Haunted Europe? The Catholic Church was keeping Islam and Judaism at bay. You’re so ignorant. The church was dealing with the JQ and Zionism looooong before it was hip.

The Catholic Church was started by Jesus. Look it up.

Forced conversions are against the faith, whoever may have done it:

1885 A.D. - Pope Leo XIII - “[No] one should accuse the Church of being wanting in gentleness of action or largeness of view, or of being opposed to real and lawful liberty. ... [R]ulers [may], for the sake of securing some great good or of hindering some great evil, allow...each kind of religion [to have] its place in the State. And, in fact, the Church is wont to take earnest heed that no one shall be forced to embrace the Catholic faith against his will, for, as St. Augustine wisely reminds us, ‘Man cannot believe otherwise than of his own will.’ ” (Immortale Dei 36)

1876 A.D. - Archbishop Gibbons - “A man enjoys religious liberty when he possesses the free right of worshiping God according to the dictates of a right conscience, and of practicing a form of religion most in accordance with his duties to God. Every act infringing on his freedom of conscience is justly styled religious intolerance. This religious liberty is the true right of every man because it corresponds with a most certain duty which God has put upon him. … [The] Catholic Church has always been the zealous promoter of religious and civil liberty… [W]henever any encroachments on these sacred privileges of man were perpetrated by professing members of the Catholic faith, these wrongs, far from being sanctioned by the Church, were committed in palpable violation of her authority. … Her doctrine is, that as man by his own free will fell from grace, so of his own free will must he return to grace. Conversion and coercion are two terms that can never be reconciled.” (Faith of Our Fathers Chapter 17)

1608 A.D. - Robert Persons - “[Consider] the grievous sin which they commit, who force, and press other men to swear against their consciences, then which, almost nothing can be imagined more heinous: for it is to thrust men headlong (especially such as are fearful) into the very precipitation and downfall of hell itself. ... For he that [would] force a Jew, or Turk to swear, that there [is] a blessed Trinity, either knowing or suspecting that they would do it against their Conscience, [would] sin grievously, by forcing them to commit that sin. This is Catholic doctrine, which I also think the learned Protestants themselves will not deny.” (The Judgment of a Catholic Englishman Living in Banishment for his Religion Section 1 Paragraph 35)

1528 A.D. - St. Thomas More - “The fear of [the] outrages and mischiefs [which] follow upon [non-Catholic] sects and heresies, with the proof that men have had in some countries thereof, have been the cause that princes and people have been constrained to punish heresies by terrible death, whereas else more easy ways had been taken with them.” (Dialogue Concerning Heresies, Part IV, Chapter 13)

And: “[The princes] never indeed [would have] fallen so sore to force and violence against heretics, [unless] the violent cruelty first used by the heretics themself against good catholic folk, [drove] good princes thereto.” (Dialogue Concerning Heresies, Part IV, Chapter 13)

And: “[As] I said before, if the heretics had never begun with violence, though they had used all the ways they could to [attract] the people by preaching...yet if they had set violence aside, good Christian people [would have perhaps] yet unto this day used less violence toward them than they do now.” (Dialogue Concerning Heresies, Part IV, Chapter 13)

1274 A.D. - St. Thomas Aquinas - “[T]he heathens and the Jews...are by no means to be compelled to the faith, in order that they may believe, because to believe depends on the [free] will.” (Summa Theologica II-II Question 10 Article 8)

And: “Christ's faithful...wage war with unbelievers, not indeed for the purpose of forcing them to believe, because even if they were to conquer them, and take them prisoners, they should still leave them free to believe, if they will.” (Summa Theologica II-II Question 10 Article 8)

And: “Human government is derived from the Divine government, and should imitate it. Now although God is all-powerful and supremely good, nevertheless He allows certain evils to take place in the universe, which He might prevent, lest, without them, greater goods might be forfeited, or greater evils ensue.” [[Note: in classic Catholic theology, God doesn't prevent all evil because doing so would take away a greater good, that being man's free will.]] “Accordingly in human government also, those who are in authority, rightly tolerate certain evils, lest certain goods be lost, or certain greater evils be incurred.” (Summa Theologica II-II Question 10 Article 11)

And: “[The] rites of [some] unbelievers...[may] be tolerated...in order to avoid an evil, e.g. the scandal or disturbance that might ensue, or some hindrance to the salvation of those who if they were unmolested might gradually be converted to the faith. For this reason the Church, at times, has tolerated the rites even of heretics and pagans...” (Summa Theologica II-II Question 10 Article 11)

