Origins The Almohad movement originated with
Ibn Tumart, a member of the
Masmuda, an
Amazigh tribal confederation of the
Atlas Mountains of southern Morocco. At the time, present-day Morocco, Mauritania, western Algeria and parts of Spain and Portugal (
al-Andalus) were under the rule of the
Almoravids, a
Sanhaja Berber dynasty. Early in his life, Ibn Tumart went to Spain to pursue his studies, and thereafter to
Baghdad to deepen them. In Baghdad, Ibn Tumart attached himself to the theological school of
al-Ash'ari, and came under the influence of the teacher
al-Ghazali. He soon developed his own system, combining the doctrines of various masters. Ibn Tumart's main principle was a strict unitarianism (
tawhid), which denied the independent existence of the
attributes of God as being incompatible with His unity, and therefore a polytheistic idea. Ibn Tumart represented a revolt against what he perceived as
anthropomorphism in Muslim orthodoxy. His followers would become known as the
al-Muwaḥḥidūn ("Almohads"), meaning those who affirm the unity of God. After his return to the
Maghreb c. 1117, Ibn Tumart spent some time in various
Ifriqiyan cities, preaching and agitating, heading riotous attacks on wine-shops and on other manifestations of laxity. He laid the blame for the latitude on the ruling dynasty of the Almoravids, whom he accused of obscurantism and impiety. He also opposed their sponsorship of the
Maliki school of jurisprudence, which drew upon consensus (
ijma) and other sources beyond the
Qur'an and
Sunnah in their reasoning, an anathema to the stricter
Zahirism favored by Ibn Tumart. His antics and fiery preaching led fed-up authorities to move him along from town to town. After being expelled from
Bejaia, Ibn Tumart set up camp in Mellala, in the outskirts of the city, where he received his first disciples – notably, al-Bashir (who would become his chief strategist) and
Abd al-Mu'min (a Zenata Berber of the Kumiya tribe who would later become his successor). In 1120, Ibn Tumart and his small band of followers proceeded to
Morocco, stopping first in
Fez, where he briefly engaged the Maliki scholars of the city in debate. He even went so far as to assault the sister of the
Almoravid emir
Ali ibn Yusuf, in the streets of Fez, because she was going about unveiled, after the manner of Berber women. After being expelled from Fez, he went to
Marrakesh, where he successfully tracked down the Almoravid emir Ali ibn Yusuf at a local mosque, and challenged the emir, and the leading scholars of the area, to a doctrinal debate. After the debate, the scholars concluded that Ibn Tumart's views were blasphemous and the man dangerous, and urged him to be put to death or imprisoned. But the emir decided merely to expel him from the city. Ibn Tumart took refuge among his own people, the Hargha, in his home village of Igiliz (exact location uncertain), in the
Sous valley. He retreated to a nearby cave, and lived out an ascetic lifestyle, coming out only to preach his program of puritan reform, attracting greater and greater crowds. At length, towards the end of
Ramadan in late 1121, after a particularly moving sermon, reviewing his failure to persuade the Almoravids to reform by argument, Ibn Tumart 'revealed' himself as the true
Mahdi, a divinely guided judge and lawgiver, and was recognized as such by his audience. This was effectively a declaration of war on the Almoravid state. On the advice of one of his followers,
Omar Hintati, a prominent chieftain of the
Hintata, Ibn Tumart abandoned his cave in 1122 and went up into the
High Atlas, to organize the Almohad movement among the highland
Masmuda tribes. Besides his own tribe, the Hargha, Ibn Tumart secured the adherence of the Ganfisa, the Gadmiwa, the Hintata, the Haskura, and the Hazraja to the Almohad cause. Sometime around 1124, Ibn Tumart established his base at
Tinmel, a highly defensible position in the valley of the Nfis in the High Atlas. Tinmal would serve both as the spiritual center and military headquarters of the Almohad movement. It became their (roughly 'place of retreat'), emulating the story of the
hijra (journey) of
Muhammad's to
Medina in the 7th century. For the first eight years, the Almohad rebellion was limited to a guerilla war along the peaks and ravines of the High Atlas. Their principal damage was in rendering insecure (or altogether impassable) the roads and mountain passes south of Marrakesh – threatening the route to all-important
Sijilmassa, the gateway of the
trans-Saharan trade. Unable to send enough manpower through the narrow passes to dislodge the Almohad rebels from their easily defended mountain strong points, the Almoravid authorities reconciled themselves to setting up strongholds to confine them there (most famously the fortress of
Tasghîmût that protected the approach to
Aghmat, which was conquered by the Almohads in 1132), while exploring alternative routes through more easterly passes. Ibn Tumart organized the Almohads as a commune, with a minutely detailed structure. At the core was the
Ahl ad-dār ("House of the Mahdi"), composed of Ibn Tumart's family. This was supplemented by two councils: an inner
