Despite the Order’s best efforts, Voldemort continued to grow in magical power and influence, and his attacks, whether carried out personally or by his Death Eaters, became more frequent and brutal. It was clear that Dumbledore was the only wizard in the world who rivalled Voldemort in ability. The nascent Order of the Phoenix initially had very little success, and many continued to be killed by Voldemort. Terror and chaos gripped the populace of wizarding Britain to the point that many began to fear to speak Voldemort's name. He became widely referred to as "He Who Must Not Be Named," or, less formally, "You Know Who" within the first year of his reign. Numerous ordinary witches and wizards (such as Mr. Thomas and Robert McGonagall Jr.) lost their lives, and the Death Eaters frequently cast the Dark Mark over the scenes of their murders. To protect the organisation, Voldemort ensured that Death Eaters did not know the identities of too many of their fellows, and, to society at large, their identities were completely unknown.[13] Increasing the confusion and paranoia even further, Voldemort placed many dozens of innocent victims under the Imperius Curse simulaniously, and forced them to carry out his orders. Even friends and family members were not above suspicion of one another.
