By 1933 almost 20,000 Jehovah's Witnesses were active in Germany, going door to door as preachers in a country where the Nazi regime had just taken power. The regime targeted them specifically, not incidentally, for a refusal rooted in their own religious conviction: they would not swear loyalty oaths to the state and would not serve in its armed forces, a stance the regime treated as defiance rather than conscience.
That refusal marked them inside the camp system itself. Witnesses sent to concentration camps were identified there by a purple triangle badge, a marker unique to them among the regime's prisoner classifications. The sources this account draws on give inconsistent figures for the scale of what followed, estimates of those sent to camps ranging from 2,000 to 10,000 and of deaths in custody ranging from 1,200 to 5,000, including 250 executed, a genuine disagreement this account states rather than resolves into one invented number.
What Nazi persecution changed for Jehovah's Witnesses was the imposition of a distinct identity under duress, marked, imprisoned and killed specifically for a conscientious refusal that the regime treated as sufficient grounds on its own, regardless of the uncertain final count of who paid for it with their life.
