By the 15th century, the mythology of the coat of arms would trace its origin back to the Battle of Las Navas de Tolosa in 1212 involving Sancho VII of Navarre, where the cavalry broke the chains of the caliph's slave-warriors and captured an emerald, among other prizes. Following the Spanish conquest of Iberian Navarre in 1512, the coat of arms of Navarre was incorporated into the coat of arms of Spain, and it is currently positioned as the fourth quarter.
