Avag Zakarian
Avag Zakarian, son of Ivane I, succeeded his father as atabeg in 1227 and was later raised to amirspasalar, ruling Georgia's eastern lands. During the Mongol invasion of 1238–1239 he was besieged at the fortress of Kayan and became the first Caucasian prince to surrender, paying tribute and joining his troops to the Mongol army; Ani fell soon after.
In 1243 he arranged Queen Rusudan's submission to the Great Khan, and in 1245–1250 he commanded one of Georgia's eight Mongol districts. He died in 1250, leaving a daughter, Khoshak.
