On 1 August, 1997, Lord Voldemort and his Death Eaters took over the Ministry of Magic. Minister for Magic Rufus Scrimgeour was tortured and then killed, the Imperius Cursed Pius Thicknesse was installed as a puppet in his place, and the Death Eaters began a campaign against their enemies, notably Muggle-borns. They were ordered to register with the Muggle-Born Registration Commission, which convicted them of stealing magic from "real" wizards and witches (pure-bloods) and imprisoned them in Azkaban, though the entire trial was unfair and Muggle-borns were punished whether the evidence proved them guilty or not. Some were threatened with the Dementor's Kiss, some were imprisoned, and some were stripped of their wands and jobs, and reduced to being street beggars. Those who refused to register, such as Ted Tonks, were pursued by Snatchers, sometimes fatally. Dolores Umbridge, in her position as the Head of this department, enjoyed her newfound authority and sadistically tormented the many Muggle-borns; she assigned many of her subordinates to produce anti-Muggle pamphlets in an autonomous manner, and seemed rather unpopular due to her tyrannical and sadistic manner.
- The head of the Commission conducted the trials and directed the efforts to round up Muggle-borns, which was performed by Snatchers.
- Oversaw the creation of pamphlets and similar propaganda to alert the magical community to the dangers of Muggle-borns. One such pamphlet showed a rose with a frown on its face, representing pure-bloods and a weed choking the flower, representing the Muggle-borns. The title of this particular pamphlet was Mudbloods and the Dangers They Pose to a Peaceful Pure-Blood Society.
