During the Twentieth Century, the wizarding community deals with two major conflicts, each of which is instigated by a Dark Wizard of prodigious power. In each of these conflicts, the risk of exposure to the Muggles is great. And in each case, one person stands in the end against evil and is victorious: Dumbledore over Grindelwald in 1945 and Harry Potter over Voldemort in 1998. After the second of these uprisings, the Ministry of Magic is reorganized and improved as the Twenty-First Century dawns.
