Tallán (or Tacllán, after the use of the taclla, a farming tool) was a conglomerate of ethnic groups with a common origin that settled in the plains of north-western Peru, an ethnos with a matriarchal system. (Due to their possible kinship, the tumpis, who settled in the current Department of Tumbes, are widely considered one of these ethnic groups.) They had migrated to the coastal plains from the Sierra.
