ANSWER: GENOCIDE
EXPLANATION: GENOCIDE refers to the physical destruction of a group of people (either accidentally or deliberately), due to their ethnic group, race, nationality, or religious beliefs.
However, Genocide had been since addressed in the United Nations Article 2 of the Convention on the Prevention and Punishment of the Crime of Genocide (CPPCG) held in 1948.
Example of Genocide widely known is "the Holocaust", which is used to describe the killing of about six (6) million European Jews by National Socialist German Workers Party in Germany (led by Adolf Hitler).
They defendants Sacco and Vanzetti were Italian anarchist immigrants, this showed the rise of Nativism because Nativists hate foreigners and immigrants. Also, the case received such backlash due to lack of proof yet both men were found guilty and killed.
