The Order of the Phoenix was a secret society founded by Albus Dumbledore first in 1976 and then again in June of 1995, with the express purpose of fighting Lord Voldemort and his Death Eaters. It was comprised only of overage wizards, as it was believed those below the age of seventeen would be unable to cope with the dangers involved.
