Even if it is impossible to give an accurate numerical account of the losses due to pestilence in the course of the Thirty Years’ War, we have seen in a general way how epidemics of dysentery, typhus fever, and bubonic plague followed at the heels of armies, how they were borne from place to place, and how the devastation of the country caused by the war led to an absolute dearth of the necessaries of life, and thereby helped the pestilences to spread. We have mentioned only those places regarding which we have specific information, and they can be regarded only as examples of how these pestilences appeared; as a matter of fact, however, conditions were very much the same in all parts of the country. At the same time these examples show satisfactorily that the great depopulation of Germany during the Thirty Years’ War was chiefly caused by severe epidemics of typhus fever and bubonic plague. It will be of interest to assemble the figures (such as have been recorded) relating to the number of deaths that occurred in a few of the larger cities during the Thirty Years’ War. We include Basel among those cities, since, being situated close to the border of that part of Germany where the war was carried on during two rather long periods, it was necessarily attacked by the prevalent pestilences. At the same time Basel affords an example of how quickly these pestilences disappeared from the cities, even in the seventeenth century, if external conditions permitted the authorities to take the necessary measures of prevention and precaution, and if the cities were not constantly being reinfected. We give the total number of deaths, and merely remark that the population in all German cities in the course of the Thirty Years’ War decreased considerably. In the case of Leipzig, Dresden, and Frankfurt-on-the-Main the still-births are included, but not in the case of Augsburg, Basel, and Strassburg. As a rule the country-people who fled to the cities are not included among the dead; only in the case of Strassburg, and perhaps also in that of Breslau for the year 1633, are they included.
