The Head of the Muggle-Born Registration Commission was a position of power within the Ministry of Magic for a short amount of time. It was created along with the Muggle-Born Registration Commission when Lord Voldemort was indirectly in control of the Ministry during the height of the Second Wizarding War, and is the leading power within this organisation. The only head of the Muggle-Born Registration Commission was Dolores Umbridge, the founder of the commission. It was never intended to be a permanent committee; however, former members were recognised for being part of the Commission.
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 position was eliminated after Voldemort was killed by Harry Potter and the Commission was disbanded in May of 1998, its Head arrested, trialled and jailed in Azkaban for crimes against Muggle-borns, some of whom did not survive the ordeals of the prison themselves.
- 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.
