So this woman got a wikipedia page in both pt and en
Whats the problem? Its all false. Basically, Dandara as the wife of the last king of the black enclave of Palmares (which was where escaped slaves lived in the 17th century in Brazil), who commited suicide to avoid being made a slave again, was made up in the 90's when the first president after the end of the Ditactorship mandated a "heroes of the country" book.
Basically, all we know of Dandara is that she existed, all reports of the time never list any wife for the king in question (Zumbi), despite african rulers normally having multiple wives, in fact some modern books even give names to the supposed children of the "couple", as Motumbo, Harmódio and Aristogíton. The first is a very generic name, basically the brazilian "Mandingo", and the other 2 are the translation of Trojan heroes, because illetrate slaves in Brazil would know about the Illiad?
And now, her name replaced the Princess Isabel's plaque in a street, Isabel was the one who ended the slavery in the country, acting as a regent while her father was in a trip in Europe and Egypt.
