Altogether, there have been about 150 recorded cases of blood libel (not to mention thousands of rumors) that resulted in the arrest and killing of Jews throughout history, most of them in the Middle Ages. In almost every case, Jews were murdered, sometimes by a mob, sometimes following torture and a trial.
Actual Jewish practices regarding blood and sacrifice
It has been one of history's cruel ironies that the blood libel---accusations against Jews using the blood of murdered gentile children for the making of wine and matzot---became the false pretext for numerous pogroms. And due to the danger, those who live in a place where blood libels occur are halachically exempted from using red wine, lest it be seized as "evidence" against them.

The supposed torture and human sacrifice alleged in the blood libels run contrary to the teachings of Judaism. According to the Bible, God commanded Abraham in the Binding of Isaac to sacrifice his son, but ultimately provided a ram as a substitute. The Ten Commandments in the Torah forbid murder. In addition, the use of blood (human or otherwise) in cooking is prohibited by the kosher dietary laws (kashrut). Blood from slaughtered animals may not be consumed, and must be drained out of the animal and covered with earth. (Lev 17:12-13) According to the book of Leviticus, blood from sacrificed animals may only be placed on the altar of the Great Temple in Jerusalem (which no longer existed at the time of the Christian blood libels). Furthermore, consumption of human flesh would violate kashrut.
blood libel, also called blood accusation, the superstitious accusation that Jews ritually sacrifice the children of Christians at Passover to obtain blood for unleavened bread. It first emerged in medieval Europe in the 12th century and was revived sporadically in eastern and central Europe throughout the medieval and modern periods, often leading to the persecution of Jews.
The earliest versions of the accusation involved Jews crucifying Christian children at Easter/Passover because of a prophecy. There is no reference to the use of blood in unleavened matzo bread, which evolves later as a major motivation for the crime.
Though otherwise very different from the medieval myth, there are two records of ancient stories about Jewish acts of sacrifice that have been linked to the later blood libel stories of the medieval era. The first is in the writings of the Graeco-Egyptian author Apion, who claimed that Jews sacrificed Greek victims in their temple. This accusation is known from Josephus' rebuttal of it in Against Apion. Apion states that when Antiochus Epiphanes entered the temple in Jerusalem, he discovered a Greek captive who told him he was being fattened for sacrifice. Every year, Apion claimed, the Jews would sacrifice a Greek and consume his flesh, at the same time swearing eternal hatred to Greeks. Apion's claim probably repeats ideas already in circulation as similar claims are made by Posidonius and Apollonius Molon in the 1st century BC. The second story concerns the murder of a Christian boy by a group of Jewish youths. Socrates Scholasticus (fl. 5th Century) reported that some Jews in a drunken frolic bound a Christian child on a cross in mockery of the death of Christ and scourged him until he died.
Professor Israel Jacob Yuval of the Hebrew University of Jerusalem published an article in 1993 that argues that blood libel may have originated in the 12th century from Christian views of Jewish behavior during the First Crusade. Some Jews committed suicide and killed their own children rather than be subjected to forced conversions. Yuval investigated Christian reports of these events and found that they were greatly distorted with claims that if Jews could kill their own children they could also kill the children of Christians. Yuval rejects the blood libel story as a fantasy of some Christians which could not contain any elements of truth because of the precarious nature of the Jewish minority's existence in Christian Europe.
In England in 1144 Jews of Norwich were accused of ritual murder after a boy, William of Norwich, was found dead with stab wounds in the woods. William's hagiographer, Thomas of Monmouth, claimed that every year there is an international council of Jews at which they choose the country in which a child will be killed during Easter, because, he claimed, of a Jewish prophecy that states that the killing of a Christian child each year will ensure that the Jews will be restored to the Holy Land. In 1144 England was chosen, and the leaders of the Jewish community delegated the Jews of Norwich to perform the killing. They then abducted and crucified William. The legend was turned into a cult, with William acquiring the status of martyr and pilgrims bringing offerings to the local church.
This was followed by similar accusations in Gloucester (1168), Bury St Edmunds (1181) and Bristol (1183). In 1189, the Jewish deputation attending the coronation of Richard the Lionheart was attacked by the crowd. Massacres of Jews at London and York soon followed. In 1190 on March 16, 150 Jews were attacked in York and then massacred when they took refuge in the royal castle, where Clifford's Tower now stands, with some committing suicide rather than being taken by the mob. The remains of 17 bodies thrown in a well in Norwich between the 12th and 13th century (5 that were shown by DNA testing to likely be members of a single Jewish family) were very possibly killed as part of one of these pogroms.
