Woman - Brazilian Amazon Warriors: Icamiabas
European colonizers, in 1541, claimed to have encountered a tribe of warrior women Indigenous, called Icamiabas, with whom they had fought.
After the European colonizers had to retreat following the attack with blowgun and archery when entered in their territory, so associated the girls with the Amazons of Greek mythology, thus naming the place "River of the Amazons", today called "River Amazon " (but it was previously called Paraná-Assú by the indigenous people of old, meaning 'large similar to the sea'. Really, it's the largest river by discharge volume of water in the world).
Because of this, not only is the river today called the Amazon River, but this became the name of that Brazilian state (Amazonas), once the location of the legend, and also where the name of the largest tropical forest in the world derived from: Amazon Forest.
Legend has it that Icamiabas it was a nation of women, made up of a matriarchal society, characterized by female warriors who lived without men.
Once a year, some of the girls willingly welcomed men from other tribes during the "Festa de Iaci" ('Festival of the Moon') according to which, in order to procreate, at the end the womans dived into the river where took a green material to carve a muiraquitã*, which they gave to men (*a traditional indigenous amulet related to the Icamiabas, it was symbols of power, status and honor, and also as material for purchasing and exchanging others valuable objects).
After the festival, the Brazilian Amazons lived alone again. The girls babies born from these unions remained with the 'Amazons/Icamiabas', while the boys were perhaps given to the men with the amulet in the following year, but some darker versions of the legend believe that they killed male babies.
It received the status of a legend, because beyond the European and Indigenous report, it is not really known whether they existed and there is controversy, among those who believe and do not believe in the existence of these womans.
