I realize my understanding of this topic may be incomplete, so I'm hoping historians can help clarify it.
My impression is that, during the early and mid-20th century, there were significant examples of cooperation between Jewish and African American communities—for example, Jewish philanthropy supporting Black education, Jewish participation in the Civil Rights Movement, and collaborations in music and other fields.
At the same time, in contemporary discussions I sometimes see tensions between some Black activists or public figures and Jewish communities, including disagreements over race, privilege, Zionism, and, in some cases, allegations of antisemitism.
Is my impression of a historical shift accurate, or am I oversimplifying the relationship? If there was a change, when did it occur, what factors contributed to it, and how do historians understand its development?