1201 A.D. - Pope Innocent III - “It is contrary to the Christian religion to force others to into accepting and practicing Christianity if they are always unwilling and totally opposed.” “The one who never consents and is absolutely unwilling receives neither the reality [rem] nor the character [characterem] of the sacrament because express dissent is something more than not consenting at all.” (Letter Maiores Ecclesiae causas to Archbishop Humbert of Arles)

~1150 A.D. - Gratian's Decree - "Those who sincerely wish to lead people who stand outside the Christian religion into the proper faith should strive to do so by gentle means rather than by harsh means, lest adversity alienate the mind of those whom a reasonable argument would have been able to attract. For those who do otherwise and wish to force them, under such pretext, from the customary observance of their rite are seen clearly to attend to their own affairs more intently than those of God." (Distinction 45 Causa 3, quoting Pope St. Gregory I, as quoted in Dwayne Carpenter, Alfonso X and the Jews: An Edition of and Commentary on Siete Partidas 7.24 "De Los Judíos", Volume 115, [Berkeley, CA: University of California Press, 1986], 80.)

1065 A.D. - Pope Alexander II said: “Although We have no doubt it stems from the zeal of devotion that your Nobility arranges to lead Jews to the worship of Christendom...you seem to do it with a zeal that is inordinate. For we do not read that our Lord Jesus Christ violently forced anyone into his service, but that by humble exhortation, leaving to each person his own freedom of choice, he recalled from error whomsoever he had predestined to eternal life, doing so not by judging them, but by shedding his own blood. Likewise, the blessed Gregory forbids, in one of his letters, that the said people should be drawn to the faith by violence.” (Letter Licet ex to Prince Landolfo of Benevento)

866 A.D. - Pope Nicholas I said: “Concerning those who refuse to receive the good of Christianity and sacrifice and bend their knees to idols, we can write nothing else to you than that you move them towards the right faith by warnings, exhortations, and reason rather than by force, proving that what they know in vain, is wrong. ... Furthermore, violence is never in any way to be inflicted upon them to make them believe. For whatever is not from an inner desire [ex voto], cannot be good.” (Ad consulta vestra, Response of Nicholas I to the Bulgarians)

633 A.D. - The Fourth Council of Toledo decrees against religious intolerance: "No one should henceforth be forced to believe, [for] God hath mercy on whom he will and whom he will he hardeneth; such men should not be saved unwillingly but willingly, in order that the procedure of justice should be complete; for just as man perished obedient to the serpent out of his own free will, so will any man be saved—when called by the divine grace—by believing and in converting his own mind. They should be persuaded to convert, therefore, of their own free choice, rather than forced by violence." (Fourth Council of Toledo, Canon 57)

602 A.D. - Pope St. Gregory the Great - "Those who sincerely wish to lead people who stand outside the Christian religion into the proper faith should strive to do so by gentle means rather than by harsh means, lest adversity alienate the mind of those whom a reasonable argument would have been able to attract. For those who do otherwise and wish to force them, under such pretext, from the customary observance of their rite are seen clearly to attend to their own affairs more intently than those of God." (Letter to the Bishop of Naples as quoted in Dwayne Carpenter, Alfonso X and the Jews: An Edition of and Commentary on Siete Partidas 7.24 "De Los Judíos", Volume 115, [Berkeley, CA: University of California Press, 1986], 80.)

308 A.D. - Lactantius - “Religion, being a matter of the will, cannot be forced on anyone. In this matter it is better to employ words than blows. Of what use is cruelty? What has the rack to do with piety? Surely there is no connection between truth and violence, between justice and cruelty.” (De Divinis Institutionibus 5, 10)

And more on “forced conversions”

In the Papal states it was customary to baptize any orphan Jew or gentile child. The Jews see this as a forced conversion especially since in their traditions conversion to Christianity is to be cut off from the Jewish people whether or not their was a legal guardian for the child. the church also being the legal government would take these children as a type of "wards of the state".

the Mortara case is different and is its own can of worms. as the Child was alleged to have be baptized by emergency in secret and therefore by canon law was not a Jew and was taken from his parents. the evidence of the baptism is flimsy and I can't understand Pope Pius IX's mentality of why, he would press this issue at this time with his parents still alive. Either way the backlash in the world press and the Italian risorgimento members caused a brake down in talks with the papal states and led to the reduction the papal states to just the city of Rome.

as for a broad forced conversion no the church didn't forced any large group of Jews to convert. Military/national powers in the north of Europe, in the Americas and during the crusades did practice "forced conversions" but they were dressed up as a condition to trade, as a peace treaty or the king would foist conversion on his subjects after his personal conversion.
