Organized attacks on Jews have historically been called POGROMS. Pogroms differ from events like the Holocaust in that pogroms were (1) not well-planned or well-coordinated and (2) localized in particular villages or cities. Most pogroms in Jewish history took place in the Russian Empire and its subsequent governments, but there have been pogroms in nearly every Old-World country that has hosted Jews other than India.
The pogroms were directed specifically against Jews.

Nazi Germany staged the Night of the Broken Glass, but on the whole preferred to avoid public disturbances when implementing its anti-Jewish policies. In 1941 there were pogroms in Romania, especially Bucharest and Iasi, with Jews being beaten up and killed in the street. One of the best know pogroms was that at Kishinev in 1903. See the link.
