The Massacre at the 11th Parallel occurred in November 1963,[1] when men hired by a rubber company killed 30 members of the indigenous Amazon group Cinta Larga and destroyed their village.
[5] The massacre took place in the headwaters of the Aripuanã River in Mato Grosso, at the 11th parallel south, where the Brazilian firm Arruda, Junqueira & Co was collecting rubber.
[2] The attack came to light when one of the perpetrators, Atayde Pereira dos Santos, reported it and those responsible to the Serviço de Proteção ao Índio (SPI) Inspectorate in Cuiabá, after not being paid the amount of money he had been promised.
[5] At the trial of one of the accused, the presiding judge said, "We have never listened to a case where there was so much violence, so much ignominy, egoism and savagery and so little appreciation of human life.
[2] The indigenous rights campaign group Survival International was founded in response to the report, two years after its original release by public prosecutor Jader de Figueiredo Correia.
