Deposition
The remaining nobles who had escaped the massacre in the Monastery of St. Eugenios, seeing that her incompetent rule would cause a catastrophe, decided to find a legitimate claimant to the throne in the person of the daughter of Alexios II, Anna Anachoutlou. They convinced her to abandon her monastic vows and acclaimed her Empress in Lazica. Irene, when she heard of the revolt, executed all of the nobles and prisoners from the St. Eugenian massacre, but it was of no avail. The Empress's unpopularity by now was so horrible that as soon as Anna arrived at the city walls Irene was deposed on July 17, 1341. She was later sent off to Constantinople and we know nothing further of her fate.
