On the other side of the widening rift, Eastern Orthodox were considered by western theologians to be "Schismatics". Relations between East and West were further estranged by the tragic events of the Massacre of the Latins in 1182 and Sack of Constantinople in 1204. Those bloody events were followed by several failed attempts to reach reconciliation (see: Second Council of Lyon, Council of Florence, Union of Brest, Union of Uzhhorod). During the late medieval and early modern period, terminology became much more complicated, resulting in the creation of parallel and confronting terminological systems that exist today in all of their complexity.
