The first data about the family dates back to 1046. Presumably, the Dadiani descended from a certain Dadi, of the
House of Vardanisdze. Appointed as hereditary
eristavi (dukes) of
Odishi (
Samegrelo) in reward for their military services, the family had become the most powerful feudal house in western
Georgia by the 1280s. At that time, the branches of the family also governed
Svaneti,
Guria, and
Bedia. In 1542, Duke
Levan I Dadiani became hereditary Prince (
mtavari) of
Mingrelia and established himself as an independent ruler. His descendant, Prince
Levan III Dadiani, was forced to abdicate in 1691 and Dadiani’s relatives from the
House of Chikovani, hitherto Princes of
Salipartiano, inherited the title of Princes of Mingrelia and the surname of Dadiani. The original dynasty of Dadiani thus went extinct into what genealogists have termed the House of Dadiani-Chikovani. Prince Niko Dadiani officially renounced his rights to the throne in 1868. == Dadiani vs Dadányi ==
