The Great Schism

I interviewed a Christian who was alive during the time of the Great Schism to find out some general information out about the Great Schism. What he told me was that The term Great Schism is used to refer to two major events in the history of Christianity: the division between the Eastern (Orthodox) and Western (Roman) churches, and the period (1378 - 1417) during which the Western church had first two, and later three, lines of popes.
