The fundamental laws of the Diné, "the People" in the Navajo language, were placed by the Holy People long before Spaniards arrived in the New World. Since Coronado first traveled to Navajo Country almost five centuries ago, Diné have resisted European assaults on Navajo Law. On November 1, 2002, the Navajo Nation Council acknowledged the survival of the fundamental laws of the Diné, recognizing four specific constituent elements — traditional law, customary law, natural law, and common law – and explaining the principles of each.
