Георгиевский трактат
In the late 18th century, the Sharvashidze princes embraced Islam, but shifted back and forth across the religious divide, as the Russians and Ottomans struggled for controlling the area. The pro-Russian orientation prevailed, and Abkhazia joined Imperial Russia in 1810 while the Sharvashidzes () were confirmed in the Russian princely rank in accordance with the Russo-Georgian Treaty of Georgievsk.