After the death of Little Saint Hugh of Lincoln, there were a series of trials and executions of Jews. The case is mentioned by Chaucer, and thus has become well-known. The eight-year-old Hugh disappeared at Lincoln on 31 July 1255. His body was discovered on 29 August, covered with filth, in a pit or well belonging to a Jewish man named Copin or Koppin. On being promised by John of Lexington, a judge, who happened to be present, that his life should be spared, Copin is said to have confessed that the boy had been crucified by the Jews, who had assembled at Lincoln for that purpose. King Henry III, on reaching Lincoln at the beginning of October, refused to carry out the promise of John of Lexington, and had Copin executed and 91 of the Jews of Lincoln seized and sent up to London, where 18 of them were executed. The rest were pardoned at the intercession of the Franciscans (Jacobs, Jewish Ideals, pp. 192–224). Within a few decades, Jews would be expelled from all of England in 1290 and not allowed to return until 1655.
The first case outside England was in Blois in 1171. This was the site of a blood libel accusation against its Jewish community that led to 31 Jews (by some accounts 40) being burned to death. Thomas of Monmouth's story of the annual Jewish meeting to decide which local community will kill a Christian child also quickly spread to the continent. An early version appears in Bonum Universale de Apibus ii. 29, § 23, by Thomas of Cantimpré (a monastery near Cambray). Thomas wrote "It is quite certain that the Jews of every province annually decide by lot which congregation or city is to send Christian blood to the other congregations." Thomas of Cantimpré also believed that since the time when the Jews called out to Pontius Pilate, "His blood be on us, and on our children" (Matthew 27:25), they have been afflicted with hemorrhages:
A very learned Jew, who in our day has been converted to the (Christian) faith, informs us that one enjoying the reputation of a prophet among them, toward the close of his life, made the following prediction: 'Be assured that relief from this secret ailment, to which you are exposed, can only be obtained through Christian blood ("solo sanguine Christiano").' This suggestion was followed by the ever-blind and impious Jews, who instituted the custom of annually shedding Christian blood in every province, in order that they might recover from their malady.
Thomas added that the Jews had misunderstood the words of their prophet, who by his expression "solo sanguine Christiano" had meant not the blood of any Christian, but that of Jesus—the only true remedy for all physical and spiritual suffering. Thomas did not mention the name of the "very learned" proselyte, but it may have been Nicholas Donin of La Rochelle, who in 1240 had a disputation on the Talmud with Yechiel of Paris, and who in 1242 caused the burning of numerous Talmudic manuscripts in Paris. It is known that Thomas was personally acquainted with this Nicholas.
Painting of Werner of Oberwesel as a martyr
At Pforzheim, Baden, the corpse of a seven-year-old girl was found in the river by fishermen. The Jews were suspected, and when they were led to the corpse, blood allegedly began to flow from the wounds; led to it a second time, the face of the child became flushed, and both arms were raised. In addition to these miracles, there was the testimony of the daughter of the wicked woman who had sold the child to the Jews. A regular judicial examination did not take place; it is probable that the above-mentioned "wicked woman" was the murderess. That a judicial murder was then and there committed against the Jews in consequence of the accusation is evident from the manner in which the Nuremberg "Memorbuch" and the synagogal poems refer to the incident (Siegmund Salfeld, Das Martyrologium des Nürnberger Memorbuches (1898), pp. 15, 128-130). At Weissenburg, a miracle alone decided the charge against the Jews. According to the accusation, the Jews had suspended a child (whose body was found in the Lauter river) by the feet, and had opened every artery in his body to obtain all the blood. Again, supernatural claims were made: the child's wounds were said to have bled for five days afterward, despite its treatment.
At Oberwesel, "miracles" again constituted the only evidence against the Jews. The corpse of the 11-year-old Werner of Oberwesel was said to have floated up the Rhine (against the current) as far as Bacharach, emitting radiance, and being invested with healing powers. In consequence, the Jews of Oberwesel and many other adjacent localities were severely persecuted during the years 1286-89. Emperor Rudolph I, to whom the Jews had appealed for protection, issued a public proclamation to the effect that great wrong had been done to the Jews, and that the corpse of Werner was to be burned and the ashes scattered to the winds. The statement was made, in the "Chronicle" of Konrad Justinger of 1423, that at Bern in 1294 the Jews tortured and murdered a boy called Rudolph. The historical impossibility of this widely credited story was demonstrated by Jakob Stammler, pastor of Bern, in 1888. It has been speculated whether the Kindlifresserbrunnen ("Child Eater Fountain") in Bern might refer to the alleged ritual murder of 1294.
