Anti-Protestantism originated in a reaction by militant societies connected to the Roman Catholic Church alarmed at the spread of Protestantism following the Protestant Reformation of the 16th century. Martin Luther's Proclamation occurred in 1517. By 1540, Pope Paul III had sanctioned the first society pledged to extinguish Protestantism. Christian Protestantism was denounced as heresy, and those supporting these doctrines were excommunicated as heretics. Thus by canon law and the practice and policies of the Holy Roman Empire of the time, Protestants were subject to persecution in those territories, such as Spain, Italy and the Netherlands, in which the Catholic rulers were then the dominant power. This movement was started by the reigning Pope and various political rulers with a more political stake in the controversy then a religious one. These princes instituted policies as part of the Spanish Inquisition, abuses of that crusade originally authorized for other reasons such as the Reconquista, and Morisco conversions, which ultimately led to the Counter Reformation and the edicts of the Council of Trent. Therefore, the political repercussions of various European rulers supporting Roman Catholicism for their own political reasons over the new Protestant groups, only subsequently branded as heretical after rejection by the adherents of these doctrines of the Edicts of the Council of Trent, resulted in religious wars and outbreaks of sectarian violence.

Eastern Orthodoxy had comparatively little contact with Protestantism for geographic, linguistic and historical reasons. Protestant attempts to ally with Eastern Orthodoxy proved problematic. In general, most Orthodox had the impression that Protestantism was a new heresy that arose from various previous heresies.
In 1771, Bishop Charles Walmesley published his General History of the Christian Church from her birth to her Final Triumphant States in Heaven chiefly deduced from the Apocalypse of St. John the Apostle, written under the pseudonym of Signor Pastorini. The book forecast the end of Protestantism by 1825 and was published in at least 15 editions and several languages.
By the 19th century and later, some Eastern Orthodox thinkers, such as Berdyaev, Seraphim Rose, and John Romanides believed that Northern Europe had become secular or virtually atheist due to its having been Protestant earlier. In recent eras Orthodox anti-Protestantism has grown due to aggressive Protestant proselytization in predominantly Orthodox countries.

The Protestant Reformation led to a long period of warfare and communal violence between Catholic and Protestant factions, sometimes leading to massacres and forced suppression of the alternative views by the dominant faction in much of Europe.
Anti-Protestantism originated in a reaction by the Catholic Church against the Reformation of the 16th century. Protestants were denounced as heretics and subject to persecution in those territories, such as Spain, Italy and the Netherlands in which the Catholics were the dominant power. This movement was orchestrated by popes and princes as the Counter Reformation. There were religious wars and eruptions of sectarian hatred such as the St Bartholomew's Day Massacre of 1572, part of the French Wars of Religion in some countries, though not in others.
In 1870 the newly formed Kingdom of Italy annexed the remaining Papal States, depriving the Pope of his temporal power. However, Papal rule over Italy was later restored by the Italian Fascist régime (albeit on a greatly diminished scale) in 1929 as head of the Vatican City state; under Mussolini's dictatorship, Catholicism became the State religion of Fascist Italy.
In 1938, the Italian Racial Laws and Manifesto of Race were promulgated by the Fascist régime to both outlaw and persecute Italian Jews and Protestants, especially Evangelicals and Pentecostals. Thousands of Italian Jews and a small number of Protestants died in the Nazi concentration camps.
In Franco's authoritarian Spanish State (1936–1975), Protestantism was deliberately marginalized and persecuted. During the Civil War, Franco's regime persecuted the country's 30,000 Protestants, and forced many Protestant pastors to leave the country. Once authoritarian rule was established, non-Catholic Bibles were confiscated by police and Protestant schools were closed. Although the 1945 Spanish Bill of Rights granted freedom of private worship, Protestants suffered legal discrimination and non-Catholic religious services were not permitted publicly, to the extent that they could not be in buildings which had exterior signs indicating it was a house of worship and that public activities were prohibited.
