Antisemitism long had been a feature of the European - particularly but by no means exclusively German - social mindset see:
On Jews and their lies, written by Martin Luther in 1483. Hitler's antisemitism stands out unambiguously in his
Mein Kampf, and in speeches and letters of his predating that. 1n a 1919 letter, he wrote
Quote:"The final goal, however, must stedfastly remain the removal of the Jews altogether."

In this attitude, he was by no means alone, the theme was widely endorsed and strong popular sentiment held Jews responsible for Germany's humiliating defeat in WWI and for economic woes due in fact to the global depression of the 1930s.
Given his own feelings and the social climate of the Germany of the times, antisemitism provided a powerful rally point, making it easy to whip up public support for Hitler's agenda, which centered on establishing Germany as the pre-eminant power on The Continent. Adjunct to Hitler's other aims, what became the "The Final Solution" began to evolve in 1933 with Hitler's rise to power. Over the next 5 years or so, the plight of Germany's Jews became increasingly dire. Ever more restrictive laws were passed, shutting Jews off from German society, depriving them of business and educational opportunities, stripping them of property and inheritances, disenfranchising them, and heaping on them a mounting list of rights from which they were exempted. Vandalism and physical attacks directed against Jewish infrastructure and Jews grew in frequency and intensity, ignored by the authorities and encouraged by Nazi harrangues at meetings and rallies. Over the '35-'38 period large numbers of Jews did emmigrate, more tried but were unable due to increasingly stringent immigration requirements being imposed by nations throughout the world, and many, many more either lacked the resources necessary or believed the horror could neither get worse nor last.
Initially, the idea was forced emmigration, moving the Jews out of Germany. However, increasingly restrictive general immigration controls enacted by many nations (by no means singling out Jews or any other group), largely in response to the economic pressures of the ongoing global depression, rendered deportation an unviable option in the matter of ridding the
Reich and its anticipated conquered territories of Jews.
Perhaps the final trigger was the outcome of the
Evian Conference, a 31-nation conclave convened at the request of then-US-President Franklin Roosevelt in 1938 to come up with a answer to the plight of Jewish refugees worldwide. The conference accomplished little apart from confirming the reluctance of the world's major nations to accommodate an influx of any sort of refugees, Jews or otherwise, but Jews in particular. Though a motion to adopt a resolution condemming Germany's treatment of Jews was proposed, it failed on introduction, never having been given a chance to pass (not to say had it actually gotten out of committee it had a chance of passing anyway).
Hitler saw this as a green light not only to continue but to intensify his anti-Jew agenda. In late 1938, Nazi thugs and hangers-on perpetrated what now is known as
Kristallnacht, a wave of unimagineable anti-Jewish violence and horror which swept German cities, leaving Jewish shops, businesses, schools and temples in ruins, many burned to the ground, and the streets sparkling with the shards of broken glass which gave the night of hateful outrage its name.
Camps for the containment of uprooted Jews long had been established by the time of Germany's September 1939 attack on Poland, and as territory fell into German hands, so too did the Jews living in those territories. The camps' populations swelled beyond the bursting point, and as the war progressed, with seemingly unending German conquest, the swelling stream of dispossessed, forcibly relocated Jews came to overwhelm the Nazi's capability to manage; not only was it impractical to expand existing "resettlement camps" or to build new ones, administering the camps and providing even what little food and care the unfortunate captives were afforded was seen an inconvenient, unnecessary burden on Germany's economy and resources.
In Poland and later in Russia and elsewhere in the East, as the German Army swallowed tens of thousands of square miles of territory, death squads -
Einsatzgruppen - had been formed, initially to deal with intelligentsia, political figures, other community leaders, partisans, and above all else anyone connected with the Communists. Drawn largely from SS units independent of Army control, with a few local Nazi sympathizers here and there as well, these thugs were nothing short of uniformed murderers operating under the direct command of the SS. With the exponential increase of dispossessed, displaced Jews brought on by the successes of the German Army, the practice of executing Jews in place, more or less, as opposed to transporting them to the already strained resettlement camps further and further to the rear as the Army pressed forward, came into vogue - an efficiency measure. Even though the number of death squads was increased dramatically, it became clear the sheer volume of Jews being confined to ghettos or herded into makeshift interim "retransport camps" pending "disposition" called for other measures.
In early 1942, as mentioned earlier by Set, a conference of SS and civilian political leaders was held at
Wansee to lay out the "Final Solution". Lasting not quite an hour and a half, essentially during which Heydrich and other high-ranking SS officers dictated what amounted to the plans already drawn up and approved at the highest levels of Hitler's Nazi machine, while Nazi-installed politicians squabbled over who's Jews were to be dealt with first, the conference's product was the
Wansee Protocol, certainly one of, if not singulary
THE vilest documents with which humankind has disgraced itself throughout history.
Though not documented at Wansee, construction of the death camps was well under way, and mass executions already were being conducted, primarily using exhaust fumes from internal combustion engines as a death agent, disposing of the murdered victims' bodies in open pit mass graves, layers of chemicals being spread over the corpses to hasten decomposition and reduce the stench of decay while the huge pits were filled over a matter of days, covered back with earth when they had reached capacity and new pits opened. Even this was not efficient enough to handle the rising tide of victims. Research and expirimentation in the interest of streamlining the process shortly came up with the cyanide gas chambers and the production-line crematoria which served in several locations till the end of the war, murdering thousands of people a day, every day, month after month after month.
Now for the short answer - Why did Hitler kill the Jews? Simple; because the world, not wishing to get involved, refusing to address the reality it preferred to not face, sat aloofly by, doing nothing about the problem untill it was far too late to do anything.
