The Hênia-Kâmîare aboriginals inhabited the current territory of the Sierras de Córdoba for at least 1600 years. In 1575, the resistance led by cacique Onga was cornered and defeated by the Spanish conquering troops. Hundreds of Hênia-Kâmîare women, children, and elders jumped off the top of the Colchoquí mountain in order to avoid being enslaved. This was the biggest collective suicide in the territory currently known as Argentina.
