We sacked Constantinople and later Pope John Paul II publicly apologized to the Orthodox.Continue
First, the Christian nations of Europe were definitely not the aggressors. The Moslems had been aggressors against the Christians since the seventh century. Their attacks on Christian countries were still going on in the eleventh century. In 1071 the Turks had attacked and virtually annihilated the Byzantine army at Manzikert. It was this defeat that led the Byzantine Emperor to appeal to the Pope for aid against the Moslems. The Christian countries of Europe were clearly justified in defending themselves against Moslem attacks and also in going on the offensive in order to prevent future attacks. At no point did the Crusaders attack the Moslem homeland, Arabia, but only those originally Christian territories that the Moslems had conquered.
Second, it certainly was and is appropriate for Christians to defend themselves and the innocent and helpless against attacks, which is exactly what the Crusaders were doing. It is also appropriate for Christians to try to regain lands which their enemy had conquered, as was the case with the Holy Land. The religious significance of the Holy land makes it even better that Christians try to regain it rather than worse, since Christians had every right to govern the lands where Christ had walked and to protect them from desecration.
Finally, there were certainly abuses during the Crusades, most notably the Sack of Jerusalem and the Sack of Constantinople, both of which are discussed below. But an immoral action during a war does not detract from the justice of the cause of the war. The immoral action should be condemned, as Godfrey de Bouillon condemned the Sack of Jerusalem and Simon de Montfort condemned the Sack of Constantinople, but the war itself remains just.
Basically, Pope John Paul II took the high road and bit his tongue.
Because the Orthodox did horrible things to Catholics prompting the sacking.
Am I right? Im not an actual historian, but i feel i read enough books to get a birds eye view of that time period.
