Eleven thousand years ago, Atacama was already inhabited by groups of hunter-gatherers of the San Pedro or Atacama cultures. The passage of the Tiahuanaco and Inca cultures and later on the arrival of the Spanish conquistadors had a major influence on the Atacama culture, which was forced to integrate in order not to disappear. The population is currently made up of descendants of the first inhabitants of the region, Atacameños and European colonists, with a strong Chilean and Quechua influence.
