The Mayo or Yoreme are an Indigenous group in Mexico, living in southern Sonora, northern Sinaloa and small settlements in Durango.

They own traditional authorities, who are elected by vote and their hierarchy is respected on par with the Mexican civil laws.

On arrival of the Spaniards in the present-day states of Sonora and Sinaloa, the Mayos were part of an Indian confederacy with the Apaches, Pima, and Yaqui.

Their purpose was the joint defense of the invasion of other groups, mutual respect for their territory, and cultural exchange.

In 1740 marked an armed uprising, which ended with victory again for the Spanish, after which a period of peace lasted almost a century.
