On December 5th, 1484, Pope Innocent VIII issued an edict (Bull) entitled Summis desiderantes affectibus alleging that many men and women were in collusion with the Devil. All Christians were required to assist the two Dominican monks, Jacob Sprenger and Heinrich Kramer, placed in charge of handling this supposed Witchcraft problem.
Pope Innocent VIII put Sprenger and Kramer in charge of seeking out and fighting people who supposedly in association with Satan to cause disease and pestilence, harm harvests and cattle, and perpetuate other heinous crimes.

Innocent VIII: BULL Summis desiderantes, Dec. 5th, 1484
Bullarium Romanum (Taurinensis editio), sub, anno 1484.
Innocent, bishop, servant of the servants of God, Ad futuram rei memoriam
Desiring with supreme ardor, as pastoral solicitude requires, that the catholic faith in our days everywhere grow and flourish as much as possible, and that all heretical depravity be put far from the territories of the faithful, we freely declare and anew decree this by which our pious desire may be fulfilled, and, all errors being rooted out by our toil as with the hoe of a wise laborer, zeal and devotion to this faith may take deeper hold on the hearts of the faithful themselves.
It has recently come to our ears, not without great pain to us, that in some parts of upper Germany, as well as in the provinces, cities, territories, regions, and dioceses of Mainz, Ko1n, Trier, Salzburg, and Bremen, many persons of both sexes, heedless of their own salvation and forsaking the catholic faith, give themselves over to devils male and female, and by their incantations, charms, and conjurings, and by other abominable superstitions and sortileges, offences, crimes, and misdeeds, ruin and cause to perish the offspring of women, the foal of animals, the products of the earth, the grapes of vines, and the fruits of trees, as well as men and women, cattle and flocks and herds and animals of every kind, vineyards also and orchards, meadows, pastures, harvests, grains and other fruits of the earth; that they afflict and torture with dire pains and anguish, both internal and external, these men, women, cattle, flocks, herds, and animals, and hinder men from begetting and women from conceiving, and prevent all consummation of marriage; that, moreover, they deny with sacrilegious lips the faith they . received in holy baptism; and that, at the instigation of the enemy of mankind, they do not fear to commit and perpetrate many other abominable offences and crimes, at the risk of their own souls, to the insult of the divine majesty and to the pernicious example and scandal of multitudes. And, although our beloved sons Henricus Institoris and Jacobus Sprenger, of the order of Friars Preachers, professors of theology, have been and still are deputed by our apostolic letters as inquisitors of heretical pravity, the former in the aforesaid parts of upper Germany, including the provinces, cities, territories, dioceses, and other places as above, and the latter throughout certain parts of the course of the Rhine; nevertheless certain of the clergy and of the laity of those parts, seeking to be wise above what is fitting, because in the said letter of deputation the aforesaid provinces, cities, dioceses, territories, and other places, and the persons and offences in question were not individually and specifically named, do not blush obstinately to assert that these are not at all included in the said parts and that therefore it is illicit for the aforesaid inquisitors to exercise their office of inquisition in the provinces, cities, dioceses, territories, and other places aforesaid, and that they ought not to be permitted to proceed to the punishment, imprisonment, and correction of the aforesaid persons for the offences and crimes above named. Wherefore in the provinces, cities, dioceses territories, and places aforesaid such offences and crimes, not without evident damage to their souls and risk of eternal salvation, go unpunished.
We therefore, desiring, as is our duty, to remove all impediments by which in any way the said inquisitors are hindered in the exercise of their office, and to prevent the taint of heretical pravity and of other like evils from spreading their infection to the ruin of others who are innocent, the zeal of religion especially impelling us, in order that the provinces, cities, dioceses, territories, and places aforesaid in the said parts of upper Germany may not be deprived of the office of inquisition which is their due, do hereby decree, by virtue of our apostolic authority, that it shall be permitted to the said inquisitors in these regions to exercise their office of inquisition and to proceed to the correction, imprisonment, and punishment of the aforesaid persons for their said offences and crimes, in all respects and altogether precisely as if the provinces, cities, territories, places, persons, and offences aforesaid were expressly named in the said letter. And, for the greater sureness, extending the said letter and deputation to the provinces, cities, dioceses, territories, places, persons, and crimes aforesaid, we grant to the said inquisitors that they or either of them joining with them our beloved son Johannes Gremper, cleric of the diocese of Coonstance, master of arts, their present notary, or any other notary public who by them or by either of them shall have been temporarily delegated in the provinces, cities, dioceses, territories, and places aforesaid, may exercise against all persons, of whatsoever condition and rank, the said office of inquisition, correcting, imprisoning, punishing and chastising, according to their deserts, those persons whom they shall find guilty as aforesaid.
And they shall also have full and entire liberty to propound and preach to the faithful word of God, as often as it shall seem to them fitting and proper, in each and all of the parosh churches in the said provinces, and to do all things necessary and suitable under the aforesaid circumstances, and likewise freely and fully to carry them out.
