Over the course of the "Harry Potter" books, Hagrid is expelled from Hogwarts after The Ministry of Magic thought he had opened the Chamber of Secrets. But the truth that he had been framed by Tom Riddle is exposed and Hagrid is allowed to remain at the school as gamekeeper. The government broke his wand and banned him from doing magic when he was expelled, but he keeps pieces of the wand in his pink umbrella.
