Holy Wars S01 E02 Christians vs. Christians

Martin Luther had enough of corruption, loose morals, and depravity in the church and demanded a pure church and a pure faith. The resulting Reformation of the church and the ousting of the "depraved" popes led to a war that killed half of Europe's population at the time. Christianity was more divided than ever, with Catholics, Lutherans, and the Reformed all killing each other mercilessly.
