Pogrom

“Pogrom” refers to general violence against an ethnic or religious group of people – often Jewish – usually in an effort to persuade them to leave an area.

Whereas genocide is systematic killing, pogrom seems to refer more generally to violent harassment. It can sometimes culminate in killings or even larger-scale massacres, but they would need to be less sporadic and more systemic, sustained, and organized to be classified as “genocide.”

(To be clear, the definitions are highly subjective and emotionally charged. I’m not sure anyone agrees beyond the basics.)

“Pogrom” is a Russian word for “devastation” or “destruction.” It was first used in its current context during the anti-Jewish riots and violence in Russian during the late 19th century.
