Abstract
In A.D. 1346 some 100 million people inhabited Europe, northern Africa and the Near East. Five years later 25 million were dead--victims of the Black Death. The plague kept reappearing, but the epidemics did not spread as widely: apparently a new and milder strain of Yersinia pestis evolved that made at least some people immune to the virulent strain.Entities:
