First Book of Chronicles (Of Lions and Falcons)

"That tells of the events after the victory of the Almohad at Navas de Tolosa, the further victories and advances of the Almohad, the querrels between Castile and Leon and the triumphs of Aragon in Occitania"

Battle of Las Navas de Tolosa
In 16 july of 1212 (15 Safar 609 AH) Battle of Las Navas de Tolosa the Christian Army was defeated by the ]Almohad. The Order of Calatrava loses its Grand Master in the Battle. King Alfonso VIII of Castile died in battle and a regency under Eleanor Plantagenet was established.

The Castilian and Leonese Wars
However besides losing a King Castile had greater troubles and dire times. Alfonso IX of Leon pressed to regain his territorial claims by the arms with his army and Christian and Arab mercenaries starting th the first of the Castilian-Leonese Wars, in 1213. Eleanor Plantagenet has guardian of the heir Enrique I and a politically resourceful woman surrounded herself with loyal counselors and generals. The first moves of Leon meant a brief struggle to gain the control of Segovia from the hands of Castile, helped by a treacherous Leonese tribute offered to the Almohad to prevent an strike from them. A brief truce was settled but now Alfonso IX became more ambitious and planned to have all or greater part of Castile has part of his domains.

The Spoils of Victory
After his Victory, Caliph Muhammad al-Nasir looked to further consolidate his gains. The siege and recapture of Calatrava La Vieja ( Qal'at Rabah) and Malagon by Almohad and mercenary armies in 1212 (609 AH) established for the control of this area for future campaigns. On his return to Ishbiliya (Sevilla) he called on his general to plan the next campaign to regain Alentejo from Portugal.

So in 1214 (610-6111 AH) under his command he led the First Almohad Summer Campaign of Alentejo. Its gains were the recapture of Evora (Portuguese 1165-1214) and consolidation of southern half of Alentejo. It was also followed by the military expulsion of the Order of Aviz from Evora and to move its headquarters to Santarem.

However Muhammad al-Nasir had to turn his attention to North Africa, saving the Portuguese for the time from further military campaigns. In 1215 the Marinids (Banu Marin) rebelled and took control of Bugia, Argel and al-Mansoura. More alarming was the proclamation of Abd al-Haqq I, leader of the Marinids, of his allegiance to the Abbasid Caliphate and disdain to the so called Almohad heretics. A center of dissident and resistance to Almohad orthodoxy came to being, so a mutual jihad was proclaimed. In 1217 (613-614 AH) Muhammad al-Nasir, along his general Uzair al-Jasmir and Abu Zakariya Yahya governor of Ifriqiya, started the jihad against the despicable Marinids (1215-1217). The Victory of Alger of the Almohad in 1217 ended the rule of the Banu Marin (Marinids) in Argelia. With his hands free again the campaigns (jihad) of Alentejo were restarted.

However the Caliph’s generals were not idle in Al-Andalus, also important were the victories at the sieges of Alcántara (August-September 1216) and Uncles (October 1216). Each were respectively the seat of the military orders of Alcantara and Santiago and their defeat meant their retreat to the north of Tagus river.

Greater news arrived from Al-Andalus. Taking advantage of the Castilian-Leonese Wars and a truce with the former kingdom, the Almohad recaptured Toledo (May 1218, Safar 615 AH) and ratified and consolidate their control of the southern bank of Tagus river. Followed later by the Second Almohad Summer Campaign of Alentejo (1219, 615-616 AH) that to the despair of the Portuguese meant further defeats and losses.

Victory of Muret and Cathar Crusade
For Pedro II The Catholic of Aragon the campaign and defeat of Las Navas de Tolosa had already settled his unwillingness to campaign in Spain. His main interest had been on Occitania. Returning to Aragon in 1212 he finds that Simon IV of Montfort had conquered Toulouse, exiling Count Raymond VI of Toulouse, who was Peter's brother-in-law and vassal. He decided to cross the Pyrenees and deal with Montfort at Muret. Arriving at Muret in September 1213 to confront Montfort's army. The siege of Muret was won when a the small contingent commanded by Montfort attacked the Aragonese forces the 13th in order to lift and escape the siege. In combat Montford is killed causing his forces to dispel and surrender Muret. Pedro II's victory leaves him has overlord of great part of the Languedoc. He negotiated with the papal delegate to continue and command the Albigensian Crusade in exchange of the repealment of the papal excommunication and recognition of his suzerainty of Toulouse, Montpellier, Foix and Provence.

Under pressure and demands from his Aragonese vassals and merchants, Pedro II commanded the siege of Castellon (november 1216). Its victory and short reach (60 Km) from Balansīa (Valencia) was appropriate for continuous raids to its countryside and strangle its defenses and resources. In vain for the time being did the Arab governor of Balansīa plead for help from the Caliph.

In 1220 (616–617 AH) the Estats de Toulouse summoned by Pedro II The Catholic of Aragón, assembled for the first time. Its first business was to recognize the suzerainty of the Crown of Aragon in Occitania.

New gains and contacts
Out of the Almohad domains of Morocco, Argelia, Ifriqiya, Al-Andalus and Balearic Islands laid other people and lands. For example the Eternal Islands (Al-Jaza'ir al-Khalidat), occasionally visited by Muslim ships and sailors and some Christians. The Eternal Islands are inhabitant by the Guanches, indigenous people of Berber extraction. On the knowledge of their existence the Caliph decided to spreadd the word and book of God to them and give them his protection. So in the 1250s the Kingdoms of the Canary Island became vassals of the Almohad and were place under its protection and commerce.

The main Muslim Sahelians polities (Mail and Songhai Empires) had long established commercial ties with the Maghreb, and also diplomatic contacts exchanging scholars and learning.
