Western culture itself was significantly influenced by the emergence of Christianity and its adoption as the state church of the Roman Empire in the late 4th century and the term "Christendom" largely indicates this intertwined history. Western Christianity was significantly influenced by Hellenistic religion (notably Platonism) as well as the Roman imperial cult. Western Christianity is based on Roman Catholicism (Latin Rite), as opposed to Eastern Orthodoxy, from which it was divided by the Great Schism of the 11th century, and further includes all Protestant traditions splitting off Roman Catholicism from the 16th century.
