VILLA DE LAS NAVAS DE SAN JUAN: History, independence and dignity privilege of villazgo and autonomy of Santisteban of port two stanzas in honor to my ancestors: woman of calle Sol to hut Montizon you prepare batches and small squares, while your chest protects the weeping, that mama between sweats and candelas. Man: Sweat, axe, South and hoe, felling rockrose, mastic trees and holm oaks, which die on charcoal fire and culminates in loaf of storms. Home Arab expulsion and extension of the kingdoms of Castile by the South of the Peninsula Iberica Alfonso VIII of Castile, along with Papa Inocencio III and Archbishop of Toledo, organized Christian crusade that motivates the Muslim siege. To which are added the troops of Sancho VII of Navarre, Pedro II of Aragon, Alfonso II of Portugal, different orders military, twenty councils Castellanos militias and thousands of native and ultramontanos volunteers that relentless advance to the encounter of the Almohads. The Christian troops cross by the troughs and the wooded mountains of Sierra Morena: historical sources territory called despenaperros in origin and memory to the cliff of multitude of captive Muslims in the battle of las Navas de Tolosa. To whom Christians considered dogs; and as such they released them for the high gorges that give passage and entry to the lands of Andalusia.
Earlier, however, the Almohad troops had been placed at points of strategic surveillance and Christians had to make their way out of the mountains, advance, and gain access to the plains of the Summit. However, on the future of the uncertainties are toparian with a pastor: Martin de Alhaja, who would indicate them the course of a trail that crosses the Sierra, and knows that by the name of Puerto del Rey. Troops that would organize and lead Alfonso VIII of Castile they would take that shortcut, and on 16 July 1212, previous skirmishes of little importance, reached the Summit and propagated by the plain, where located and attacked thousands of Muslims, led by the Almohad Caliph Muhammad An-Nasir, also known by Christians, through the nickname of Miramamolin.
