Mass killings refer to incidents where a large number of people are killed in a single event or over a short period of time. These events can occur in various contexts, including wars, genocides, and terrorist attacks. The term often encompasses actions that result in the deaths of multiple individuals, typically defined as four or more victims in a single incident. Such acts can be driven by political, ideological, or social motives and may involve firearms, explosives, or other means. Notable examples include the Holocaust, the Rwandan Genocide, and various mass shootings in public spaces. Understanding the causes and consequences of mass killings is crucial for prevention and response efforts.
