Tariel "Taia" Dadiani, of the House of Dadiani, was Prince of Mingrelia from 1793 to 1794 and in 1802 as a rival to his elder brother, Grigol Dadiani, whose rule was marred by the long-standing struggle between the Imeretian crown seeking to subdue Mingrelia and Mingrelian efforts to win full independence, a continuation of the conflict which had plagued western Georgia for centuries.
