Two front crusading struggle, which have no relation to the original idea of ??an armed pilgrimage, formed in the first third of the XIII century. One of them mentioned earlier - it was the result of the Fourth Crusade and covered part of the Balkan Peninsula and the west of Asia Minor. Here Catholic soldiers fought against the "schismatic" (Orthodox), that is, the same Christians, K; Ik themselves, but do not obey the apostolic Roman throne. The war was waged with varying success and demanded constant replenishment of military koptingentov, especially after the defeat of the Crusaders iodine Adrianople in 1205. I must say that this is the southern direction until the end of the era of cross distract the most of the crusader forces, including because of the potential "champions of faith" preferred to go to fight in close Greece than is far Levant.
