Events By place Europe Spring – Great Famine of 1315–1317: A famine and pestilence sweeps over Europe, and exacts so frightful a toll of human life that the phenomenon is to be regarded as one of the most impressive features of the period. It covers almost the whole of Northern Europe; the current territory of Ireland, England, France, Netherlands, Germany and Poland. The adverse weather conditions, the ensuing crop failures, and the sharp rise in food prices cause an acute shortage of food that will last for two years. The famine causes millions of deaths (according to estimates, around 10 to 25% of the urban population dies).