Council of Ten, the Mahdi's privy council, composed of his earliest and closest companions; and the consultative Council of Fifty, composed of the leading
sheikhs of the Masmuda tribes. The early preachers and missionaries (
ṭalaba and
huffāẓ) also had their representatives. Militarily, there was a strict hierarchy of units. The Hargha tribe coming first (although not strictly ethnic; it included many "honorary" or "adopted" tribesmen from other ethnicities, e.g. Abd al-Mu'min himself). This was followed by the men of Tinmel, then the other Masmuda tribes in order, and rounded off by the black fighters, the
ʻabīd. Each unit had a strict internal hierarchy, headed by a
mohtasib, and divided into two factions: one for the early adherents, another for the late adherents, each headed by a
mizwar (or
amzwaru); then came the
sakkakin (treasurers), effectively the money-minters, tax-collectors, and bursars, then came the regular army (
jund), then the religious corps – the
muezzins, the
hafidh and the
hizb – followed by the archers, the conscripts, and the slaves. Ibn Tumart's closest companion and chief strategist, al-Bashir, took upon himself the role of "
political commissar", enforcing doctrinal discipline among the Masmuda tribesmen, often with a heavy hand. In early 1130, the Almohads finally descended from the mountains for their first sizeable attack in the lowlands. It was a disaster for their opponents. The Almohads swept aside an Almoravid column that had come out to meet them before Aghmat, and then chased their remnant all the way to Marrakesh. They laid siege to Marrakesh for forty days until, in April (or May) 1130, the Almoravids sallied from the city and crushed the Almohads in the bloody
Battle of al-Buhayra (named after a large garden east of the city). The Almohads were thoroughly routed, with huge losses. Half their leadership was killed in action, and the survivors only just managed to scramble back to the mountains.
Caliphate and expansion Ibn Tumart died shortly after, in August 1130. That the Almohad movement did not immediately collapse after such a devastating defeat and the death of their charismatic Mahdi, is likely due to the skills of his successor,
Abd al-Mu'min. Ibn Tumart's death was kept a secret for three years, a period which Almohad chroniclers described as a
ghayba or "occultation". This period likely gave Abd al-Mu'min time to secure his position as successor to the political leadership of the movement. Although a
Zenata Berber from Tagra (Algeria), and thus an alien among the Masmuda of southern Morocco, Abd al-Mu'min nonetheless saw off his principal rivals and hammered wavering tribes back to the fold. Three years after Ibn Tumart's death he was officially proclaimed "Caliph". After 1133, Abd al-Mu'min quickly expanded Almohad control across the Maghreb, while the embattled Almoravids retained their capital in Marrakesh. Various other tribes rallied to the Almohads or to the Almoravids as the war between them continued. Initially, Almohad operations were limited to the Atlas mountains. In 1139, they expanded to the
Rif mountains in the north. One of their early bases beyond the mountains was
Taza, where Abd al-Mu"min founded a citadel (
ribat) and a
Great Mosque circa 1142. The Almoravid ruler, Ali ibn Yusuf, died in 1143 and was succeeded by his son,
Tashfin ibn Ali. The tide turned more definitively in favour of the Almohads from 1144 onwards, when the Zenata tribes in what is now western Algeria joined the Almohad camp, along with some of the previously Almoravid-aligned leaders of the
Masufa tribe. This allowed them to defeat Tashfin decisively and capture
Tlemcen in 1144. Tashfin fled to
Oran, which the Almohads then attacked and captured, and he died in March 1145 while trying to escape. They were specifically settled into the
Atlantic plains of Morocco which was previously depopulated by the Almohads. There was also a significant amount of Arab and Berber intermarriage which led to the spread of Arabic language and restructuring of tribal structures. These plains are inhabited today by the descendants of these Arab tribes known as the
ʕroubiya – a name that literally means "Bedouins". Abd al-Mu'min spent the mid-1150s organizing the Almohad state and arranging for power to be passed on through his family line. In 1154, he declared his son Muhammad as his heir. In order to neutralise the power of the Masmuda, he relied on his tribe of origin, the Kumiyas (from the central Maghreb), whom he integrated into the Almohad power structure and from whom he recruited some 40,000 into the army. They would later form the bodyguard of the caliph and his successors. In addition, Abd al-Mu'min relied on Arabs, the great Hilalian families that he had deported to Morocco, to further weaken the influence of the Masmuda sheikhs. These Arabs became embedded in the Almohad elite to the point that they became partners in giving the
bay‘a to a new caliph and formed the most important contingents in the Almohad military in
Ifriqiya, al-Andalus and the provinces. With his son appointed as his successor, Abd al-Mu'min placed his other children as governors of the provinces of the caliphate. His sons and descendants became known as the
sayyids ("nobles").
