• 1644 CE: Ottoman and allied forces seize control of all of Crimea except for the city of Doros and the adjoining Parathalassias region by February.

Russian forces invade northern Crimea by October, taking the entire peninsula with the exception of the city of Doros, to which they lay siege by November.
• 1702 CE: Theodoran emissaries contact the Ottomans and convince them to invade Crimea and fight back against the Russians. Ottoman forces break the siege of Doros and take the peninsula of Crimea.
