Historical discussion of the Almoravid and Almohad dynasties tends to conflate the two by labelling them both as Berber and “fundamentalist.” While both dynasties did, indeed, originate in Amazigh tribes from what is now Morocco, their interpretations of Islam were far from the same. Almoravids upheld the Maliki school of fiqh, whereas the Almohads adopted an early form of scripturalism, critical of the Maliki school, combined with ancient philosophy that committed exegesis through the use of reason. To see them as similar or a continuation of one another is a homogenization of their disparate ideological differences and likely arises from a tendency to view their influence as an incursion on an idealized understanding of Andalusian Islams and Iberia’s relegation to the status of an Amazigh colony under both polities. In this paper, I will briefly examine their theo-ideological differences, and other contingencies that separate the two dynasties. I will also examine their similarities and speculate as to the reason for their conflation among historians.
In the Medieval Iberia reader, the distinction between Almoravids and Almohads is ambiguous, partly because the source materials associated with them are lumped into the same chapter, and the dating of these materials can be a bit unclear. The dating of Ibn Abdun’s Hisba Manual is simply “early twelfth century,” which does not leave much information for the reader as to whether it was a specifically Almoravid or Almohad document. Its emphasis on Qur’anic or hadith stipulations for governing the marketplace leaves things up in the air as to who the document could have belonged to as both groups tended towards reinterpreting these key scriptural sources. That being said, the Almoravids did not break from the Maliki school of fiqh as the Almohads did and a thorough study of legal opinions from that school in relation to the prescriptions of this document might help to make the connection (or non-connection) to the Almoravids clearer. The one account we are provided with that is directly attributable to the Almoravids is Al-Idrisi’s Description of Almeria which says little of their ideological preferences or other distinguishing features. It appears that the Almoravids were very much interested in commerce, manufacturing and trade but the same can easily be said about the Almohads whose trade networks would later extend much farther east across the Mediterranean. The other documents in the chapter tend to focus on Almohad theology, their patronage and their treatment of the Jews. It could be that the source materials for the Almoravids in Iberia are simply not available or not directly attributable to them, which leads to a conflation of the two dynasties by virtue of source issues. Looking at how they are arranged in the Medieval Iberia reader is one example of this conflation.
At the beginning of his chapter entitled “Moroccan Fundamentalists” in Moorish Spain, Richard Fletcher notes that although the Almohads were of a remarkably different sect of fundamentalism from the Almoravids, the two groups are “confusingly similar” and “there is nothing that can be done about it.” Maria Rosa Menocal describes both the Almoravids and the Almohads as fundamentalist Berbers from Morocco. It seems that the term fundamentalism is being used here to imply a kind of intolerance based on literal applications of Islamic interpretations. The argument that these two are largely indistinguishable from each other, however, remains unconvincing and in the interests of not generalizing about these groups, it is important to find their key distinguishing features.
Constable argues that the Almohads are easier to trace based on their theological projections being clearer than the Almoravids who preceded them. Although Menocal (wrongfully) claims that the Almohad’s “narrow interpretation of Islam made their scholars far less avid than many Latin readers of [the] scientific and philosophical library,” their Almohad Creed is an excellent example of how the influence of Aristotelian metaphysics impacted Almohad interpretations of Islamic doctrine. Arguments made in the Creed were meant to be tested against one’s own Reason and lived experience in order to arrive at the truth of the Almohad ontology. Sources suggest that this approach was unique to the Almohads and was not shared by the Almoravids who exhibited their “fundamentalism” by extinguishing practices in al-Andalus that were against Islamic fiqh rulings but remained within that rigid framework.
Their differences in ideology are just one area we can use to nuance our demarcation between them. Al-Marrakushi’s history of the Almohads and Ibn Tumart’s rise and take over of Almoravid territory is a primary source document that helps to illustrate not only that these groups were different but that they were in contention with one another. The Almohads gained momentum quickly under Ibn Tumart’s leadership, conquering Almoravid territory in Morocco and into al-Andalus. In looking at their historical interaction, it sounds redundant to say, but these are obviously not the same group. I would go so far as to say that they are not the same brand of so-called fundamentalism either – a term problematic for its anachronistic connotations.
So, it remains, in what instances could it seem appropriate to put the Almoravids and Almohads in the same historical category together? Such an exercise might be useful from an Andalusian perspective as distinctions between the two groups might have been a moot point. The usurpation of power by the Almohads was still the unification of al-Andalus under a foreign polity – both polities which practiced radically different forms of Islam, not only from each other but from Andalusians themselves. In trying to uphold a narrative of Andalusian exceptionalism or preference for their cultural-religious practices, it would make sense to put two foreign, less cosmopolitan conquerors (who arrived one after the other) next to each other. For historians seeking to understand the differences between these two groups and to highlight the unique experience of Andalusians under each one, their conflation is of little value.