Holding years In 1212, the Almohad Caliph
Muhammad 'al-Nasir' (1199–1214), the successor of al-Mansur, after an initially successful advance north, was defeated by an alliance of the three Christian kings of
Castile,
Aragón and
Navarre at the
Battle of Las Navas de Tolosa in the
Sierra Morena. The battle broke the Almohad advance, but the Christian powers remained too disorganized to profit from it immediately. Before his death in 1213, al-Nasir appointed his young ten-year-old son as the next
caliph Yusuf II "al-Mustansir". The Almohads passed through a period of effective
regency for the young caliph, with power exercised by an oligarchy of elder family members, palace bureaucrats and leading nobles. The Almohad ministers were careful to negotiate a series of truces with the Christian kingdoms, which remained more-or-less in place for next fifteen years (the
loss of Alcácer do Sal to the
Kingdom of Portugal in 1217 was an exception). In early 1224, the youthful caliph died in an accident, without any heirs. The palace bureaucrats in
Marrakesh, led by the
wazir Uthman ibn Jam'i, quickly engineered the election of his elderly grand-uncle,
Abd al-Wahid I 'al-Makhlu', as the new Almohad caliph. But the rapid appointment upset other branches of the family, notably the brothers of the late al-Nasir, who governed in
al-Andalus. The challenge was immediately raised by one of them, then governor in
Murcia, who declared himself Caliph
Abdallah al-Adil. With the help of his brothers, he quickly seized control of al-Andalus. His chief advisor, the shadowy Abu Zayd ibn Yujjan, tapped into his contacts in Marrakesh, and secured the
deposition and assassination of Abd al-Wahid I, and the expulsion of the al-Jami'i
clan. This
coup has been characterized as the pebble that finally broke al-Andalus. It was the first internal coup among the Almohads. The Almohad clan, despite occasional disagreements, had always remained tightly knit and loyally behind dynastic precedence. Caliph al-Adil's murderous breach of dynastic and constitutional propriety marred his acceptability to other Almohad
sheikhs. One of the recusants was his cousin, Abd Allah al-Bayyasi ("the
Baezan"), the Almohad governor of
Jaén, who took a handful of followers and decamped for the hills around Baeza. He set up a rebel camp and forged an alliance with the hitherto quiet
Ferdinand III of Castile. Sensing his greater priority was Marrakesh, where recusant Almohad
sheikhs had rallied behind Yahya, another son of al-Nasir, al-Adil paid little attention to them.
Decline in al-Andalus In 1225, Abd Allah al-Bayyasi's band of rebels, accompanied by a large Castilian army, descended from the hills, besieging cities such as
Jaén and
Andújar. They
raided throughout the regions of
Jaén,
Córdoba and
Vega de Granada and, before the end of the year, al-Bayyasi had established himself in the city of
Córdoba. Sensing a power vacuum, both
Alfonso IX of León and
Sancho II of Portugal opportunistically ordered raids into Andalusian territory that same year. With Almohad arms, men and cash dispatched to Morocco to help Caliph al-Adil impose himself in Marrakesh, there was little means to stop the sudden onslaught. In late 1225, with surprising ease, the Portuguese raiders reached the environs of
Seville. Knowing they were outnumbered, the Almohad governors of the city refused to confront the Portuguese raiders, prompting the disgusted population of Seville to take matters into their own hands, raise a militia, and go out in the field by themselves. The result was a veritable massacre – the Portuguese men-at-arms easily mowed down the throng of poorly armed townsfolk. Thousands, perhaps as much as 20,000, were said to have been slain before the walls of Seville. A similar disaster befell a similar popular levy by
Murcians at
Aspe that same year. But Christian raiders had been stopped at
Cáceres and
Requena. Trust in the Almohad leadership was severely shaken by these events – the disasters were promptly blamed on the distractions of Caliph al-Adil and the incompetence and cowardice of his lieutenants, the successes credited to non-Almohad local leaders who rallied defenses. But al-Adil's fortunes were briefly buoyed. In payment for Castilian assistance, al-Bayyasi had given Ferdinand III three strategic frontier fortresses:
Baños de la Encina, Salvatierra (the old
Order of Calatrava fortress near
Ciudad Real) and