Renaissance and Baroque
From an 18th-century etching from Brückenturm. Above: The murdered body of Simon of Trent. Below: The "Judensau."
Simon of Trent, aged two, disappeared, and his father alleged that he had been kidnapped and murdered by the local Jewish community. Fifteen local Jews were sentenced to death and burned. Simon was regarded as a saint, and was canonized by Pope Sixtus V in 1588. His status as a saint was removed in 1965 by Pope Paul VI, though his murder is still promoted as a fact by a handful of extremists.
Christopher of Toledo, also known as Christopher of La Guardia or "the Holy Child of La Guardia," was a four-year-old Christian boy supposedly murdered by two Jews and three Conversos (converts to Christianity). In total, eight men were executed. It is now believed that this case was constructed by the Spanish Inquisition to facilitate the expulsion of Jews from Spain. He was canonized by Pope Pius VII in 1805. Christopher has since been removed from the canon, though once again, a handful of individuals still claim the validity of this case.
In a case at Tyrnau (Nagyszombat, today Trnava, Slovakia), the absurdity, even the impossibility, of the statements forced by torture from women and children shows that the accused preferred death as a means of escape from the torture, and admitted everything that was asked of them. They even said that Jewish men menstruated, and that the latter therefore practiced the drinking of Christian blood as a remedy.
At Bösing (Bazin, today Pezinok, Slovakia), it was charged that a nine-year-old boy had been bled to death, suffering cruel torture; thirty Jews confessed to the crime and were publicly burned. The true facts of the case were disclosed later, when the child was found alive in Vienna. He had been taken there by the accuser, Count Wolf of Bazin, as a means of ridding himself of his Jewish creditors at Bazin.
At Rinn, near Innsbruck, a boy named Andreas Oxner (also known as Anderl von Rinn) was said to have been bought by Jewish merchants and cruelly murdered by them in a forest near the city, his blood being carefully collected in vessels. The accusation of drawing off the blood (without murder) was not made until the beginning of the 17th century, when the cult was founded. The older inscription in the church of Rinn, dating from 1575, is distorted by fabulous embellishments—for example, that the money paid for the boy to his godfather turned into leaves, and that a lily blossomed upon his grave. The cult continued until officially prohibited in 1994 by the Bishop of Innsbruck.
The only child-saint in the Russian Orthodox Church is the six-year-old boy Gavriil Belostoksky from the village Zverki. According to the legend supported by the church, the boy was kidnapped from his home during the holiday of Passover while his parents were away. Shutko, who was a Jew from Białystok, was accused of bringing the boy to Białystok, poking him with sharp objects and draining his blood for nine days, then bringing the body back to Zverki and dumping it at a local field. A cult developed, and the boy was canonized in 1820. His relics are still the object of pilgrimage. On All Saints Day, July 27, 1997, the Belorussian state TV showed a film alleging the story is true. The revival of the cult in Belarus was cited as a dangerous expression of antisemitism in international reports on human rights and religious freedoms which were passed to the UNHCR.
1823-1835 Velizh blood libel: After a Christian child was found murdered outside of this small Russian town in 1823, accusations by a drunk prostitute led to the imprisonment of many local Jews. Some were not released until 1835.
1840 Damascus affair: In February, at Damascus, a Catholic monk named Father Thomas and his servant disappeared. The accusation of ritual murder was brought against members of the Jewish community of Damascus.
1840 Rhodes blood libel: The Jews of Rhodes, under the Ottoman Empire, were accused of murdering a Greek Christian boy. The libel was supported by the local governor and the European consuls posted to Rhodes. Several Jews were arrested and tortured, and the entire Jewish quarter was blockaded for twelve days. An investigation carried out by the central Ottoman government found the Jews to be innocent.
In March 1879, ten Jewish men from a mountain village were brought to Kutaisi, Georgia to stand trial for the alleged kidnapping and murder of a Christian girl. The case attracted a great deal of attention in Russia (of which Georgia was then a part): "While periodicals as diverse in tendency as Herald of Europe and Saint Petersburg Notices expressed their amazement that medieval prejudice should have found a place in the modern judiciary of a civilized state, New Times hinted darkly of strange Jewish sects with unknown practices." The trial ended in acquittal, and the orientalist Daniel Chwolson published a refutation of the blood libel.
