Question: who became defense against the dark arts teacher

title: Magic in Harry Potter
text: Defence Against the Dark Arts , commonly shortened to D.A.D.A. , is the class that teaches students defensive techniques to defend against the Dark Arts , and to be protected from Dark creatures . In Harry Potter and the Deathly Hallows , with Death - Eaters in charge of the school , the subject is renamed the Dark Arts , and involves pupils practicing the Cruciatus Curse on those who have earned detentions . The subject has an extraordinarily high turnover of staff members -- throughout the series no Defence Against the Dark Arts teacher has retained the post for more than one school year . Harry is exceptionally skilled in this subject . During the period the story takes place , the class is taught by Quirinus Quirrell ( book one ) , Gilderoy Lockhart ( book two ) , Remus Lupin ( book three ) , Bartemius Crouch Jr impersonating Alastor `` Mad - eye '' Moody ( book four ) , Dolores Umbridge ( book five ) , Severus Snape ( book six ) , and Amycus Carrow ( book seven ) . Hagrid suggests in Harry Potter and the Chamber of Secrets that `` They 're startin ' ter think the job 's jinxed . No one 's lasted long for a while now . '' In Half - Blood Prince , Dumbledore suggests that Voldemort cursed the position because his application for it was rejected . The existence of the jinx was eventually confirmed by Rowling . The position had also been coveted by Snape , but he was denied the position as well . Snape was finally appointed D.A.D.A. professor in Half - Blood Prince . Rowling announced in an interview that once Voldemort had died , the jinx he placed on the office was lifted and a permanent professor had been teaching the subject between the end of Deathly Hallows and the epilogue , set nineteen years afterwards . Furthermore , she imagines that Harry Potter occasionally comes to the class to give lectures on the subject .
