It is revealed in "Harry Potter and the Deathly Hallows" that Kingsley is one of the few wizards that the Dursleys seem to like, due to his skill at blending in well with Muggles and his calm, collected demeanour. In that book, Kingsley first appears with other Order members to move Harry from the Dursleys' home to safety in the Burrow. Later in the book, he manages to send a timely warning to Bill and Fleur's wedding using his Patronus, a lynx, when Voldemort overthrows the Ministry of Magic, giving the guests a chance to escape. He continues to guard the Prime Minister but is eventually forced to flee. He later is heard preaching equal rights for Muggles and Wizards on the pirate radio programme ""Potterwatch"" under the pseudonym ""Royal"". In the Battle of Hogwarts, he is first seen organising those who remained to fight. He is later seen dueling an unnamed Death Eater, and ends up duelling Voldemort himself, alongside Minerva McGonagall and Horace Slughorn, but after Bellatrix's death, Voldemort's anger erupts; Kingsley and the two others are defeated (although not killed). Kingsley is appointed temporary Minister for Magic following the death of Voldemort and the deposition of Voldemort's puppet ruler, Pius Thicknesse. However, it was later revealed by Rowling in an interview that Kingsley did become the new Minister permanently, revolutionising the Ministry itself.
