Who were the Defense Against the Dark Arts teachers in the Harry Potter series?


assistant
While Harry Potter was a student, there were six Defense Against the Dark Arts teachers while he was at Hogwarts. They are Quirinus Quirrell, Gilderoy Lockhart, Remus Lupin, Alastor 'Mad Eye' Moody (who was impersonated for a good chunk of the year by Bartemius Crouch Jr), Dolores Umbridge, and Severus Snape. The final year of the book series, when Harry Potter was no longer in the school, the position of Defense Against the Dark Arts was held by Amycus Carrow. Athough he mostly taught the Dark Arts, not the defense against them.
