In Europe, the Medieval Warm Period ended sometime towards the end of the 13th century, bringing the "Little Ice Age"[16] and harsher winters with reduced harvests. In the autumn of 1314, heavy rains began to fall, which were the start of several years of cold and wet winters.[11] The already weak harvests of the north suffered and the seven-year famine ensued. In the years 1315 to 1317 a catastrophic famine, known as the Great Famine, struck much of North West Europe. It was arguably the worst in European history, perhaps reducing the population by more than 10%.[11] Records recreated from dendrochronological studies show a hiatus in building construction during the period, as well as a deterioration in climate.[17] It has been argued that the famine came about as the result of a large population growth in the previous centuries, with the result that, in the early 14th century the population began to exceed the number that could be sustained by productive capacity of the land and farmers.[11]


Genoese (red) and Venetian (green) maritime trade routes in the Mediterranean and Black SeaIn Northern Europe, new technological innovations such as the heavy plough and the three-field system were not as effective in clearing new fields for harvest as they were in the Mediterranean because the north had poor, clay-like, soil.[11] Food shortages and rapidly inflating prices were a fact of life for as much as a century before the plague. Wheat, oats, hay and consequently livestock, were all in short supply. Their scarcity resulted in malnutrition, which increases susceptibility to infections due to weakened immunity.

do you see history repeating its self now look out for sickness and plagues as thing deteriorate , food shortages , services break down more rats , cockroaches bed bugs ect ,deppression all contributing to repeating history
