The Ministry of Magic is the government of the Magical community of Britain in J. K. Rowling's Wizarding World, headed by an official entitled the Minister for Magic. The magical government in Britain is first mentioned in Harry Potter and the Philosopher's Stone; the Ministry makes its first proper appearance in Harry Potter and the Order of the Phoenix (2003). Throughout the books, it is regularly depicted as corrupt, elitist and completely incompetent, with its high-ranking officials blind to ominous events and unwilling to take action against threats to wizard society. In Order of the Phoenix, Dolores Umbridge was placed at Hogwarts to observe the happenings within the school, and prevent the spread of news concerning the return of Lord Voldemort. It reaches a zenith of corruption, before being effectively taken over by Voldemort. At the end of the final book, following Voldemort's death, Kingsley Shacklebolt is revealed to have become the Minister for Magic.
