Professor Dolores Jane Umbridge is the central antagonist in the 2003 book Harry Potter and the Order of Phoenix and the 2007 film adaptation of the same name. She also served as a minor, but pivotal, antagonist in Harry Potter and the Deathly Hallows Part 1. She was the senior under-secretary of the Minister of Magic. She was also the Defense Against the Dark Arts Teacher during Harry Potter's fifth year at Hogwarts. She was later promoted as High-Inquisitor and also a temporary headmistress. The reason for her approval as High-Inquisitor was to let the Ministry of Magic take control over Hogwarts. She made several obscure and unfair rules at Hogwarts during her brief leadership.
