Editing Albus Dumbledore (section)

===''Harry Potter and the Order of the Phoenix''===
Dumbledore appears in the fifth novel in the series, ''[[Harry Potter and the Order of the Phoenix]]'' (2003). He is removed from his position as Chief Warlock of the [[Wizengamot]], voted out of the Chairmanship of the International Confederation of Wizards, and is almost stripped of his Order of Merlin First Class due to his speeches regarding the return of Voldemort. Meanwhile, the Ministry of Magic attempts to discredit him and Harry, often through the ''[[Daily Prophet]]''. Dumbledore enrages [[Minister for Magic]] [[Cornelius Fudge]] when he intercedes at a hearing to prevent Harry from being expelled from Hogwarts.

The Ministry passes Educational Decree Twenty-two, which allows Fudge to appoint [[Dolores Umbridge]] as the professor of [[Defence Against the Dark Arts]]. Through her, Fudge gradually gains power over Hogwarts and Dumbledore, whom he fears is amassing an underage wizard army to overthrow the Ministry. Umbridge forbids students from practicing defensive spells in her class, which prompts Harry, Ron, and Hermione to form a secret practice group called [[Dumbledore's Army]]. When the Ministry discovers the group, Dumbledore shields his students from punishment by falsely claiming that it was his idea. He is removed from the position of headmaster for the second time.

When the [[Order of the Phoenix (fictional organisation)|Order of the Phoenix]] battles Voldemort's [[Death Eaters]] in the [[Department of Mysteries]], Dumbledore arrives to aid them. He subdues most of the Death Eaters and binds them with an Anti-Disapparition Jinx to prevent them from escaping. He then engages in a duel with Voldemort, who tries to possess Harry so Dumbledore will kill him. After this ruse fails, Voldemort is forced to flee with [[Bellatrix Lestrange]]. Several Ministry officials witness the end of the battle, which leads to Dumbledore being reinstated as headmaster. Dumbledore explains to Harry that Voldemort chose Harry as his equal, and that either he or Voldemort must eventually kill the other.
