Gellert Grindelwald (c. 1883 - March, 1998) was considered one of the most dangerous Dark Wizards of all time, second only to Lord Voldemort. A student at Durmstrang Institute, Grindelwald was expelled for conducting twisted, dark experiments. He later fostered a friendship with a young Albus Dumbledore, making plans to find the Deathly Hallows and lead a Wizarding revolution to end the International Statute of Secrecy, creating a benevolent global hierarchical order led by wise and powerful witches and wizards that dominated Muggles. Their partnership fell apart after the two were involved in a three-way duel with Aberforth Dumbledore that resulted in the death of Ariana Dumbledore. Grindelwald left Britain and later stole the Elder Wand from Mykew Gregorovitch, proceeding alone with the revolution he and Dumbledore had planned.
