Final answer:
Diaspora means the dispersal of large ethnic groups from their homelands, often due to conflict or search for opportunities, leading to populations with strong ties to their origin country.
Step-by-step explanation:
The term diaspora refers to the movement and dispersal of large ethnic groups from their homelands typically because of warfare, institutionalized violence, or seeking opportunities such as education or employment. This results in the creation of a population united by ties to a homeland where they no longer live, often retaining a collective memory and identity connected to their country of origin. Native American groups experienced such a diaspora when they were displaced and forcibly removed from their ancestral lands, which has led to significant cultural and economic consequences.
