Harry James Potter (b. 31 July 1980) was a half-blood wizard, the only child and son of James Potter and Lily Potter (née Evans), and one of the most famous wizards of modern times. In what proved to be a vain attempt to circumvent a prophecy that a boy born at the end of July of 1980 could be able to defeat him, Voldemort attempted to murder him when he was a year and three months old, shortly after murdering Harry's parents as they tried to protect him. This early, unsuccessful attempt to vanquish Harry led to Voldemort's first defeat and the end of the First Wizarding War. One consequence of Lily's protection is that her orphaned son had to be raised by her only remaining blood relative, Petunia Dursley, where he was neither welcomed nor nurtured, but would stay alive, at least until he was seventeen years old. As the only known survivor of the Killing Curse up to that point, Harry was already famous before he arrived at Hogwarts School of Witchcraft and Wizardry.
Early on his eleventh birthday, Harry learned that he was a wizard. He began attending Hogwarts in 1991 and was Sorted into Gryffindor house. While at school, Harry became best friends with Ronald Weasley and Hermione Granger, later he became the youngest Quidditch Seeker in over a century and eventually captain of his house's team, winning two Quidditch Cups. He became even better known in his early years for protecting the Philosopher's Stone from Voldemort and saving Ron's sister Ginny Weasley from the Chamber of Secrets. In his fourth year, Harry won the Triwizard Tournament, although the competition ended in tragedy with the death of Cedric Diggory and the return of Voldemort. The next school year, Harry reluctantly founded Dumbledore's Army and fought in the Battle of the Department of Mysteries, during which he lost his godfather, Sirius Black, who was a father figure to him.
