What were the consequences of religious schism?

A religious schism is a division between people who considered themselves to be of one faith before the schism itself. There have been multiple religious schisms in history, each with their own specific consequences. Examples of such schisms in Christianity include the schism of Eastern orthodoxy from Western catholicism (which is usually dated at around 1054) or the Great schism in the Western papacy from 1378 to 1417.
