In present and past migration processes the fate of the individual becomes tangible much faster than in many other historical processes. Hence, it is not uncommon that people take sides with the migrant and possibly also of his or her country of origin, even though the academia should refrain from biased judgements. Not least as a result of the "refugee crisis" of 2015, a noticeable need for orientation knowledge based on economics and economic history has developed, which historical migration research has not been able to satisfy so far. The aim of this first volume, as well as of the series as a whole, is therefore to overcome the corresponding gaps in research by taking innovative and provocative paths in order to stimulate discussion.
