Royal Birth and Monastic Calling
Nicholas belonged to the Bagrationi dynasty that ruled the eastern Georgian kingdom of Kakheti. His father, Levan I, reigned over Kakheti from 1520 to 1574, and Nicholas was one of his sons; sources place his birth around the year 1529. Rather than seeking the worldly honors available to a prince of the royal house, he took up the monastic life.
When the kingdom passed to his elder brother Alexandre II on Levan's death, Nicholas continued in his ecclesiastical vocation. His advancement to the highest office of the Georgian Church came in 1584, when he was enthroned as Catholicos of All Georgia.
