Genocide.

In general terms, the word "genocide" is used to refer to instances in which one group or nation sets about systematically exterminating a specific ethnic, racial, national, or religious population. It is undoubtedly true that such killings have happened all throughout history, but genocide as a term did not come into existence until near the end of World War II (1939–45). The horrors of the Holocaust, the Nazi German campaign of extermination of Jews, Roma, LGBTQ+ people, individuals with disabilities, and a wide variety of others, led scholars and commentators to seek a new language to describe what had occurred. Raphael Lemkin, a lawyer of Polish-Jewish descent, coined the term "genocide" to describe the Nazi atrocities. Genocide combines the prefix geno-, from the Greek term for race or tribe, with the suffix -cide, from the Latin term for killing.
