Franco's Victory Parade

[GMC]

Well, much of that senseless anti-clerical violence was done by anarchists, who were the worst on the Republican side. If you read Orwell's "Homage to Catalonia" you can see the fully chaos that were the anarchists. I'm not surprised that anarchism today is basically chaos and drugs, it was always a fully ideological disaster. Orwell omits most of the atrocities they did, but  even so you can see the disaster of the anarchist government of Barcelona.

During the Spanish Civil War of 1936–1939, and especially in the early months of the conflict, individual clergymen were executed while entire religious communities were persecuted, leading to a death toll of 13 bishops, 4,172 diocesan priests and seminarians, 2,364 monks and friars and 283 nuns, for a total of 6,832 clerical victims, as part of what is referred to as Spain's Red Terror.[4]

8 - A War of Religion
It has been observed that, in some sense, most wars are "wars of religion," to the extent that nearly all contenders make an effort to sanctify their cause, one way or the other. This was certainly the case with twentieth-century revolutionary civil wars. The Russian Bolsheviks saw the Orthodox Church as a prime enemy, whereas their White opponents emphasized the restoration of traditional religion. The White militia in Finland were largely Lutheran farmers, for whom the religious difference with their enemy was fundamental. In Hungary, the transitory Bela Kun dictatorship of 1919 went farther than the Bolsheviks in religious matters and sought to nationalize the churches directly. With all these precedents, however, religion defined the Spanish conflict in ways that went beyond any other revolutionary civil war.

In recent decades, some attempt has been made to study Spanish anticlericalism and to try to understand why it took the form of unprecedented violence. Such studies often do no more than repeat the arguments of the anticlericals themselves: that the church held tyrannical public power, that it wielded great economic dominion, that priests were abusive and hypocritical. None of these arguments held much validity for 1936: church and state had been separated for five years, the Church in Spain had long since lost most of its economic resources, and whether priests were hypocrites or good Catholics should scarcely have mattered to unbelievers. The left's hatred of Catholicism was motivated by the same feelings as those of revolutionaries and anticlerical radicals in France in 1792 and throughout the century that followed: they were convinced that the Church was the cultural and spiritual bulwark of the traditional order, and that the clergy, church buildings, and their strongest supporters were both symbolic and tangible representatives of that order, even more so than the members of conservative political and economic groups. To that extent, the motivation was itself in a certain sense religious, the expression of radical rival new secular religions, or religion substitutes – Jacobin, anarchist, and Marxist-Leninist. Bruce Lincoln has termed the phenomenon "millennial antinomianism," expressing the revolutionaries' sense of complete freedom from all rules, law, or morality in the establishment of their new millenarian utopia.
