But Professor Umbridge's "Ministry-approved" course of defensive magic leaves the young wizards woefully unprepared to defend themselves against the Dark forces threatening them, so at the prompting of his friends Hermione and Ron, Harry is convinced to take matters into his own hands.

Meeting secretly with a small group of students who name themselves "Dumbledore's Army," Harry teaches them how to defend themselves against the Dark Arts, preparing the courageous young wizards for the extraordinary battle that lies ahead.
