Tariel enjoyed the support of King Solomon II of Imereti, whom he joined in an uprising against the Imperial Russian encroachment in 1810.
[1] In 1791, King Solomon II of Imereti, who sought to unite all of western Georgia under his authority, deposed Grigol Dadiani and replaced him by his more amenable brother Manuchar.
Tariel, like his brother Manuchar, quickly withdraw in opposition to the new government, further exasperated by Nino's efforts to dispossess her opponents of their estates.
After Solomon's defeat, Tariel moved to the highland province of Lechkhumi and, together with the nobleman Beri Gelovani, induced the locals to take to arms, but the disturbances were quickly contained through Nino's diplomacy.
