Saint Nino was a 4th-century missionary from Cappadocia who played a central role in the Christianization of the Kingdom of Iberia, located in modern-day Georgia. Following a vision of the Virgin Mary, she traveled to the region to spread the faith. Her preaching successfully converted the Georgian monarchy, including Queen Nana and King Mirian III. Recognized as an equal-to-the-apostles, she is celebrated for her profound impact on the spiritual landscape of the Caucasus through her dedicated missionary work.
