First they came …" is the poetic form of a 1946 post-war confessional prose by the German Lutheran pastor Martin Niemöller (1892–1984). It is about the silence of German intellectuals and certain clergy—including, by his own admission, Niemöller himself—following the Nazis' rise to power and subsequent incremental purging of their chosen targets, group after group.
