1009–1031 CEThe collapse of the Caliphate
فِتْنَةُ قُرْطُبَة
After the strong rule of the chamberlain al-Mansur (Almanzor), who dominated the state in the late tenth century, the Cordoban Caliphate fell into civil war (the fitna). Rival claimants, Berber and Slav factions, and the weakness of the later Umayyads tore the unified state apart. In 1031 the caliphate was formally abolished, and al-Andalus fragmented into a patchwork of small kingdoms.
Significance: The end of a unified Andalusi state. Political fragmentation left Muslim Iberia militarily vulnerable to the expanding Christian kingdoms of the north.
1031–1091 CEThe Taifa kingdoms
مُلُوكُ الطَّوَائِف
In place of the caliphate arose dozens of independent city-states (muluk al-tawa'if), centred on cities such as Seville, Granada, Toledo, Zaragoza and Almeria. Politically divided and often at war with one another, the taifas were nonetheless a brilliant age for culture: their courts competed in patronising poets, scholars and scientists. Their weakness, however, forced many to pay tribute (parias) to Christian rulers, and the fall of Toledo to Castile in 1085 alarmed the whole Muslim south.
Significance: A paradox of the era: cultural splendour amid political weakness. Disunity and tribute to Christian powers prepared the way for intervention from North Africa.
1086 CE / 479 AHThe Almoravids (al-Murabitun)
المُرابِطُون
Facing Christian advances, the taifa rulers appealed to the Almoravids, a reformist Berber movement that had built an empire across the Maghrib. Led by Yusuf ibn Tashfin, they crossed into Iberia and defeated King Alfonso VI of Castile at the Battle of Sagrajas (Zallaqa) in 1086. Within a few years they had annexed most of the taifas, reuniting al-Andalus under a stern, religiously austere rule centred on Marrakesh.
Significance: North African intervention halted the Christian advance for a time and re-unified al-Andalus, though Almoravid rule was resented by some Andalusis as harsh and foreign.
1147 CE / 541 AHThe Almohads (al-Muwahhidun)
المُوَحِّدُون
A second Berber movement, the Almohads — followers of the doctrine of Ibn Tumart — overthrew the Almoravids in the Maghrib and crossed into al-Andalus around 1147. They governed from Seville, raised great monuments such as its mosque (whose minaret survives as the Giralda), and patronised philosophers including Ibn Rushd and Ibn Tufayl. Their power was broken by a decisive Christian victory at Las Navas de Tolosa in 1212, after which their hold on Iberia rapidly unravelled.
Significance: Despite its cultural patronage, the Almohad collapse after 1212 opened the way for a rapid Christian reconquest of most of the peninsula in the thirteenth century.
