Using diplomatic records, memoirs, trade reports, and military archives, this paper will examine the fall and rise of these two empires, and the efforts to create a mutually beneficial diplomatic, economic, and military partnership in the Mediterranean. From two states that had led holy wars against each other and their respective allies from the 15th to the 17th century, emerged a countervailing initiative to seek allies, as both experienced relative decline and increasingly aggressive conflicts with other European and Asian powers.
To what extent were these efforts at an alliance successful? What impact did they have on the military and economic balance in the region, as well as on the respective attempts at reform and revival in the Ottoman and Spanish Empires? Finally, what does the effort to forget this partnership have on the previous self-image of each state as a leader in holy wars against the other?
