Baldwin II of Jerusalem
There is no exact information whether they were auxiliary troops sent by the prince of Antioch or king Baldwin II of Jerusalem, or simply mercenaries. However, as both Franks and Georgians had one common enemy, the Muslims, it can be argued that the Frank soldiers were allies rather than mercenaries. It's supposed that Crusaders arrived to Georgia through Constantinople because the territory between Antioch and Georgia was occupied by the Seljuks.