Capilla. But Capilla refused to surrender, forcing the Castilians to lay a long and difficult siege. The brave defiance of little Capilla, and the spectacle of al-Bayyasi's shipping provisions to the Castilian besiegers, shocked Andalusians and shifted sentiment back towards the Almohad caliph. A popular
uprising broke out in Córdoba – al-Bayyasi was killed and his head dispatched as a trophy to Marrakesh. But Caliph al-Adil did not rejoice in this victory for long – he was assassinated in Marrakesh in October 1227, by the partisans of Yahya, who was promptly acclaimed as the new Almohad caliph
Yahya "al-Mu'tasim". The Andalusian branch of the Almohads refused to accept this turn of events. Al-Adil's brother, then in Seville, proclaimed himself the new Almohad caliph
Abd al-Ala Idris I 'al-Ma'mun'. He promptly purchased a
truce from Ferdinand III in return for 300,000
maravedis, allowing him to organize and dispatch the greater part of the Almohad army in Spain across the
straits in 1228 to confront Yahya. That same year, Portuguese and
Leonese renewed their raids deep into Muslim territory, basically unchecked. Feeling the Almohads had failed to protect them, popular uprisings took place throughout al-Andalus. City after city deposed their hapless Almohad governors and installed local strongmen in their place. A Murcian strongman,
Ibn Hud, who claimed descendance from the
Banu Hud dynasty that had once ruled the old
taifa of Saragossa, emerged as the central figure of these rebellions, systematically dislodging Almohad garrisons through central Spain. In October 1228, with Spain practically all lost, al-Ma'mun abandoned Seville, taking what little remained of the Almohad army with him to Morocco. Ibn Hud immediately dispatched emissaries to distant
Baghdad to offer recognition to the
Abbasid Caliph, albeit taking up for himself a quasi-caliphal title, 'al-Mutawwakil'. The departure of al-Ma'mun in 1228 marked the end of the Almohad era in Spain. Ibn Hud and the other local Andalusian strongmen were unable to stem the rising flood of Christian attacks, launched almost yearly by
Sancho II of Portugal,
Alfonso IX of León,
Ferdinand III of Castile and
James I of Aragon. The next twenty years saw a massive advance in the Christian
reconquista – the old great Andalusian
citadels fell in a grand sweep:
Mérida and
Badajoz in 1230 (to Leon),
Mallorca in 1230 (to Aragon),
Beja in 1234 (to Portugal),
Córdoba in 1236 (to Castile),
Valencia in 1238 (to Aragon),
Niebla-
Huelva in 1238 (to Leon),
Silves in 1242 (to Portugal),
Murcia in 1243 (to Castile),
Jaén in 1246 (to Castile),
Alicante in 1248 (to Castile), culminating in the fall of the greatest of Andalusian cities, the ex-Almohad capital of
Seville, into Christian hands in 1248. Ferdinand III of Castile entered Seville as a conqueror on December 22, 1248. The Andalusians were helpless before this onslaught. Ibn Hud had attempted to check the Leonese advance early on, but most of his Andalusian army was destroyed at the
battle of Alange in 1230. Ibn Hud scrambled to move remaining arms and men to save threatened or besieged Andalusian citadels, but with so many attacks at once, it was a hopeless endeavor. After Ibn Hud's death in 1238, some of the Andalusian cities, in a last-ditch effort to save themselves, offered themselves once again to the Almohads, but to no avail. The Almohads would not return. With the departure of the Almohads, the
Nasrid dynasty ("
Banū Naṣr", ) rose to power in
Granada. After the great Christian advance of 1228–1248, the
Emirate of Granada was practically all that remained of old
al-Andalus. Some of the captured citadels (e.g. Murcia, Jaen, Niebla) were reorganized as tributary vassals for a few more years, but most were annexed by the 1260s. Granada alone would remain independent for an additional 250 years, flourishing as the new center of al-Andalus.
Collapse in the Maghreb In their African holdings, the Almohads encouraged the establishment of Christians even in
Fez, and after the
Battle of Las Navas de Tolosa they occasionally entered into alliances with the kings of
Castile. The history of their decline differs from that of the Almoravids, whom they had displaced. They were not assailed by a great religious movement, but lost territories, piecemeal, by the revolt of tribes and districts. Their most effective enemies were the Banu Marin (
Marinids) who founded the next dynasty. The last representative of the line,
Idris al-Wathiq, was reduced to the possession of
Marrakesh, where he was murdered by a slave in 1269. == Government ==
