The story of British–Ottoman relations in the long eighteenth century was marked by the arrival and departure of ships. In 1807, HMS Endymion left Istanbul with the British ambassador and factory on board, to be replaced by British warships tasked with cowing that city into submission. This final act could not have been more different from the narrative of the first relations between the two states, enshrined in the Capitulations, of the English queen sending her ships with her ambassador, gentlemen, and gifts. Within a few years of political and commercial interests being firmly separated, British foreign policy had brought disaster to the merchants trading in Istanbul. The framework of relations that had functioned for over two hundred years had seen the British merchants and ambassadors dependent on each other, the ambassadors for the finance brought in by successful commerce, and the merchants for the protection they gained from the ambassador's protection of their interests through gifts, ceremonial, and petitions that provided the displays of friendship required by the Ottoman state. The ambassadors’ negotiations had a purpose, and set practices, for a tangible aim; the maintenance of peaceful commerce through displays of friendship. This aim was shared by the Ottomans, too. In a letter to the British government concerning the conflict of the 1740s, translated by Antonio Pisani, the head tercüman of the British embassy, the grand vizier Hassan Paşa provided a glimpse of an Ottoman vision of relations:

In this view, interactions between states and their subjects were part of a single system, yet a system nonetheless dominated by constant tensions requiring compromises.
