The Ministry of Magic is the governing body for the magical community in Great Britain. It oversees various aspects of magical society, including law enforcement, magical transportation, and the regulation of magical creatures. The Ministry is divided into several departments, each responsible for specific areas, such as the Department of Magical Law Enforcement and the Department for the Regulation and Control of Magical Creatures.
Located in London, the Ministry is hidden from non-magical people, or Muggles, to maintain secrecy. It is depicted in the Harry Potter series as a complex organization with a mix of competent and corrupt officials, reflecting the challenges of governing a diverse magical population.
