Palmaristas revolted and killed their peace-seeking king Ganga-Zumba in 1679

Evidence

By 1679, a palmarista “captain named Zambi (whose uncle is Gana-Zona) was in revolt (with) Joao mulato, Canhonga, Gaspar (and) Amaro, having done the person of Ganga-Zumba to death.” By March 1680, Zambi was being called upon to surrender, without success. The war was on once more. — Cedric J. Robinson, Black Marxism_ The Making of the Black…, 665
