In January 1933, after a bitter ten-year political struggle, Adolf Hitler came to power in Germany. During his rise to power, Hitler had repeatedly blamed the Jews for Germany's defeat in World War I and subsequent economic hardships. Hitler also put forward racial theories asserting that Germans with fair skin, blond hair and blue eyes were the supreme form of human, or master race. The Jews, according to Hitler, were the racial opposite, and were actively engaged in an international conspiracy to keep this master race from assuming its rightful position as rulers of the world.

Because they refused to pledge allegiance to the Nazi party or serve in the military, Jehovah's Witnesses were sent to concentration camps, where they were identified by purple triangles and given the option of renouncing their faith and submitting to the state's authority.[447] The United States Holocaust Memorial Museum estimates that between 2,700 and 3,300 were sent to the camps, where 1,400 died;[411] in The Holocaust Encyclopedia (2001), Sybil Milton estimates that 10,000 were sent and 2,500 died.[412] According to German historian Detlef Garbe, "no other religious movement resisted the pressure to conform to National Socialism with comparable unanimity and steadfastness."[448]

According to the copyright laws in the European Union, as a general rule, rights of authors end seventy years after their death. Hence, the copyright of the diary expired on 1 January 2016. In the Netherlands, for the original publication of 1947 (containing parts of both versions of Anne Frank's writing), as well as a version published in 1986 (containing both versions completely), copyright initially would have expired not 50 years after the death of Anne Frank (1996), but 50 years after publication, as a result of a provision specific for posthumously published works (1997 and 2036, respectively).
One of the most atrocious eras in human history is without a doubt the Holocaust. About 11 million people, including approximately 6 million Jews, are estimated to have been slaughtered at the hands of Adolf Hitler and the Nazi Party. Jews were forced to live in ghettos and then rounded up to be sent to concentration and extermination camps, where they were herded into gas chambers and killed. At a number of concentration camps, Nazi doctors conducted gruesome and horrific medical experiments on prisoners against their will. This leads us to one of the most infamous Nazi doctors who ever lived, Dr. Josef Mengele.
Death: Dr. Miklos Nyiszli was Mengele's prisoner pathologist. The autopsies became the final experiment. Nyiszli performed autopsies on twins who had died from the experiments or who had been purposely killed just for after-death measurements and examination. Some of the twins had been stabbed with a needle that pierced their heart and then was injected with chloroform or phenol, which caused near immediate blood coagulation and death. Some of the organs, eyes, blood samples and tissues would be sent to Verschuer for further study.
Mengele was an attractive man. A perennial little smile showed the gap between his front teeth. Immaculately dressed in jodhpurs, he wore a cap bearing the SS insignia and carried the obligatory riding crop, constantly slapping it against his gleaming black boots. Whenever he spoke to me, he was very polite, giving the impression that he was interested in me. It was hard to believe that his little smile and courteous behavior were just a facade behind which he devised the most horrific murderous schemes.
Hitler intended to blame the Jews for the new world war he was soon to provoke. That war began in September 1939 as German troops stormed into Poland, a country that was home to over three million Jews. After Poland's quick defeat, Polish Jews were rounded up and forced into newly established ghettos at Lodz, Krakow, and Warsaw, to await future plans. Inside these overcrowded walled-in ghettos, tens of thousands died a slow death from hunger and disease amid squalid living conditions. The ghettos soon came under the jurisdiction of Heinrich Himmler, leader of the Nazi SS, Hitler's most trusted and loyal organization, composed of fanatical young men considered racially pure according to Nazi standards.

Jews would be “utilised for work in the East… [The] sexes [will be] separated. Jews capable of work will be moved into these areas as they build roads, during which a large proportion will no doubt drop out through natural reduction. The remnant that eventually remains will require suitable treatment…The evacuated Jews will first be taken, group by group, to so-called transit ghettos, in order to be transported further east from there.”

In July 1938, representatives of 32 countries met in the French town of Evian to discuss the refugee and immigration problems created by the Nazis in Germany. Nothing substantial was done or decided at the Evian Conference, and it became apparent to Hitler that no one wanted the Jews and that he would not meet resistance in instituting his Jewish policies. By the autumn of 1941, Europe was in effect sealed to most legal emigration. The Jews were trapped.
Jews in America responded to the various reports by holding a rally at New York's Madison Square Garden in March 1943 to pressure the U.S. government into action. As a result, the Bermuda Conference was held from April 19-30, with representatives from the U.S. and Britain meeting to discuss the problem of refugees from Nazi-occupied countries. But the meeting resulted in complete inaction concerning the ongoing exterminations.
Dogim backed down; the diggers pressed on. On April 9, Farber announced that they’d reached the roots of a tree near the barbed-wire fence that encircled the camp’s perimeter. Three days later, he made a tentative stab with a makeshift probe he’d fashioned out of copper tubing. Gone was the stench of the pits. “We could feel the fresh April air, and it gave us strength,” he later recalled. “We saw with our own eyes that freedom was near.”
The following year, 1941, would be the turning point. In June, Hitler took a tremendous military gamble by invading the Soviet Union. Before the invasion he had summoned his top generals and told them the attack on Russia would be a ruthless "war of annihilation" targeting Communists and Jews and that normal rules of military conflict were to be utterly ignored.
Anxious to limit immigration to the United States and to maintain good relations with the Vichy government, the State Department actively discouraged diplomats from helping refugees. However, Bingham cooperated in issuing visas and helping refugees escape France. Hiram Bingham gave about 2,000 visas, most of them to well-known personalities, speaking English, including Max Ernst, André Breton, Hannah Arendt, Marc Chagall, Lion Feuchtwanger and Nobel prize winner Otto Meyerhof.
Sophia Litwinska made a sworn affidavit that was entered into the British trial of the SS staff at Bergen-Belsen in the fall of 1945. Some members of the SS staff at Belsen had previously worked at Birkenau and they were on trial for crimes committed at both Birkenau and Belsen. One of the men who was tried by the British was Franz Hoessler, the commander of the women's camp at Birkenau in 1942; he was transferred to Bergen-Belsen in December 1944.
Mengele's work also involved carrying out selections, a task that he chose to perform even when he was not assigned to do so, in the hope of finding subjects for his experiments,[33] with a particular interest in locating sets of twins.[34] In contrast to most of the other SS doctors, who viewed selections as one of their most stressful and unpleasant duties, he undertook the task with a flamboyant air, often smiling or whistling a tune.[35][31] He was also one of the SS doctors responsible for supervising the administration of Zyklon B, the cyanide-based pesticide that was used for the mass killings in the Birkenau gas chambers. He served in this capacity at the gas chambers located in crematoria IV and V.[36]
