][16] Dachau served as both a prototype and a model for the other Nazi concentration camps. Almost every community in Germany had members who were taken there. The newspapers continuously reported on "the removal of the enemies of the Reich to concentration camps" making the general population more aware of their presence. There were jingles warning as early as 1935: "Dear God, make me dumb, that I may not come to Dachau."[17]
