When you hear the phrase 10 infamous witch hunters, you might picture shadowy figures lurking in foggy forests. In reality, these were real people whose zeal, greed, or thirst for power led to the torture and execution of countless innocents. Below we rank the ten most notorious witch‑hunters, from charismatic preachers to ruthless magistrates, and unpack the gruesome details of their campaigns.
10 Georg Scherer
Vienna rarely appears in discussions of witchcraft, and for good reason: its record holds a single, stark case – the Plainacher Witch Affair of 1583. The accused was 70‑year‑old Elisabeth “Elsa” Plainacher, who raised her granddaughter Anna in Mank, Lower Austria. After Anna reached adulthood, she began suffering seizures, likely due to undiagnosed epilepsy.
Enter Georg Scherer, a magnetic yet fanatically Catholic pulpit orator convinced that witches deserved death. Scherer quickly declared Anna a victim of a hex and, after a perfunctory “investigation,” blamed Elsa, noting that she was a Lutheran – a detail that only inflamed his prejudice. Through relentless “interrogation,” Anna was persuaded that her grandmother was the source of the curse. Elsa was then seized, subjected to brutal torture, and eventually confessed to witchcraft, sealing her fate.
Even the mayor of Vienna appealed to the emperor to halt the execution, but Scherer’s ecclesiastical clout outweighed civic pleas. On September 28, 1583, Elsa Plainacher was burned at the stake, a grim testament to Scherer’s unchecked influence.
9 Matthew Hopkins
In the roster of witch‑hunters, Matthew Hopkins earned the nickname “Witch‑Finder General” and is credited with overseeing roughly 200 witchcraft cases. Little is known about his early life, but by the 1620s he had failed as a lawyer and turned to witch‑hunting as a lucrative sideline. Money, rather than pure fanaticism, appears to have driven his pursuits.
England’s witch laws were comparatively lax yet still permitted cruelty. Hopkins employed sleep deprivation to wear down suspects, forcing them to wander all night until exhaustion broke their resolve. He also used the infamous “ducking” method: binding the accused and plunging them into water. The logic was that a true witch, having renounced baptism, would float, while an innocent would sink and die, thus achieving a heavenly ascent.
Hopkins’s later years fade into obscurity. Eventually, clergy grew weary of his overzealous tactics, and his influence waned. Folklore even suggests he was once subjected to his own ducking test after being accused of witchcraft himself.
8 Sebastian Michaelis
Grand inquisitor Sebastian Michaelis served the French Inquisition during the late 16th and early 17th centuries. He is best remembered for authoring The Admirable History of Possession and Conversion of a Penitent Woman (1612), a work that famously catalogues a hierarchy of demons – Lucifer, Beelzebub, Leviathan, and Asmodeus – claimed to be gleaned from direct demonic testimony during a notorious possession case.
The drama unfolded in 1611 at Aix‑en‑Provence, where several Ursuline nuns reported demonic possession. Michaelis, already feared for sending 18 witches to their deaths, was summoned. A young nun, Madeleine de Demandolx de la Palud, accused local priest Father Gaufridi of forging a pact with the Devil and committing sexual perversions while she was possessed. Soon, more nuns claimed similar afflictions.
Michaelis ordered exorcisms and, despite lacking physical evidence, accepted the “possessed” nuns’ testimonies – a groundbreaking move in France at the time. Father Gaufridi was ultimately burned at the stake, cementing Michaelis’s reputation as a relentless witch‑hunter.
7 Pierre De Lancre
Pierre de Lancre epitomizes the worst‑case scenario when a fanatical witch‑hunter wields unchecked authority. In 1609, the Labourd province of France – a cultural crossroads of Basque, Spanish, and French peoples – was plagued by a surge of witch accusations, occasionally erupting into violence.
King Henry IV appointed the Bordeaux judge, Pierre de Lancre, to restore order. Empowered by royal backing, Lancre launched a ruthless campaign, executing dozens of alleged witches within a mere four months. Some estimates place the death toll as high as 80, though Lancre himself claimed thousands more were active in the region.
His bloodthirsty reign eventually drew criticism, leading to his dismissal. Afterwards, Lancre authored three treatises outlining his perceived signs of witchcraft, which bizarrely included indecent dancing, swearing, overeating, and keeping toads or lizards as pets.
6 Balthasar Von Dernbach
Balthasar von Dernbach was a 16th‑century Benedictine monk who rose to become prince‑abbot of the Fulda monastery. Sent there at age 12, he progressed through the hierarchy until succeeding his uncle as abbot.
From the outset, Dernbach imposed a harsh Counter‑Reformation agenda, forcing subjects back into Catholicism. His policies sparked revolt, prompting his temporary abdication. After a 25‑year exile, he reclaimed his position in 1602 and turned his fury toward witchcraft, igniting one of the largest witch‑trials in history.
