Dumbledore's Army, excluding harry Potter, Hermione Granger and Ron Weasley.

Dumbledore's Army
, also known as the D.A. or Defence Association, was a secret organisation initiated by Harry Potter, Hermione Granger, and Ron Weasley to teach their fellow Hogwarts students proper Defence Against the Dark Arts in 1995. This organisation was made necessary by the refusal of Dolores Umbridge, the subject's professor during the 19951996 school year, to teach anything in her classes other than textbook theory. It had approximately 28 members. The group was disbanded during the 19961997 school year following the appointment of Severus Snape as Defense Against the Dark Arts teacher, although several members heeded the call and participated in the Battle of the Astronomy Tower at the end of the year.

It was restarted by Neville Longbottom, Ginny Weasley, and Luna Lovegood during the 19971998 school year after Hogwarts fell under the control of Lord Voldemort in order to oppose Death Eaters professors Alecto and Amycus Carrow, who spread propaganda against Muggles and Muggle-borns and taught the Dark Arts. Dumbledore's Army played a vital role during the Second Wizarding War, and members of the organisation fought in the Battle of the Astronomy Tower, and the Battle of Hogwarts.