1882 Tiszaeszlár blood libel: The Jews of the village Tiszaeszlár, Hungary were accused of the ritual murder of a fourteen-year-old Christian girl, Eszter Solymosi. The case was one of the main causes of the rise of antisemitism in the country. The accused persons were eventually acquitted.
In 1899 Hilsner Affair: Leopold Hilsner, a Jewish vagabond, was accused of murdering a nineteen-year-old Christian woman, Anežka Hrůzová, with a slash to the throat. Despite the absurdity of the charge and the relatively progressive nature of society in Austria-Hungary, Hilsner was convicted and sentenced to death. He was later convicted of an additional unsolved murder, also involving a Christian woman. In 1901, the sentence was commuted to life imprisonment. Tomáš Masaryk, a prominent Austro-Czech philosophy professor and future president of Czechoslovakia, spearheaded Hilsner's defense. He was later blamed by Czech media because of this. In March 1918, Hilsner was pardoned by Austrian emperor Charles I. He was never exonerated, and the true guilty parties were never found.
The 1903 Kishinev pogrom, an anti-Jewish revolt, started when an anti-Semitic newspaper wrote that a Christian Russian boy, Mikhail Rybachenko, was found murdered in the town of Dubossary, alleging that the Jews killed him in order to use the blood in preparation of matzo. Around 49 Jews were killed and hundreds were wounded, with over 700 houses being looted and destroyed.
In the 1910 Shiraz blood libel, the Jews of Shiraz, Iran, were falsely accused of murdering a Muslim girl. The entire Jewish quarter was pillaged; the pogrom left 12 Jews dead and about 50 injured.
Antisemitic flier in Kiev, 1915: "Christians, take care of your children!!! It will be Jewish Passover on March 17."
In Kiev, a Jewish factory manager, Menahem Mendel Beilis, was accused of murdering a Christian child and using his blood in matzos. He was acquitted by an all-Christian jury after a sensational trial in 1913.
Jews were frequently accused of ritual murder of Christians for their blood in Der Stürmer, an antisemitic newspaper published in Nazi Germany. The infamous May 1934 issue of the paper was later banned by the Nazi authorities, because it went as far as comparing alleged Jewish ritual murder with the Christian communion.
In 2003 a private Syrian film company created a 29-part television series Ash-Shatat ("The Diaspora"). This series originally aired in Lebanon in late 2003 and was broadcast by Al-Manar, a satellite television network owned by Hezbollah. This TV series, based on the antisemitic forgery The Protocols of the Learned Elders of Zion, shows the Jewish people as engaging in a conspiracy to rule the world, and presents Jews as people who murder the children of Christians, drain their blood and use this blood to bake matzah.
In early January 2005, some 20 members of the RussianState Duma publicly made a blood libel against the Jewish people. They approached the Prosecutor General’s Office and demanded that Russia "ban all Jewish organizations.” They accused all Jewish groups of being extremists and of being “anti-Christian and inhumane, which practices extend even to ritual murders.” Alluding to previous antisemitic Russian court decrees that accused the Jews of ritual murder, they wrote that “Many facts of such religious extremism were proven in courts.” The accusation included traditional antisemitic canards, such as “the whole democratic world today is under the financial and political control of international Jewry. And we do not want our Russia to be among such unfree countries”. This demand was published as an open letter to the prosecutor general, in Rus Pravoslavnaya (Russian: Русь православная, "Orthodox Russia"), a national-conservative newspaper. This group consisted of members of the ultra-nationalist Liberal Democrats, the Communist faction, and the nationalist Motherland party, with some 500 supporters. Тhe mentioned document is known as "The Letter of Five Hundred" ("Письмо пятисот"). Their supporters included editors of nationalist newspapers as well as journalists. By the end of the month this group had received stiff criticism, and retracted its demand.

At the end of April 2005, five boys, ages 9 to 12, in Krasnoyarsk (Russia) disappeared. In May 2005, their burnt bodies were found in the city sewage. The crime was not disclosed, and in August 2007 the investigation was extended until November 18, 2007. Some Russian nationalist groups claimed that the children were murdered by a Jewish sect with a ritual purpose. Nationalist M. Nazarov, one of the authors of "The Letter of Five Hundred" alleges "the existence of a 'Hasidic sect', whose members kill children before Passover to collect their blood," using the Beilis case mentioned above as evidence. M.Nazarov also alleges that "the ritual murder requires throwing the body away rather than its concealing". "The Union of the Russian People" demanded officials thoroughly investigate the Jews, not stopping at the search in synagogues, Matzah bakeries and their offices.
