Tao (historical region)
Tao (Georgian: ტაო) is a historical Georgian region in the territory of modern Turkey. Its name derives from the name of Taochi, its oldest inhabitants, who were an ancient Georgian tribe. In the Middle Ages, it was a province within various Georgian royal Bagrationi kingdoms and states from the 8th to the 16th century. Afterwards, the region was conquered by the Ottoman Empire.
