Deposition of Empress Irene

Date: October 31, 802 • Location: Ayvacık, Turkey

Empress Irene is deposed and banished to Lesbos. Conspirators place Nikephoros, the minister of finance, on the Byzantine throne.

Irene of Athens, surname Sarantapechaena, was Byzantine empress consort to Emperor Leo IV from 775 to 780, regent during the childhood of their son Constantine VI from 780 until 790, co-ruler from 792 until 797, and finally empress regnant and sole ruler of the Byzantine Empire from 797 to 802. A member of the politically prominent Sarantapechos family, she was selected as Leo IV's bride for unknown reasons in 768. Even though her husband was an iconoclast, she harbored iconophile sympathies. During her regency, in 787, she called the Second Council of Nicaea which condemned iconoclasm as heretical and brought an end to the first iconoclast period (730–787). Irene's concluding five years of sole rule were unprecedented in Roman and Byzantine history. Her public figure in this period was polarizing, due to the setbacks faced by the Empire and her iconophilic stances, often attributed to her gender and the influence of her retinue.
