A search of the room uncovered the parchment that each member of the D. had signed, entitled "Dumbledore's Army." Finally having what she considered "proof" that Dumbledore was building an army to challenge the Ministry, Umbridge immediately contacted Cornelius Fudge.
During a confrontation with Fudge and Umbridge, Albus Dumbledore took full responsibility for the creation of Dumbledore's Army, to shield Harry and the students from the Ministry's wrath, arguing that the initial overheard discussions about the creation of such a group had taken place before the relevant Education Decree banning such meetings and they had no evidence that any meetings had taken place between then and that evening.
They claimed that Cedric Diggory's death was a "tragic accident", and refused to admit that Voldemort had murdered him.
Concerned that they needed defensive magical skills to combat Lord Voldemort and his Death Eaters, Hermione proposed the formation of a practical study group to be taught by Harry as he had more experience than any of them with using actual defensive and offensive magic following his encounters with Lord Voldemort.
Harry was initially reluctant but, after two weeks of dealing with Umbridge, and her appointment as the first Hogwarts High Inquisitor, he finally agreed.

During the first session, Cho Chang created the name Defence Association, but Ginny Weasley suggested to make the letters DA stand for a different name of their group, Dumbledore's Army, to frighten the Ministry officials, since they were frightened that Dumbledore was creating an army to take over the Ministry;.
Instead, under the stewardship of Dolores Umbridge a Ministry-approved course of theory only would be taught.
Minister for Magic Cornelius Fudge was afraid that Albus Dumbledore could use practical lessons to train an army of wizards and witches to oppose him and to try to take over the Ministry, since he refused to believe that Lord Voldemort had returned.
Kingsley Shacklebolt, an Auror and member of the Order of the Phoenix, used a False memory charm on Marietta to make her version of events tally with Dumbledore's, exploiting the fact that Marietta had only mentioned the meeting this evening rather than revealing the months of classes that had preceded it.
His "confession" led to Fudge attempting to arrest him.
