While Dumbledore was putting together the Order of the Phoenix, little did he know that in the Room of Requirement at Hogwarts, Harry, Ron, and Hermione were forming their own resistance. Dumbledore's Army, a name coined by Ginny Weasley in reference to the Ministry's fears about the headmaster, started out as a secret rebellion against Dolores Umbridge, but ended up being a crucial component of the Battle of Hogwarts.
