TY - GEN A1 - Lüthi, Barbara T1 - Migration and Migration History (Version 1.0) N2 - Migration has been a constant feature of human history – "homo migrans" has existed ever since "homo sapiens". Moving away from the traditional nation-based dichotomy of emigration – immigration, the less specific term migration allows for many possible trajectories, time spans, directions and destinations. It can be temporary or long-term, voluntary or forced. It can occur in stages or in cycles, and can be mono-directional or more varied. Generally speaking, however, human migration can be defined as crossing the boundary of a political or administrative unit for a certain minimum period.
