Diasporic studies emerged in the 1960s to analyze populations dispersed from their homeland. It was originally used to describe the Jewish tradition but now applies more broadly. A diaspora refers to a forced dispersion, while migration is willful. Robin Cohen identified four phases of diaspora studies: from the original Jewish prototype to increasingly challenging and reclaiming the concept to include various refugee and minority groups. Key aspects of a diaspora include collective memory of the homeland, alienation from it, hopes of eventual return, and maintaining a relationship with the homeland, as seen in biblical stories like Joseph, Job, and Daniel.
