The Giray-Ottoman suzerain-vassal relationship was long-standing, and this transfer of power further confirmed Ottoman influence over Crimean succession.
2. 1515Constantinople · IstanbulMuhammad I Giray swore allegiance to Selim I, reaffirming Crimea's status as an Ottoman vassal. The two sides agreed that Crimean cavalry could fight alongside the Ottomans in campaigns such as those against the Mamluks and in northern raids, while the Ottomans provided military protection and diplomatic recognition.
3. 1515–1520Kerch Strait · Black SeaThe strengthened Ottoman-Crimean alliance made the northern Black Sea coast a zone of Ottoman influence, with Crimean cavalry frequently raiding Moscow's southern frontier and eastern Poland-Lithuania. This order persisted for most of the 16th century and became a key variable in Eastern European geopolitics.
