Martin Niemoller was a German Lutheran pastor. He wrote this poem in 1946.
First They Came
First they came for the socialists. And I did not speak out--becsuse I was not a socialist.
Then they came for the trade unionists. And I did not speak out--becsuse I was not a trade unionist.
Then they came for the Jews. And I did not speak out--becsuse I was not a Jew.
Then they came for me--and there was no one left to speak out for me.
