Mirian III of Iberia

Mirian III (c. 258/277–361) founded the Chosroid dynasty and ruled Iberia, or Kartli, in Georgia. As a Sasanian Persian vassal he fought in Shah Narseh's war against Rome in 297–298, but after Persia's defeat he drew his kingdom toward Rome.

Through the preaching of Nino, a Cappadocian woman, Mirian became the first Christian king of Iberia and around 337 made Christianity the kingdom's state religion. The Georgian Orthodox Church venerates him as Saint Equal to the Apostles.
