According to a recent book published by Historian Michael Fischbach, Black Power and Palestine, the SNCC, the Student Non-Violent Coordinating Committee, one of the main advocacy bodies for black emancipation during the civil rights era in the USA, in its June-July newsletter in 1967 raised questions about Israel and Zionism and which led to a backlash, resulting in a significant drop in donor support.
In fact the article itself took the form of a two-page spread titled Third World Round Up: The Palestine Problem: Test Your Knowledge and was compiled by editor Ethel Minor from a Palestine Research Center pamphlet titled, Do You Know? Twenty Basic Facts about the Palestine Problem and included cartoons by Kofi Bailey. In their preamble, they write:
In the past few weeks, the Arab-Israeli conflict exploded once again into an all out war as it did in 1956 and as it had done in 1948, when the State of Israel was created. What are the reasons for this prolonged conflict and permanent state of war which has existed between the Arab nations and Israel? Why has the United Nations, which helped create the problem, been unable to solve it? Why have hostilities continued? What is the root of the problem?
Since we know that the white American press seldom, if ever, gives the true story [sic] about world events in which America is involved, then we are taking this opportunity to present the following documented facts on this problem. These facts not only affect the lives of our brothers in the Middle East, Africa and Asia, but also pertain to our struggle here. We hope they will shed some light on the problem. Future issues of SNCC Newsletter will contain more background information and articles on the Arab-Israeli conflict.
In fact due to the ferocious backlash, there was one just one other issue that covered the sitation where they carefully contextualised the conflict.
Q. Is the earliest documented advocacy by a black civil rights group on behalf of Palestine? If not, what is the earliest?
Q. Was this the only intervention by the SNCC on Palestine or were there subsequent ones?
Given that my use of the term 'advocacy' has been questioned. I'm pointing out here that I'm using the term advocacy in its usual sense and I think that this holds since it appears that the SNCC itself was divided on how to tackle the situation - I imagine that the leadership would have on the whole expected the backlash - yet a determined faction was able to publish the article in the newsletter and also to promise a more detailed analysis. This counts as advocacy in my book.