During a speech in 2007, Raed Salah, the leader of the northern branch of the Islamic Movement in Israel, accused Jews of using children's blood to bake bread. "We have never allowed ourselves to knead [the dough for] the bread that breaks the fast in the holy month of Ramadan with children's blood," he said. "Whoever wants a more thorough explanation, let him ask what used to happen to some children in Europe, whose blood was mixed in with the dough of the [Jewish] holy bread." 
In 2008, a Polish team of anthropologists and sociologists investigated the currency of the blood libel myth in Sandomierz where a painting depicting the blood libel adorns the Cathedral, and discovered that these beliefs persist among Catholic and Orthodox Christians of all social classes.
In an address that aired on Al-Aqsa TV, a Hamas run TV station in Gaza, on March 31, 2010, Salah Eldeen Sultan (Arabic: صلاح الدين سلطان), founder of the American Center for Islamic Research in Columbus, Ohio, the Islamic American University in Southfield, Michigan, and the Sultan Publishing Co. and described in 2005 as "one of America's most noted Muslim scholars," alleged that Jews kidnap Christians and others in order to slaughter them and use their blood for making matzos. Sultan, who is currently a lecturer of Muslim jurisprudence at the Cairo University stated that: "The Zionists kidnap several non-Muslims [sic] – Christians and others... this happened in a Jewish neighborhood in Damascus. They killed the French doctor, Toma, who used to treat the Jews and others for free, in order to spread Christianity. Even though he was their friend and they benefited from him the most, they took him on one of these holidays and slaughtered him, along with the nurse. Then they kneaded the matzos with the blood of Dr. Toma and his nurse. They do this every year. The world must know these facts about the Zionist entity and its terrible corrupt creed. The world should know this." (Translation by the Middle East Media Research Institute)
During interview which aired on Rotana Khalijiya TV on August 13, 2012, Saudi Cleric Salman Al-Odeh stated (as translated by MEMRI) that "It is well known that the Jews celebrate several holidays, one of which is the Passover, or the Matzos Holiday. I read once about a doctor who was working in a laboratory. This doctor lived with a Jewish family. One day, they said to him: 'We want blood. Get us some human blood.' He was confused. He didn't know what this was all about. Of course, he couldn't betray his work ethics in such a way, but he began inquiring, and he found that they were making matzos with human blood." Al-Odeh also stated that "[Jews] eat it, believing that this brings them close to their false god, Yahweh" and that "They would lure a child in order to sacrifice him in the religious rite that they perform during that holiday."
In April 2013, the Palestinian non-profit organization MIFTAH, founded by Hanan Ashrawi apologized for publishing an article which criticized US President Barack Obama for holding a Passover Seder in the White House saying "Does Obama in fact know the relationship, for example, between ‘Passover’ and ‘Christian blood’..?! Or ‘Passover’ and ‘Jewish blood rituals?!’ Much of the chatter and gossip about historical Jewish blood rituals in Europe are real and not fake as they claim; the Jews used the blood of Christians in the Jewish Passover." MIFTAH's apology expressed its "sincerest regret."
In an interview which aired Al-Hafez TV on May 12, 2013, Khaled Al-Zaafrani of the Egyptian Justice and Progress Party, stated (as translated by MEMRI): "It's well known that during the Passover, they [the Jews] make matzos called the "Blood of Zion." They take a Christian child, slit his throat and slaughter him. Then they take his blood and make their [matzos]. This is a very important rite for the Jews, which they never forgo...They slice it and fight over who gets to eat Christian blood." In the same interview, Al-Zaafrani stated that "The French kings and the Russian czars discovered this in the Jewish quarters. All the massacring of Jews that occurred in those countries were because they discovered that the Jews had kidnapped and slaughtered children, in order to make the Passover matzos."
In an interview which aired on the Al-Quds TV channel on July 28, 2014 (as translated by MEMRI), Osama Hamdan, the top representative of Hamas in Lebanon, stated that "we all remember how the Jews used to slaughter Christians, in order to mix their blood in their holy matzos. This is not a figment of imagination or something taken from a film. It is a fact, acknowledged by their own books and by historical evidence." In a subsequent interview CNN's Wolf Blitzer, Hamdan defended his comments, stating that he "has Jewish friends."
