In the 1820s, the Principality of Svaneti effectively split into two as a result of a blood feud between the rival Dadeshkeliani branches. Through the mediation by the princes of Mingrelia, both branches accepted nominal Russian suzerainty in 1833 as did the Free Svanetian communities in 1840. Nevertheless, they continued to run their affairs independently and did not allow Russian officials or church missions into the area until the late 1840s.
