Control of the Black Sea: Peter the Great recognized the strategic importance of the Black Sea region and wanted to establish Russia as a major naval power in the area. However, the Ottoman Empire's hold over the straits connecting the Black Sea to the Mediterranean prevented Russian ships from freely accessing international waters. Access to the sea was essential for expanding trade and projecting military power.
Religious and Cultural Factors: Religious factors also contributed to the conflict between Russia and the Ottoman Turks. The Russian Orthodox Church saw the Ottomans as a threat to Christianity and viewed the conquest of Ottoman territories as a holy mission. Additionally, Peter the Great aimed to unite Slavic Orthodox populations under Russian rule, including those living in territories controlled by the Ottomans.
Influence in Eastern Europe: Russia and the Ottoman Empire competed for influence in Eastern Europe, particularly among Orthodox Christian nations. Both sought to gain the allegiance or control of these nations, leading to diplomatic clashes and territorial disputes.
Historical Rivalry: There was a long-standing rivalry between Russia and the Ottoman Empire, stemming from earlier conflicts and territorial disputes. Historical tensions and mutual distrust contributed to the outbreak of hostilities.
Ultimately, Peter the Great's efforts to expand Russia's borders, gain access to the Black Sea and its desire to assert dominance in Eastern Europe led to military confrontations with the Ottoman Turks.
