what caused the jewish holocaust (Europe 1934-45)?

Pride and revenge on the part of the ultra-nationalist German. One can not say that the U.S. government is not jointly and severally liable, as humiliated the government of another country before the second world war.

I got this from the source i listed below. If you wanna learn more, and also see testimonies, pictures, videos, look into that site.

"In the modern period, antisemitism that emphasized economic, social or political differences gained strength. A combination of racial antisemitism and social Darwinism, however, invested this traditional antisemitism with a new and dynamic image. Racial theories became prevalent in Europe and, especially in Germany in the middle of the nineteenth century. The very term “antisemitism”, which signals antipathy towards Jews not as practitioners of a different faith or holders of a separate nationality, but as members of a special race, was first coined by antisemites in Germany in the 1870s.

Not until the 1930s, however, with the ascendancy of National Socialism and Adolf Hitler’s accession to power in Germany, did racial antisemitism become a political instrument in the hands of the masses and, later on, the official policy of a modern state. From then on the essence of Jewishness was believed to be biological. In the past a Jew could theoretically avoid persecution by assimilating, renouncing the customs of his tradition, or adopting a non-Jewish faith. However, the racial element eliminated these possibilities. The new racial outlook defined the German people as the finest and purest branch of the Aryan-Nordic race (along with the Nordic-Scandinavian peoples) and labeled Jews as a subhuman race that strove to challenge the “correct” world order and deprive the “supreme race” of its position of dominance and leadership. Unless the “Aryan” race won the struggle and established its dominion, Jews would bring about the extermination of the human race."

The Nazis persecuted the Jews based on a false concept of race,racial antisemitism.Racial antisemitism is an outgrowth of religious antisemitism where Jews were unfairly blamed for the death of Jesus,the Jews did not kill Jesus it was the Roman high officials

One man - Hitler.
