Order of the Phoenix

The Order of the Phoenix was a secret society founded by Albus Dumbledore to oppose Lord Voldemort and his Death Eaters. The original Order was created after Voldemort returned to England from abroad and started his campaign to take over the Ministry of Magic and persecute Muggle-borns. The Order worked with the Ministry to oppose the Dark Lord and his followers, and played a crucial role in the First Wizarding War. Victory came with Voldemort's first defeat at the hands of Harry Potter.