Among the early victims was Merga Bien, a German heiress forced to confess she bore the Devil’s child and murdered her first husband. Over 200 individuals followed her fate. Dernbach enlisted Balthasar Nuss to oversee the trials, both sharing a fanatical hatred of witches. After Dernbach’s death in 1605, the trials ceased, and Nuss was later arrested, tried, and beheaded for exploiting the hysteria for personal gain.
5 Peter Binsfeld
Peter Binsfeld, a 16th‑century German theologian, rose to prominence as a leading authority on witchcraft. Serving as auxiliary bishop of Trier, he worked closely with Archbishop Johann von Schonenberg during the infamous Trier witch trials (1587‑1593). His reputation as a fervent witch‑hunter inspired him to pen Treatise on the Confessions of Evildoers and Witches, a text that spread widely across Europe.
Binsfeld argued that witchcraft deserved the special legal category crimen exceptum, exempting it from standard investigative safeguards. He championed torture, deeming ordinary methods insufficient, and even advocated torturing children. Moreover, he encouraged individuals to accuse their own family members, insisting that such denunciations saved souls.
Opposition was swiftly silenced; dissenters were branded heretics. One notable critic, Cornelius Loos of Trier, had his anti‑Binsfeld manuscripts confiscated and was imprisoned, illustrating the terrifying reach of Binsfeld’s influence.
4 Nicholas Remy
Nicholas Remy, a 16th‑century French magistrate, boasts the dubious claim of having prosecuted over 900 witches – a figure that modern scholars doubt due to missing court records. Remy himself documented detailed accounts for 128 individuals, a more plausible number.
Originally a lawyer with a side career as a historian, Remy’s obsession with witchcraft allegedly began after his eldest son died, which he blamed on a local beggar’s curse. This personal vendetta propelled him upward: he was ennobled in 1583 and appointed procureur‑general of the Duchy of Lorraine in 1591.
When not hunting witches, Remy authored Demonolatry (1595), a best‑selling manual that argued witchcraft ran in families, urging the eradication of entire bloodlines. His work cemented a terrifying doctrine that persisted throughout Europe.
3 Alonso De Salazar Frias
Alonso de Salazar Frias earned the moniker “Witches’ Advocate” despite being a Spanish inquisitor involved in the massive Navarre witch hunt of the early 17th century. While he believed in witchcraft and its punishment, he opposed the automatic execution of every accused.
The hysteria in Navarre followed Pierre de Lancre’s French witch‑hunt, inflating fears of a sprawling Basque coven. Salazar, one of three inquisitors on the tribunal, grew skeptical of the sheer numbers – his notes listed over 7,000 denounced or self‑confessed witches.
Salazar championed unprecedented reforms: he barred children’s confessions entirely and insisted that mere accusation or confession was insufficient proof. Consequently, only 31 individuals were convicted, with roughly a dozen burned at the stake, a stark contrast to the thousands originally alleged.
2 Roger Nowell
The Pendle Hill trials of 1612, often dubbed England’s “Salem,” saw ten people executed and set a precedent that rippled into the famous Salem witch trials. Prior to this, children under fourteen were deemed unreliable witnesses, but King James I suspended that rule for witch cases.
Roger Nowell, the local magistrate, seized upon the case of a dead merchant allegedly cursed by a witch for refusing to sell her pins. The accused, a woman named Demdike, was both a witch and a Catholic – a combination that appealed to James’s anti‑Catholic sentiment. Nowell saw the trial as a career‑boosting opportunity.
Utilizing the testimony of nine‑year‑old Jennet Device, Nowell secured convictions against eleven people, including members of Jennet’s own family. Ten of the accused were executed or perished in prison. The proceedings were chronicled by court clerk Thomas Potts in The Wonderful Discoverie of Witches in the Countie of Lancaster.
1 Johann Von Schonenberg
Johann von Schonenberg, archbishop‑elector of Trier, orchestrated the most extensive witch‑trial in European history. In the late 1500s, the Trier region suffered persistent sterility issues, prompting authorities to blame witchcraft.
Schonenberg launched an unprecedented campaign, interrogating every township within his diocese. No one – judges, priests, councilors, or deans – escaped scrutiny. Those not executed faced confiscation of assets, exile, and the loss of their children’s futures. The trials spanned from 1581 to 1593, resulting in 368 executions in Trier alone and countless undocumented deaths throughout the diocese.
Holding a seat in the Holy Roman Empire’s electoral college, Schonenberg wielded immense power, using it to purge perceived undesirables – witches, Jews, and Protestants alike. By 1593 the region lay devastated, its population decimated, marking the grim end of Schonenberg’s reign of terror.
These ten figures illustrate how personal ambition, religious fervor, and societal fear combined to fuel some of history’s darkest chapters. Their legacies remind us that the line between justice and hysteria can be perilously thin.
