Around 1300, centuries of prosperity and growth in Europe came to a halt. A series of famines and plagues, including the Great Famine of 1315–1317 and the Black Death, reduced the population to around half of what it was before the calamities. Along with depopulation came social unrest and endemic warfare. France and England experienced serious peasant uprisings, such as the Jacquerie and the Peasants' Revolt, as well as over a century of intermittent conflict in the Hundred Years' War. To add to the many problems of the period, the unity of the Catholic Church was shattered by the Western Schism. Collectively these events are sometimes called the Crisis of the Late Middle Ages.

What are the series of events that ended centuries of prosperity in Europe, starting around 1300, known as?
Answer: the Crisis of the Late Middle Ages
