The Feast of Hundred Thousand Martyrs of Tbilisi is observed in Georgia every November 13, commemorating the events of 1226 when Jalal ad-Din Mingburnu, the first ruler of the Khwarezmian Empire, attacked Tbilisi. This assault forced Queen Rusudan to flee, leaving soldiers to defend the city, which ultimately succumbed to the invasion. The ensuing massacre targeted Christians who refused to convert to Islam, with many being decapitated for their defiance. The Sioni Cathedral, originally built in the 6th and 7th centuries, was destroyed during this period, and the icons of the Virgin Mary and Christ were desecrated, symbolizing the brutal oppression faced by the Christian population. The historical accounts suggest a significant loss of life, with the medieval Georgian chronicle indicating a toll that may be interpreted as “ten thousand.” This feast serves as a solemn reminder of the martyrdom experienced by Christians in Tbilisi during this dark chapter of history.
