Jean-Claude Zelter's Tripoli, carrefour de l'Europe et des pays du Tchad, 1500-1795 is one of those studies of Tripoli that we believed was necessary to understand the North African side of Kanem-Borno's trans-Saharan trade. Due to Zeltner's specialization in the Chadian past and research in Kanem and among the Awlad Sulayman Arabs, we hoped his history of Tripoli would integrate the histories of Tripolitania and the Central Sudan. Unfortunately, a deeper integration of the two remains to be written but this is an interesting start. Indeed, Zeltner fits the history of Tripoli in both a Mediterranean and trans-Saharan context. Indeed, without Europe, the Chad Basin and the bridges of the Mediterranean and Sahara, Tripoli was economically marginal. This indicates how a major North African port relied so heavily on the African interior and Europe and the economic integration of Africa and Europe (and the Levant).
Outside of corsair activity targeting European ships and enslaving the victims, the trade in slaves and other "goods" acquired the trans-Saharan trade was the main source of revenue for the rulers (beys and pashas) of Tripoli from c.1500-1795. Moreover, as Zeltner takes great pains to indicate, most of the goods traded further south to Borno or sub-Saharan Africa via Tripoli came from Europe, especially Italy and even France. Thus, the trans-Saharan trade of the Central Sudan was directly linked to Mediterranean and European economies. Zeltner seems to have believed that had the Holy Roman Empire under Charles V or another European power had permanently established control of Tripoli and the Barbary coast, European trade with the African interior through the Sahara could have developed fully without the constant attacks of pirates or, in the case of Tripoli, frequent revolutions and unseating of pashas. But that's neither here nor there. Perhaps it is best to see Zeltner's overview of Tripoli's history in an attempt to show how the North African port served a vital role in connecting various regional or really global economies. Future studies could probably, assuming more data is accumulated or discovered, link developments in Tripoli and Fezzan with specific economic and political affairs in the Central Sudan or Borno.
Unfortunately, there are some problems with Zeltner's approach and the structure of the book. The first 100 pages delve into the larger conflicts between the Ottoman Empire and the Holy Roman Empire in the Mediterranean. It is definitely important for understanding how Tripoli fell under the control of Turgut, but it may be excessive to spend so many pages on the period leading up to 1551. Perhaps it would have been good to cover Wadai in the 17th and 18th centuries, too, for an additional kingdom trading with Tripoli and the Libyan coast. Fuller coverage of what was going on in the Central Sudan during the period, in addition to the reign of Idris b. Ali of Borno, could have been juxtaposed with Tripoli's various conflicts with the English, French and other Europeans in the Mediterranean. That could have better emphasized how events or political, social, and religious changes in the Central Sudan had an impact on Tripoli and the Mediterranean, not just Tripoli's political or social changes influencing the Fezzan and "Sudan" to the south. It was also confusing to see Zeltner equate Kwararafa with the Mandara kingdom, despite evidence linking it to the Jukun peoples.
Nevertheless, Zeltner's book is a good introduction to Tripoli that helps us better understand the Tripoli chronicle previously read for this site. Some of the particularities of Barbary piracy, Ottoman interests in the Mediterranean and even the role of the French in shipping African captives in Tripoli to the Levant were especially interesting. The frequent coups and revolutions and the way in which Tripoli, for a time, benefitted from French and English rivalry in the Mediterranean was likewise intriguing and perhaps brings to mind the ways in which banditry in the Sahara and Sahel had its counterpart on sea with the corsairs and rivalry between Sudanic states or kingdoms. Banditry and business go hand in hand, despite the former occasionally hurting the latter.
