Black supremacy is a collection of racialist ideologies that developed in response to white supremacy. Many of the largest black supremacist groups are black-Muslim separatist movements like the Nation of Islam.
The ideology of black supremacy, of course, is the mirror image of white supremacy. While different groups put their own spin on things, black supremacy often involves the racialist pseudoscience called "Melanin theory" and the pseudohistory called "Afrocentrism." The basic idea behind melanin theory is that black is the "natural" skin color because humans originated in Africa, so lighter skin tones are aberrations. Various melanin theorists build on top of this, positing all sorts of biologically unsupportable claims about melanin increasing muscle tone, brain activity, physical ability, etc. Some theories get into really batshit territory, claiming that melanin can grant paranormal powers like ESP.
Afrocentrism and melanin theory often cross-pollinate, but Afrocentrism as a separate concept has a historical rather than biological focus. It's important to separate legitimate historical revisionism from the kind Afrocentrists engage in. The early histories and ethnographies of African cultures were written largely by European historians and anthropologists from an imperialist perspective. Thus, these works are often filled with racism, factual inaccuracies, and are outdated due to new findings in archaeological and historical scholarship. There have been many revisionist works throughout the 20th and 21st centuries that attempt to look at this history from an African perspective, but remain factual. This is simply an attempt to "correct the record." Afrocentrism, on the other hand, engages in distortion and fabrications. The central claim of Afrocentrists is that Egypt was ruled by a black race. They use this to claim that Greco-Roman civilization, and by extension, Western civilization, is actually based on black culture. Working from this point, they rewrite many historical figures like Socrates as having been black and shoehorn various events into the ideology. When called on their bullshit, they tend to justify their factual inaccuracies by claiming that critics are using a Eurocentric methodology that is unable to ascertain a true understanding of history and that only those using the Afrocentric methodology can do so.
Oddly, some black supremacist groups have formed friendly relations with white supremacist groups. Part of it may be that both ideologies tend to promote anti-Semitism. Louis Farrakhan of the Nation of Islam invited the neo-Nazi Tom Metzger to NOI meetings. Metzger remarked:
“”They speak out against the Jews and the oppressors in Washington. . . . They are the black counterpart to us.
The black supremacist sect that probably most promotes anti-Semitism ironically identifies as "Black Hebrew Israelism." This ideology has its roots in post-bellum Pentecostalism, which transmuted into "Black Judaism." According to Black Judaism and Black Hebrew Israelism, the newly freed slaves of America's South were the true Hebrews and descendants of the tribes of Israel (an assertion that mirrors the Christian Identity theology held by some white supremacists, which claims Aryans as the true Hebrew race). F.S. Cherry, a late 19th century proponent of Black Judaism's more hateful elements, also preached about a race war with apocalyptic overtones that would supposedly occur in the year 2000 and refashion society into one where blacks were the superior race. The belief that blacks are the "true" Hebrews also leads many in the Black Hebrew Israelite movement to espouse anti-Semitic pseudohistory such as the Khazar myth and Holocaust denial.
