Following the expulsion of the Jews in 1349, Basel publicly resolved to not allow any Jews back into the city for at least 200 years. However, less than 15 years later, in the wake of the disastrous earthquake of 1356, Jews were allowed back and by 1365, the existence of a second Jewish community is documented. It is estimated to have numbered about 150 people (out of a total population of some 8,000) by 1370.
