Jews were a key part of the civil rights movement in the 1960s. When the Reverend Martin Luther King Jr. made his famous march to Selma Alabama, he walked hand in hand with many Jews including Rabbi Abraham Joshua Heschel. Along with the Jews was a contingent of Torahs to emphasize that the quest for Blacks Civil Rights was a holy mission for the Jewish people.
In spite of the strong Jewish participation in the civil rights movement, the transformation from the peaceful marches to Black power movement introduced considerable friction into African American-Jewish relations, especially within the “Black Muslim” movement.
After the murder of Martin Luther King Jr. leadership of the Civil Rights movement was inherited by people like Jesse Jackson who saw the Jews as their competition for achieving middle-class status. Black leaders such as Jackson and Louis Farrakhan went public with anti-Semitic comments.
Adding to the hatred were the leaders of the South African anti-Apartheid movement who traveled throughout the United States as conquering heroes, and spreading Jew-hatred. For example, in 1984 Desmond Tutu publicly complained about American Jews having “an arrogance—the arrogance of power because Jews are a powerful lobby in this land and all kinds of people woo their support.
Understandably Jewish/Black relations were already rocky as NY City entered the summer of 1991.
On July 20, 1991, Leonard Jeffries of City College who had a history of anti-Semitic slurs presented a two-hour long speech claiming “rich Jews” financed the slave trade, Jews control the film industry (together with Italian mafia), and use that control to paint a brutal stereotype of blacks. Jeffries also attacked Diane Ravitch, (Assistant Secretary of Education) calling her a “sophisticated Texas Jew,” “a debonair racist” and “Miss Daisy.”
Jeffries’ speech received enormous negative press during the first weeks of August especially from the leaders of the Jewish community who wanted Jeffries fired for the bigotry.
With each new criticism of the professor, leaders in the African-American community rushed to Jeffries’ defense. NYC’s two black newspapers as well as black radio station WLIB; joined activists such Al Sharpton, Colin Moore, C. Vernon Mason, Sonny Carson, and Lenora Fulani to showcase their approval of Jeffries’s “scholarship” and to denounce the people who criticized Jeffries Antisemitism as race baiters.
Sharpton has been credited with saying, “If the Jews want to get it on, tell them to pin their yarmulkes back and come over to my house” as a response the Crown Heights riot. That is a fallacy; he made that threatening comment about the growing Jeffries controversy on August 18th the day before the riots began. Clearly, something bad was coming.
Jeffries was fired because of his bigoted speech and pressure from the Jewish community (he was later reinstated and won a court case surrounding his firing) leading to further resentment of the Jews from a Black community already being barraged with anti-Jewish incitement from the local African-American media.
