The Ottomans were from the outset determined to reverse these losses, especially the Morea, whose loss had been keenly felt in the Ottoman court: a large part of the income of the Valide Sultan (the Ottoman queen-mothers) had come from there. Already in 1702, there were tensions between the two powers and rumours of war because of the Venetian confiscation of an Ottoman merchant vessel; troops and supplies were moved to the Ottoman provinces adjoining the Venetian "Kingdom of the Morea". The Venetian position there was weak, with only a few thousand troops in the whole peninsula, plagued by supply, disciplinary and morale problems. Nevertheless, peace was maintained between the two powers for twelve more years. In the meantime, the Ottomans began a reform of their navy, while Venice found itself increasingly isolated diplomatically from the other European powers: the Holy League had fractured after its victory, and the War of the Spanish Succession (1701–1714) and the Great Northern War (1700–1721) preoccupied the attention of most European states. The Ottomans took advantage of the favourable international situation to settle their scores with Russia, inflicting on them a heavy defeat in the Russo-Turkish War of 1710–1711. This victory encouraged the Ottoman leadership and after the Russo-Turkish Treaty of Adrianople in June 1713, the way was open for an attack on Venice.
