First, They Came for the Socialists

First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the trade unionists, and I did not speak out—because I was not a trade unionist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.
—Martin Niemöller
This quote is attributed to the prominent German pastor Martin Niemöller. It is sometimes mistakenly referred to as a poem. 
After World War II, Niemöller openly spoke about his own early complicity in Nazism and his eventual change of heart. His powerful words about guilt and responsibility still resonate today.
