Famine! You don't hear about it any more in industrial societies, but in pre-industrial periods its grim spectre was always lurking in the background. Thus, May is a balmy month in Europe, but in the middle ages it was also often the hungry month for poor peasants, as the harvest of the previous year ran out before the new one was available. Thus, it required only a poor harvest, a hard winter, or the depredations of an army for those living on the edge to be pushed over. In really bad years, most of the population would be affected, and mass starvation ensured. Ironically, at such times a plentiful supply of meat was available, but a heavy taboo lay upon it: the bodies of the dead. Initially, no doubt, the taboo was broken when starving individuals sliced off a steak from the body of someone who had already succumbed to starvation. Since no-one was actually harmed, it is difficult to hold it blameworthy. However, later the temptation would arise to deliberately hasten the death. But what happened in Egypt in 1201 was truly horrible.
