Was Martin Luther a Hero or Villain? YOU Be the Judge!History tends to judge historical figures in extremes: Genghis Khan was a barbarian! Alexander the Great WAS great! As teachers, it's tempting at times to present the world as black and white to our students: good or evil, friend or foe, hero or villain. Use this Martin Luther mini-poster to encourage students to take off the rose-colored glasses and see beyond the established historical narratives, into the real world of gray. ©2017.
