The relations between the Eastern Orthodox Church and the Roman Catholic Church have long been studied over the years in academia. Much focus has been placed upon the Fourth Crusade as the final act that brought the schism of 1054 into full development between the two churches. However, it was during the First Crusade that the Roman Catholic Church made its first concrete efforts to repair relations with the Eastern Orthodox Church. Yet such efforts were eventually twisted to suit the purposes of some of the crusading lords, and thus becoming arguably the largest blow to church reunification because it lead to the permanent formation of an anti-Greek attitude in Latin Europe.
