What Is The Order Of The Harry Potter Series?

The Order of the Phoenix is a group of people that together fight against Lord Voldemort and his Death Eaters because they don't want to turn to their side, and instead, are against the reign of terror that Tom Marvolo Riddle (Lord Voldemort) was trying to achieve by taking over the Wizarding World.
