Truslow Review of Watt and Wiesner on the Reformation from the College Board European History book review section (two books reviewed). Witchcraft and the Long Reformation
The exact text of what Martin Niemoller said, and which appears in the Congressional Record, October 14, 1968, page 31636 is:
"When Hitler attacked the Jews, I was not a Jew, therefore I was not concerned. And when Hitler attacked the Catholics, I was not a Catholic, and therefore, I was not concerned. And when Hitler attacked the unions and the industrialists, I was not a member of the unions and I was not concerned. Then Hitler attacked me and the Protestant church -- and there was nobody left to be concerned."
