Today, the world marks International Holocaust Remembrance Day, a symbolic date to commemorate the victims of Nazism.

Millions were targeted for reasons of biology, nationality, or political ideology. But few people know that the Nazis’ victims included thousands of Jehovah’s Witnesses, who suffered for their Christian faith.

Jehovah’s Witnesses, also then known as Bible Students, were “the only group in the Third Reich to be persecuted on the basis of their religious beliefs alone,” according to Professor Robert Gerwarth.

The Nazi regime branded Witnesses “enemies of the State,” according to historian Christine King, because of “their very public refusal to accept even the smallest elements of [Nazism], which didn’t fit their faith and their beliefs.”

On religious grounds, the politically neutral Witnesses refused to give the “Heil Hitler” salute, take part in racist and violent acts, or join the German army. Moreover, “in their literature they publicly identified the evils of the regime, including what was happening to the Jews,” according to King.

Witnesses were among the first sent to concentration camps, where they bore a unique uniform symbol—the purple triangle. Of about 35,000 Witnesses in Nazi-occupied Europe, more than one-third suffered direct persecution.

Most were arrested and imprisoned. Hundreds of their children were taken to Nazi homes or reformatories. About 4,200 Witnesses went to Nazi concentration camps.

Leading authority Detlef Garbe wrote: “The declared intention of the NS [Nazi] rulers was to completely eliminate the Bible Students from German history.”

An estimated 1,600 Witnesses died, 370 by execution.

The Nazis sought to break Witnesses’ religious convictions by offering them freedom in exchange for a pledge of obedience.

The standard Erklärung (issued beginning in 1938) required the signee to renounce his or her faith, denounce other Witnesses to the police, fully submit to the Nazi government, and defend the “Fatherland” with weapon in hand. Prison and camp officials often used torture and privation to induce Witnesses to sign.

According to Garbe, “extremely low numbers” of Witnesses recanted their faith.

Geneviève de Gaulle, a niece of General Charles de Gaulle and member of the French Resistance, said of female Witness prisoners in Ravensbrück concentration camp: “What I admired a lot in them was that they could have left at any time just by signing a renunciation of their faith. . . . Ultimately, these women, who appeared to be so weak and worn out, were stronger than the SS, who had power and all the means at their disposal. They had their strength, and it was their willpower that no one could beat.”

The failure of Nazi coercion in the case of Jehovah’s Witnesses contrasts with widespread societal conformity to Nazi aims before and during the Holocaust.

The nonviolent resistance of ordinary people to racism, extreme nationalism, and violence merits thoughtful reflection on this International Holocaust Remembrance Day.
