DIASPORA means:

The term DIASPORA (in Greek, διασπορά – "a scattering or sowing of seeds") refers to:

The forced or voluntary dispersal of any population sharing common ethnic identity to leave their settled territory, and become residents in areas often far removed from the former. Diaspora cultural development often assumes a different course to the population in the original place of settlement, and tends to vary between remotely separated communities in culture, traditions and other factors. The last vestige of cultural affiliation in Diaspora is usually found community resistance to language change*.
