Pastor Martin Niemoller on the rise of the Nazis in 1930's Germany

They came first for the Communists,
and I didn’t speak up because I wasn’t a Communist.

Then they came for the trade unionists,
and I didn’t speak up because I wasn’t a trade unionist.

Then they came for the Jews,
and I didn’t speak up because I wasn’t a Jew.

Then they came for me,
and by that time no one was left to speak up.
