The
Principality of Mingrelia , also known as
Odishi, was a historical state in
Georgia ruled by the
Dadiani dynasty. Established as an independent Principality in 1557 by
Levan I Dadiani as a hereditary
mtavari (Prince), it remained independent until it became subject to
Imperial Russia in 1803. The principality ultimately came to an end when Prince
Niko Dadiani was deposed, and the principality abolished, by Russia in 1867. Prince Niko officially renounced his rights to the throne in 1868.
