Final answer:
The term for efforts by one ethnic or religious group to eliminate another in a given area is called genocide, which can involve actions like systematic killing and forced displacement.
Step-by-step explanation:
Efforts by representatives of one ethnic or religious group to remove or destroy another group of people in a given area represent what we call genocide. This term encompasses a range of actions, including the systematic killing of people, forced displacement, and other acts intended to destroy the existence of a specific ethnic or religious group. Genocide can also involve dehumanization, polarization, and persecution, which are steps that lead to the escalation of violence against the targeted group. History has seen numerous instances of genocide, such as during the Holocaust and more recently in the Darfur region of Sudan. Prevention and intervention are critical in addressing the underlying issues and halting the progression towards such atrocities.
