In the 1570s, the Ottoman navy occupied the fort of Tskhumi on the Abkhazian coastline, turning it into the Turkish fortress of Suhum-Kale (hence, the modern name of the city of Sukhumi). In 1555, Georgia and the whole South Caucasus was divided between the Ottoman and Safavid Persian empires, with Abkhazia, along with all of western Georgia, remaining in the hands of the Ottomans. As a result, Abkhazia came under the increasing influence of Turkey and Islam, gradually losing its cultural and religious ties with the rest of Georgia.
According to the Soviet historical science Turkey after the conquest has aimed at obliterating the material and spiritual culture of Abkhazia and forcibly convert the population to Islam, which led to numerous insurrections (in 1725, 1728, 1733, 1771 and 1806) 
Towards the end of the 17th century, the principality of Abkhazia broke up into several fiefdoms, depriving many areas of any centralized authority. The region became a theatre of widespread slave trade and piracy. According to several Georgian scholars, it was when a number of the Adyghe clansmen migrated from the North Caucasus mountains and blended with the local ethnic elements, significantly changing the region's demographic situation. In the mid-18th century, the Abkhazians revolted against the Ottoman rule and took hold of Suhum-Kale, but soon the Turks regained the control of the fortress and granted it to a loyal prince of the Shervashidze family.
