I want to know the answer to the following question:
Along with controversy and schism, what upset the peace of the Church during the Late Middle Ages?
All the background I'm provided with is that "The Late Middle Ages was marked by difficulties and calamities including famine, plague, and war, which significantly diminished the population of Europe; between 1347 and 1350, the Black Death killed about a third of Europeans.". Is that enough to answer the question?
Answer: no
