Answer
The atrocities witnessed during World War II profoundly impacted Raphael Lemkin, a Polish lawyer, and scholar. Lemkin coined the term "genocide" to describe these deliberate and systematic acts aimed at the destruction of an entire national, ethnic, racial, or religious group. Lemkin's personal experiences and extensive research on the subject laid the groundwork for the development of the concept and the eventual adoption of the Genocide Convention in 1948.
