The Harry Potter franchise owes its popularity thanks to its complex storyline and incredibly detailed world-building. And much like in the real world, the magical world of Harry Potter has a primary governing body, the Ministry of Magic. The Minister for Magic is the head of the Ministry and the equivalent of the Prime Minister in Great Britain. During most of Harry Potter, Ron Weasley, and Hermione Granger's time at Hogwarts, Cornelius Fudge was the Minister for Magic.
