John Chrysostom, an influential Church Father and Bishop of Antioch, delivered a series of sermons in which he described Jews as "wild beasts" and enemies of Christianity. These sermons helped establish a theological foundation for Christian antisemitism in Europe that endured for centuries. "Wild beasts who murder their own offspring….. and worship the avenging devils who are the foes of our life." (Pulzer 17) -
Throughout the Crusades, Christian armies massacred Jewish communities, especially in the Rhineland cities of Mainz, Worms, and Speyer. These mass killings, often sanctioned by local leaders or church figures, marked some of the first large-scale, religiously motivated slaughters of Jews in Europe. "The First Crusade (1096) was accompanied by massacres of Jews and attempts at forced conversion in the Rhineland." (Pulzer 17)

-
German journalist Wilhelm Marr coined the term "antisemitism" to give a pseudoscientific and ideological veneer to anti-Jewish prejudice. His writings helped shift antisemitism from religious to racial and political hostility, influencing later nationalist and Nazi thought. "It was used for the first time in a small book-which became very popular- called The Triumph of Jewry Over Germanism, by Wilhelm Marr. That marked an important change in the history of Jewish persecution."(Rogasky 10)

"Hitler was so impressed by the Protocols that he declared the Nazis could learn a lot about gaining power from its contents." (Rogaky 11) -
In 1923, Germany experienced hyperinflation, with the value of the mark collapsing and ordinary goods costing billions. The crisis led to widespread unemployment and poverty, setting the stage for political instability and radical solutions. "The inflation grew so fast it might cost twice that in the evening. One American cent was worth 1.66 million reichsmarks." (Rogasky 12)

During the Weimar era and especially as Nazi influence grew, Jews were gradually excluded from journalism, law, medicine, and military service. These occupational bans laid the groundwork for the racial laws of the 1930s.
-
President Paul von Hindenburg appointed Adolf Hitler Chancellor, believing he could be controlled within a conservative cabinet. Instead, Hitler quickly consolidated power and dismantled democratic institutions. "Once he was appointed chancellor, Hitler began to dismantle democratic practices in Germany, thus beginning the reign of devastation that would flow from Germany throughout Europe until the end of World War II." (“Rumblings of Danger” 1) -
Just weeks after taking power, the Nazis opened Dachau near Munich as the first official concentration camp.

-
After the death of President Hindenburg, Hitler merged the offices of Chancellor and President and declared himself Führer, or supreme leader. This completed his consolidation of absolute power in Germany. -
At the annual Nazi Party rally in Nuremberg, Hitler introduced two major laws: the Reich Citizenship Law and the Law for the Protection of German Blood and Honor. These laws stripped Jews of German citizenship and outlawed marriage and sexual relations between Jews and non-Jews. "In 1935, attacks against Jews escalated. On September 15, the Nuremberg Race Laws were enacted, stripping German Jews of their citizenship and depriving them of all of their political rights."(“Rumblings of Danger” 2)
-
Nazi authorities began expelling Jews from Germany and Austria, dumping them at the Polish border in inhumane conditions without shelter or resources. These deportations were the first efforts to forcibly remove Jews from the Reich and foreshadowed later mass transports.
-
Following the assassination of a German diplomat by a Jewish teenager in Paris, Nazi leaders unleashed a wave of coordinated violence against Jews across Germany and Austria. Over 1,400 synagogues were burned, 7,500 businesses were destroyed, and 30,000 Jewish men were arrested and sent to camps. "We were paralyzed by fear. It was not just a normal fear of reprisals. The year 1938 had been the worst so far, one anti-Jewish decree had followed on the heel of the other." (Weinberg 35)

Germany launched a massive invasion of Poland using blitzkrieg tactics, beginning World War II in Europe. This also marked the beginning of full-scale antisemitic terror under military occupation, targeting the 3 million Jews living in Poland. -
As Soviet forces advanced, the SS began evacuating camps, forcing tens of thousands of prisoners on death marches in freezing winter conditions. Thousands died from exhaustion, starvation, or execution along the way. "One day, I saw a death march. They pushed the people like cattle through the middle of the town. And the Gestapo was kicking and pushing those who walked too slowly or that were not in line." (Opdyke 448)

German authorities finalized the construction of the Warsaw Ghetto, walling in over 400,000 Jews in overcrowded, unsanitary conditions. This became the largest ghetto in Nazi-occupied Europe and a central site of suffering, resistance, and later deportation.
-
As part of the T4 euthanasia program, Nazi doctors conducted lethal gas experiments using carbon monoxide in sealed rooms to kill the disabled. These early tests laid the technical foundation for the gas chambers used in extermination camps.
-
Thousands of Jews from the Warsaw Ghetto were deported to forced labor camps and killing centers. Deportations would intensify in 1942 with the opening of extermination camps like Treblinka.
-
The SS tested mobile gas vans, in which victims were locked in the back and asphyxiated with exhaust fumes. These vans were first used in occupied Poland and would later become a common method of mass murder.
-
Part of the “Final Solution” planning. The Nazis began to destroy the ghettos and remove all Jews that lived in them.
-
Inspired by the Warsaw Ghetto Uprising, Zionist and socialist youth groups began organizing underground cells and stockpiling weapons. These networks played key roles in later revolts in places like Vilna, Bialystok, and Auschwitz.

-
On the eve of Passover, Jewish resistance fighters in the Warsaw Ghetto launched an armed revolt against German forces sent to deport the remaining inhabitants. The uprising lasted nearly a month, becoming the most famous act of Jewish resistance during the Holocaust. "It was not the usual gunfire one heard from the ghetto; this time the bursts were deafening. Powerful detonations made the earth tremble." (Meed 326)
-
After years of resistance, many Jewish underground movements were crushed by Nazi crackdowns or suffered from overwhelming losses. Despite their destruction, their efforts are remembered as acts of extraordinary courage in the face of genocide.
-
The Nazis destroyed evidence of crimes by demolishing camps and killing remaining prisoners before liberation. Many survivors were left in horrific conditions when Allied forces finally arrived.
-
Sonderkommando prisoners blew up Crematorium IV using explosives smuggled in by female prisoners. Though quickly crushed, the revolt killed several SS guards and became a powerful symbol of defiance. -
