The Wizarding World was built on war long before Harry Potter ever arrived. From the ancient Muggle conflicts that exposed magic to the Goblin rebellions and Giant uprisings, every generation has fought to survive its own chaos. Then came Grindelwald’s global war—and Voldemort’s two reigns of terror that nearly ended wizardkind. In this lesson, we uncover all five Wizarding Wars in Harry Potter—the Muggle War, Goblin War, Giants’ War, Grindelwald’s revolution, and Voldemort’s First and Second Wars. Learn how bloodlines, Dark Arts, and forbidden spells shaped centuries of fear… and why peace in the Wizarding World has always been an illusion. — Professor Severus Snape
