The holy and right-believing king Vakhtang I ascended the throne of Kartli at the age of fifteen. At that time Kartli was continually being invaded by the Persians from the south and by the Ossetians from the north. The situation was no better in western Georgia: the Byzantines had captured all the lands from Egrisi to Tsikhegoji.
After his coronation, the young King Vakhtang summoned his court and addressed his dedicated servants with great wisdom. He said that the sorrowful circumstances in which the nation had found itself were a manifestation of God’s anger at the sins of the king and the people. He called upon everyone to struggle in unity and selflessness on behalf of the Faith and motherland.
King Vakhtang led a victorious campaign against the Ossetians, freed the captive princess (his older sister), and signed several treaties with the Caucasian mountain tribes to secure their cooperation in the struggle against foreign conquerors. Then he carried out another campaign in western Georgia, freed that region from the Byzantines, reinforced the authority of King Gubaz, and returned in triumph to Kartli.
