Michel Abitbol's Tombouctou et les arma is an important work on the history of the Pashalik of the Arma. Most people often ignore the 2 centuries or so of political and social history of Timbuktu and the Niger Bend after the fall of Songhay. Abitbol's work shows just how important that later, post-Songhay period was in terms of the Pashalik's political, social, economic, and regional importance. Indeed, the Pashalik persisted for so long partly because Timbuktu continued to be a major center for commerce and bridge between the Maghrib and the Sudan, long after the decline of al-Mansur's dynasty and the end of the Askias of Gao. However, even the Askias survived in a fashion, since a branch of them became close allies with the Arma regime. And while the authority of the Pashalik was later limited to Timbuktu, Djenne, Gao and other areas of the Niger Bend, and often became reduced to a ceremonial power of investiture for Tuareg chiefs who could sometimes attack or pillage the area with impunity, the Pashas continued to be the recognized authority of Timbuktu and a major power until the rise of Macina. Intriguingly, Abitbol believed the Arma, who became acclimatized and, later on, developing dominant families who dominated the position of pasha, despite the usually short tenures, were not a class per se. Instead, they were a leadership elite of essentially military origin and function. However, their alliance with the sharifs, ulama, merchants, Askias, and ownership of large numbers of slaves (who sometimes worked the land they owned) and dependents or haratins suggest something on the nature of a class society. The rather large corpus of sources used by Abitbol also suggests Timbuktu's importance in trans-Saharan trade retained its significance, too, surpassing in overall value the exports of other areas of the Sudan to North Africa. Clearly, there was a basis for great wealth accumulation and, in one case, a Pasha who even endeavored to emulate the great emperors of Mali and Songhay, possibly with the intention of recreating their grandeur for the Pashalik.