In a sermon broadcast on the official Jordanian TV channel on August 22, 2014, Sheik Bassam Ammoush, a former Minister of Administrative Development who was appointed Jordan's House of Senate ("Majlis al-Aayan") in 2011, stated (as translated by MEMRI): "In [the Gaza Strip] we are dealing with the enemies of Allah, who believe that the matzos that they bake on their holidays must be kneaded with blood. When the Jews were in the diaspora, they would murder children in England, in Europe, and in America. They would slaughter them and use their blood to make their matzos...They believe that they are God's chosen people. They believe that the killing of any human being is a form of worship and a means to draw near their god."
Views of the Catholic Church
The attitude of the Roman Catholic Church towards these accusations and the cults venerating children supposedly killed by Jews has varied over time. The papacy generally opposed them, although it had problems in enforcing its opposition.
In 1911, the Dictionnaire apologétique de la foi catholique, an important French Catholic encyclopedia, published an analysis of the blood libel accusations. This may be taken as being broadly representative of educated Catholic opinion in continental Europe at that time. The article noted that the popes had generally refrained from endorsing the blood libel, and it concluded that the accusations were unproven in a general sense, but it left open the possibility that some Jews had committed ritual murders of Christians. Other contemporary Catholic sources (notably the Jesuit periodical Civiltà cattolica) promoted the blood libel as truth.
Today, the accusations are almost entirely discredited in Catholic circles, and the cults associated with them have fallen into disfavour. For example, Simon of Trent was deleted from the Calendar of Saints in 1965 and does not appear in the current (2000) edition of the Roman Martyrology.
Pope Innocent IV took action against the blood libel: "5 July 1247 "Mandate to the prelates of Germany and France to annul all measures adopted against the Jews on account of the ritual murder libel, and to prevent accusation of Arabs on similar charges" (The Apostolic See and the Jews, Documents: 492-1404; Simonsohn, Shlomo, p. 188-189,193-195,208). In 1247 he wrote also that "Certain of the clergy, and princes, nobles and great lords of your cities and dioceses have falsely devised certain godless plans against the Jews, unjustly depriving them by force of their property, and appropriating it themselves;...they falsely charge them with dividing up among themselves on the Passover the heart of a murdered boy...In their malice, they ascribe every murder, wherever it chance to occur, to the Jews. And on the ground of these and other fabrications, they are filled with rage against them, rob them of their possessions without any formal accusation, without confession, and without legal trial and conviction, contrary to the privileges granted to them by the Apostolic See...Since it is our pleasure that they shall not be disturbed,...we ordain that ye behave towards them in a friendly and kind manner. Whenever any unjust attacks upon them come under your notice, redress their injuries, and do not suffer them to be visited in the future by similar tribulations" (Catholic Encyclopedia (1910), Vol. 8, pp. 393–394). 
Pope Gregory X (1271–1276) issued a letter which criticized the practice of blood libels and forbade arrests and persecution of Jews based on a blood libel, ...unless which we do not believe they be caught in the commission of the crime. .
Pope Paul III, in a bull of 12 May 1540, made clear his displeasure at having learned, through the complaints of the Jews of Hungary, Bohemia and Poland, that their enemies, looking for a pretext to lay their hands on the Jews' property, were falsely attributing terrible crimes to them, in particular that of killing children and drinking their blood.
St. Pius V in the bull Hebraeorum gens (26 February 1569) did not reference blood libel, but he did make multiple accusations against the Jews, including: usury, theft, receiving stolen goods, pimping, divination and magic. He finishes with this accusation: "Finally, we have sufficiently investigated and explored how unworthily this perverse race attacks the name of Christ; how much hated it is by all those who bear that name; and, finally, with what cunning it plots against their lives."
Pope Benedict XIV wrote a bull Beatus Andreas (22 February 1755) in which he does not express any doubt concerning the murders of children ascribed to the Jews. He states they are perpetrated "out of hatred of Christ" and "out of hatred for the Christian faith" in his De servorum Dei beatificatione. In the bull he speaks about determining what is to be done "when there arises a case of this sort, which often comes to be put forward, concerning some boy who was slain by the Hebrews in Holy Week out of hostility to Christ, such as Blessed Simon and Anderl and also many of the other murdered boys whom the authors mention".
In 2003, the Egyptian newspaper Al-Ahram published a series of articles by Osama Al-Baz, a senior advisor to then Egyptian President Hosni Mubarak. Among other things, Osam Al-Baz explained the origins of the blood libel against the Jews. He said that Arabs and Muslims have never been antisemitic, as a group, but accepted that a few Arab writers and media figures attack Jews "on the basis of the racist fallacies and myths that originated in Europe". He urged people not to succumb to "myths" such as the blood libel.
